5 Layout Guidelines  
Use good layout practices to avoid excessive noise coupling to supply voltage traces or sensitive analog  
signal traces, such as analog audio signals. If using overlapping ground planes use stitching vias separated  
by max 3 mm to avoid emission from the edges of the PCB. Connect all the GND pins directly to a solid GND  
plane and make sure that there is a low impedance path for the return current following the signal and supply  
traces all the way from start to the end.  
A good practice is to dedicate one of the inner layers to a solid GND plane and one of the inner layers to  
supply voltage planes and traces and route all the signals on top and bottom layers of the PCB. This  
arrangement will make sure that any return current follows the forward current as close as possible and any  
loops are minimized.

6 UART Interface  
This is a standard UART interface for communicating with other serial devices.WT11i UART interface provides  
a simple mechanism for communicating with other serial devices using the RS232 protocol.  
Four signals are used to implement the UART function. When WT11i is connected to another digital device,  
UART_RX and UART_TX transfer data between the two devices. The remaining two signals, UART_CTS and  
UART_RTS, can be used to implement RS232 hardware flow control where both are active low indicators. All  
UART connections are implemented using CMOS technology and have signalling levels of 0V and VDD.  
UART configuration parameters, such as data rate and packet format, are set using WT11i software.  
Note:  
In order to communicate with the UART at its maximum data rate using a standard PC, an accelerated serial  
port adapter card is required for the PC.  
Table 10: Possible UART Settings  
The UART interface is capable of resetting WT11i upon reception of a break signal. A break is identified by a  
continuous logic low (0V) on the UART_RX terminal, as shown in Figure 7. If tBRK is longer than the value,  
defined by PSKEY_HOST_IO_UART_RESET_TIMEOUT, (0x1a4), a reset will occur. This feature allows a  
host to initialise the system to a known state. Also, WT11i can emit a break character that may be used to  
wake the host.  
Figure 7: Break Signal  
Table 11 shows  
a
list of commonly used data rates and their associated values for  
PSKEY_UART_BAUD_RATE (0x204). There is no requirement to use these standard values. Any data rate  
within the supported range can be set in the PS Key according to the formula in Equation 1

6.1 UART Bypass  
Figure 8: UART Bypass Architecture  
6.2 UART Configuration While Reset is Active  
The UART interface for WT11i while the chip is being held in reset is tristate. This will allow the user to daisy  
chain devices onto the physical UART bus. The constraint on this method is that any devices connected to  
this bus must tristate when WT11i reset is de-asserted and the firmware begins to run.  
6.3 UART Bypass Mode  
Alternatively, for devices that do not tristate the UART bus, the UART bypass mode on BlueCore4-External  
can be used. The default state of BlueCore4-External after reset is de-asserted; this is for the host UART bus  
to be connected to the BlueCore4-External UART, thereby allowing communication to BlueCore4-External via  
the UART. All UART bypass mode connections are implemented using CMOS technology and have signalling  
levels of 0V and VDD.  
In order to apply the UART bypass mode, a BCCMD command will be issued to BlueCore4-External. Upon  
this issue, it will switch the bypass to PIO[7:4] as Figure 17 indicates. Once the bypass mode has been  
invoked, WT11i will enter the Deep Sleep state indefinitely.  
In order to re-establish communication with WT11i, the chip must be reset so that the default configuration  
takes effect.  
It is important for the host to ensure a clean Bluetooth disconnection of any active links before the bypass  
mode is invoked. Therefore, it is not possible to have active Bluetooth links while operating the bypass mode.  
The current consumption for a device in UART bypass mode is equal to the values quoted for a device in  
standby mode.

7 USB Interface  
This is a full speed (12Mbits/s) USB interface for communicating with other compatible digital devices. WT11i  
acts as a USB peripheral, responding to requests from a master host controller such as a PC.  
The USB interface is capable of driving a USB cable directly. No external USB transceiver is required. The  
device operates as a USB peripheral, responding to requests from a master host controller such as a PC.  
Both the OHCI and the UHCI standards are supported. The set of USB endpoints implemented can behave as  
specified in the USB section of the Bluetooth v2.1 + EDR specification or alternatively can appear as a set of  
endpoints appropriate to USB audio devices such as speakers.  
As USB is a master/slave oriented system (in common with other USB peripherals), WT11i only supports USB  
Slave operation.  
7.1 USB Data Connections  
The USB data lines emerge as pins USB_DP and USB_DN. These terminals are connected to the internal  
USB I/O buffers of the BlueCore4-External, therefore, have a low output impedance. To match the connection  
to the characteristic impedance of the USB cable, resistors must be placed in series with USB_DP/USB_DN  
and the cable.  
7.2 USB Pull-Up resistor  
WT11i features an internal USB pull-up resistor. This pulls the USB_DP pin weakly high when WT11i is ready  
to enumerate. It signals to the PC that it is a full speed (12Mbits/s) USB device.  
The USB internal pull-up is implemented as a current source, and is compliant with section 7.1.5 of the USB  
specification v1.2. The internal pull-up pulls USB_DP high to at least 2.8V when loaded with a 15k 5% pull-  
down resistor (in the hub/host) when VDD_PADS = 3.1V. This presents a Thevenin resistance to the host of  
at least 900. Alternatively, an external 1.5k pull-up resistor can be placed between a PIO line and D+ on the  
USB cable. The firmware must be alerted to which mode is used by setting PSKEY_USB_PIO_PULLUP  
appropriately. The default setting uses the internal pull-up resistor.  
7.3 USB Power Supply  
The USB specification dictates that the minimum output high voltage for USB data lines is 2.8V. To safely  
meet the USB specification, the voltage on the VDD supply terminal must be an absolute minimum of 3.1V.  
Bluegiga recommends 3.3V for optimal USB signal quality.  
7.4 Self-Powered Mode  
In self-powered mode, the circuit is powered from its own power supply and not from the VBUS (5V) line of the  
USB cable. It draws only a small leakage current (below 0.5mA) from VBUS on the USB cable. This is the  
easier mode for which to design, as the design is not limited by the power that can be drawn from the USB  
hub or root port. However, it requires that VBUS be connected to WT11i via a resistor network (Rvb1 and  
Rvb2), so WT11i can detect when VBUS is powered up. BlueCore4-External will not pull USB_DP high when  
VBUS is off.  
Self-powered USB designs (powered from a battery or PSU) must ensure that a PIO line is allocated for USB  
pullup purposes. A 1.5k 5% pull-up resistor between USB_DP and the selected PIO line should be fitted to the  
design. Failure to fit this resistor may result in the design failing to be USB compliant in self-powered mode.  
The internal pull-up in BlueCore is only suitable for bus-powered USB devices, e.g., dongles.

The terminal marked USB_ON can be any free PIO pin. The PIO pin selected must be registered by setting

**) WT11i has internal 22 ohm series resistors at the USB lines.  
7.5 Bus-Powered Mode  
In bus-powered mode, the application circuit draws its current from the 5V VBUS supply on the USB cable.  
WT11i negotiates with the PC during the USB enumeration stage about how much current it is allowed to  
consume. On power-up the device must not draw more than 100 mA but after being configured it can draw up  
to 500 mA.  
For WT11i, the USB power descriptor should be altered to reflect the amount of power required. This is  
accomplished by setting PSKEY_USB_MAX_POWER (0x2c6). This is higher than for a Class 2 application  
due to the extra current drawn by the Transmit RF PA. By default for WT11i the setting is 300 mA.  
When selecting a regulator, be aware that VBUS may go as low as 4.4V. The inrush current (when charging  
reservoir and supply decoupling capacitors) is limited by the USB specification. See the USB Specification.  
Some applications may require soft start circuitry to limit inrush current if more than 10uF is present between  
VBUS and GND. The 5V VBUS line emerging from a PC is often electrically noisy. As well as regulation down  
to 3.3V and 1.8V, applications should include careful filtering of the 5V line to attenuate noise that is above the  
voltage regulator bandwidth. Excessive noise on WT11i supply pins will result in reduced receiver sensitivity  
and a distorted RF transmit signal.  
Bluegiga Technologies Oy  
Page 19 of 38  
Figure 11: USB Connections for Bus-Powered Mode  
7.6 USB Suspend Current  
All USB devices must permit the USB controller to place them in a USB suspend mode. While in USB  
Suspend, bus-powered devices must not draw more than 2.5mA from USB VBUS (self-powered devices may  
draw more than 2.5mA from their own supply). This current draw requirement prevents operation of the radio  
by bus-powered devices during USB Suspend.  
When computing suspend current, the current from VBUS through the bus pull-up and pull-down resistors  
must be included. The pull-up resistor at the device is 1.5 k. (nominal). The pull-down resistor at the hub is  
14.25k. to 24.80k. The pull-up voltage is nominally 3.3V, which means that holding one of the signal lines high  
takes approximately 200uA, leaving only 2.3mA available from a 2.5mA budget. Ensure that external LEDs  
and/or amplifiers can be turned off by BlueCore4-External. The entire circuit must be able to enter the  
suspend mode.  
7.7 USB Detach and Wake-Up Signaling  
WT11i can provide out-of-band signaling to a host controller by using the control lines called USB_DETACH  
and USB_WAKE_UP. These are outside the USB specification (no wires exist for them inside the USB cable),  
but can be useful when embedding WT11i into a circuit where no external USB is visible to the user. Both  
control lines are shared with PIO pins and can be assigned to any PIO pin by setting  
PSKEY_USB_PIO_DETACH and PSKEY_USB_PIO_WAKEUP to the selected PIO number.  
USB_DETACH is an input which, when asserted high, causes WT11i to put USB_DN and USB_DP in high  
impedance state and turns off the pull-up resistor on DP. This detaches the device from the bus and is  
logically equivalent to unplugging the device. When USB_DETACH is taken low, WT11i will connect back to  
USB and await enumeration by the USB host.  
USB_WAKE_UP is an active high output (used only when USB_DETACH is active) to wake up the host and  
allow USB communication to recommence. It replaces the function of the software USB WAKE_UP message  
(which runs over the USB cable) and cannot be sent while BlueCore4-External is effectively disconnected  
from the bus.

7.8 USB Driver  
A USB Bluetooth device driver is required to provide a software interface between BlueCore4-External and  
Bluetooth software running on the host computer. Please, contact support@bluegiga.com for suitable drivers.  
7.9 USB v2.0 Compliance and Compatibility  
Although WT11i meets the USB specification, CSR cannot guarantee that an application circuit designed  
around the module is USB compliant. The choice of application circuit, component choice and PCB layout all  
affect USB signal quality and electrical characteristics. The information in this document is intended as a guide  
and should be read in association with the USB specification, with particular attention being given to Chapter  
7. Independent USB qualification must be sought before an application is deemed USB compliant and can  
bear the USB logo. Such qualification can be obtained from a USB plugfest or from an independent USB test  
house.  
Terminals USB_DP and USB_DN adhere to the USB Specification v2.0 (Chapter 7) electrical requirements.  
BlueCore4-External is compatible with USB v2.0 host controllers; under these circumstances the two ends  
agree the mutually acceptable rate of 12Mbits/s according to the USB v2.0 specification.

The SPI port can be used for system debugging. It can also be used for programming the Flash memory and  
setting the PSKEY configurations. WT11i uses 16-bit data and 16-bit address serial peripheral interface, where  
transactions may occur when the internal processor is running or is stopped. SPI interface is connected using  
the MOSI, MISO, CSB and CLK pins. Please, contact support@bluegiga.com for detailed information about  
the instruction cycle.

9 PCM Codec Interface  
PCM is a standard method used to digitize audio (particularly voice) for transmission over digital  
communication channels. Through its PCM interface, WT11i has hardware support for continual transmission  
and reception of PCM data, thus reducing processor overhead for wireless headset applications. WT11i offers  
a bidirectional digital audio interface that routes directly into the baseband layer of the on-chip firmware. It  
does not pass through the HCI protocol layer.  
Hardware on WT11i allows the data to be sent to and received from a SCO connection. Up to three SCO  
connections can be supported by the PCM interface at any one time.  
WT11i can operate as the PCM interface master generating an output clock of 128, 256 or 512kHz. When  
configured as PCM interface slave, it can operate with an input clock up to 2048kHz. WT11i is compatible with  
a variety of clock formats, including Long Frame Sync, Short Frame Sync and GCI timing environments.  
It supports 13-bit or 16-bit linear, 8-bit µ-law or A-law companded sample formats at 8ksamples/s and can  
receive and transmit on any selection of three of the first four slots following PCM_SYNC. The PCM  
configuration options are enabled by setting PSKEY_PCM_CONFIG32.  
WT11i interfaces directly to PCM audio devices.  
NOTE: Analog audio lines are very sensitive to RF disturbance. Use good layout practices to ensure noise  
less audio. Make sure that the return path for the audio signals follows the forward current all the way as close  
as possible and use fully differential signals when possible. Do not compromise audio routing.  
9.1 PCM Interface Master/Slave  
When configured as the master of the PCM interface, WT11i generates PCM_CLK and PCM_SYNC.  
Figure 13: PCM Interface Master  
When configured as the Slave of the PCM interface, WT11i accepts PCM_CLK rates up to 2048kHz.  
Bluegiga Technologies Oy  
Page 23 of 38  
Figure 14: PCM Interface Slave  
9.2 Long Frame Sync  
Long Frame Sync is the name given to a clocking format that controls the transfer of PCM data words or  
samples. In Long Frame Sync, the rising edge of PCM_SYNC indicates the start of the PCM word. When  
WT11i is configured as PCM master, generating PCM_SYNC and PCM_CLK, then PCM_SYNC is 8-bits long.  
When WT11i is configured as PCM Slave, PCM_SYNC may be from two consecutive falling edges of  
PCM_CLK to half the PCM_SYNC rate, i.e., 62.5s long.  
Figure 15: Long Frame Sync (Shown with 8-bit Companded Sample)  
WT11i samples PCM_IN on the falling edge of PCM_CLK and transmits PCM_OUT on the rising edge.  
PCM_OUT may be configured to be high impedance on the falling edge of PCM_CLK in the LSB position or  
on the rising edge.  
9.3 Short Frame Sync  
In Short Frame Sync, the falling edge of PCM_SYNC indicates the start of the PCM word. PCM_SYNC is  
always one clock cycle long.  
Bluegiga Technologies Oy  
Page 24 of 38  
Figure 16: Short Frame Sync (Shown with 16-bit Sample)  
As with Long Frame Sync, WT11i samples PCM_IN on the falling edge of PCM_CLK and transmits  
PCM_OUT on the rising edge. PCM_OUT may be configured to be high impedance on the falling edge of  
PCM_CLK in the LSB position or on the rising edge.  
9.4 Multi-slot Operation  
More than one SCO connection over the PCM interface is supported using multiple slots. Up to three SCO  
connections can be carried over any of the first four slots.  
Figure 17: Multi-slot Operation with Two Slots and 8-bit Companded Samples  
9.5 GCI Interface  
WT11i is compatible with the GCI, a standard synchronous 2B+D ISDN timing interface. The two 64kbits/s B  
channels can be accessed when this mode is configured.  
Bluegiga Technologies Oy  
Page 25 of 38  
Figure 18: GCI Interface  
The start of frame is indicated by the rising edge of PCM_SYNC and runs at 8kHz. With WT11i in Slave mode,  
the frequency of PCM_CLK can be up to 4.096MHz.  
9.6 Slots and Sample Formats  
WT11i can receive and transmit on any selection of the first four slots following each sync pulse. Slot  
durations can be either 8 or 16 clock cycles. Durations of 8 clock cycles may only be used with 8-bit sample  
formats. Durations of 16 clocks may be used with 8-bit, 13-bit or 16-bit sample formats.  
WT11i supports 13-bit linear, 16-bit linear and 8-bit -law or A-law sample formats. The sample rate is  
8ksamples/s. The bit order may be little or big endian. When 16-bit slots are used, the 3 or 8 unused bits in  
each slot may be filled with sign extension, padded with zeros or a programmable 3-bit audio attenuation  
compatible with some Motorola codecs.  
Bluegiga Technologies Oy  
Page 26 of 38  
Figure 19: 16-bit Slot Length and Sample Formats  
9.7 Additional Features  
WT11i has a mute facility that forces PCM_OUT to be 0. In master mode, PCM_SYNC may also be forced to  
0 while keeping PCM_CLK running which some codecs use to control power down.  
9.8 PCM_CLK and PCM_SYNC Generation  
WT11i has two methods of generating PCM_CLK and PCM_SYNC in master mode. The first is generating  
these signals by DDS from BlueCore4-External internal 4MHz clock. Using this mode limits PCM_CLK to 128,  
256 or 512kHz and PCM_SYNC to 8kHz. The second is generating PCM_CLK and PCM_SYNC by DDS from  
an internal 48MHz clock (which allows a greater range of frequencies to be generated with low jitter but  
consumes more power). This second method is selected by setting bit 48M_PCM_CLK_GEN_EN in  
PSKEY_PCM_CONFIG32. When in this mode and with long frame sync, the length of PCM_SYNC can be  
either 8 or 16 cycles of PCM_CLK, determined by LONG_LENGTH_SYNC_EN in PSKEY_PCM_CONFIG32.  
The Equation XXX describes PCM_CLK frequency when being generated using the internal 48MHz clock:  
Bluegiga Technologies Oy  
Page 27 of 38  
Equation 2: PCM_CLK Frequency When Being Generated Using the Internal 48MHz Clock  
The frequency of PCM_SYNC relative to PCM_CLK can be set using Equation XXX:  
Equation 3: PCM_SYNC Frequency Relative to PCM_CLK

9.9 PCM Configuration  
The PCM configuration is set using two PS Keys, PSKEY_PCM_CONFIG32 detailed in Table 12 and  
PSKEY_PCM_LOW_JITTER_CONFIG in Table 13. The default for PSKEY_PCM_CONFIG32 is 0x00800000,  
i.e., first slot following sync is active, 13-bit linear voice format, long frame sync and interface master  
generating 256kHz PCM_CLK from 4MHz internal clock with no tri-state of PCM_OUT.

10 I/O Parallel Ports  
Six lines of programmable bidirectional input/outputs (I/O) are provided. All the PIO lines are power from VDD.  
PIO lines can be configured through software to have either weak or strong pull-ups or pull-downs. All PIO  
lines are configured as inputs with weak pull-downs at reset. Any of the PIO lines can be configured as  
interrupt request lines or as wake-up lines from sleep modes.  
WT11i has a general purpose analogue interface pin AIO[1]. This is used to access internal circuitry and  
control signals. It may be configured to provide additional functionality.  
Auxiliary functions available via AIO[1] include an 8-bit ADC and an 8-bit DAC. Typically the ADC is used for  
battery voltage measurement. Signals selectable at this pin include the band gap reference voltage and a  
variety of clock signals: 48, 24, 16, 8MHz and the XTAL clock frequency. When used with analogue signals,  
the voltage range is constrained by the analogue supply voltage internally to the module (1.8V). When  
configured to drive out digital level signals (e.g., clocks), the output voltage level is determined by VDD.  
10.1PIO Defaults  
Bluegiga cannot guarantee that these terminal functions remain the same. Refer to the software release note  
for the implementation of these PIO lines, as they are firmware build-specific.  
Bluegiga Technologies Oy  
Page 30 of 38  
11 Reset  
WT11i may be reset from several sources: RESET pin, power on reset, a UART break character or via  
software configured watchdog timer. The RESET pin is an active low reset and is internally filtered using the  
internal low frequency clock oscillator. A reset will be performed between 1.5 and 4.0ms following RESETB  
being active. It is recommended that RESET be applied for a period greater than 5ms.  
The power on reset occurs when the VDD_CORE supply internally to the module falls below typically 1.5V  
and is released when VDD_CORE rises above typically 1.6V. At reset the digital I/O pins are set to inputs for  
bidirectional pins and outputs are tri-state.

OEM integrator is still responsible for testing their end-product for any additional compliance requirements  
required with this module installed (for example, digital device emissions, PC peripheral requirements, etc.).  
IMPORTANT NOTE: In the event that these conditions cannot be met (for certain configurations or co-location  
with another transmitter), then the FCC and Industry Canada authorizations are no longer considered valid  
and the FCC ID and IC Certification Number cannot be used on the final product. In these circumstances, the  
OEM integrator will be responsible for re-evaluating the end product (including the transmitter) and either  
obtaining a separate FCC and Industry Canada authorization or ask for Bluegiga to make a Class 2  
Permissive Change to the listing of the module. With a Class 2 Permissive Change the OEM integrator can  
still use the FCC ID and IC Certification Number of the module in the final product and the responsibility of  
compliance remains at Bluegiga.  
End Product Labeling  
The WT11i-E Module is labeled with its own FCC ID and IC Certification Number. If the FCC ID and IC  
Certification Number are not visible when the module is installed inside another device, then the outside of the  
device into which the module is installed must also display a label referring to the enclosed module. In that  
case, the final end product must be labeled in a visible area with the following:  
“Contains Transmitter Module FCC ID: QOQWT11I”  
“Contains Transmitter Module IC: 5123A-BGTWT11I”  
or  
“Contains FCC ID: QOQWT11I  
“Contains IC: 5123A-BGTWT11I”  
The OEM of the WT11i-E module must only use the approved antenna.  
The OEM integrator has to be aware not to provide information to the end user regarding how to install or  
remove this RF module or change RF related parameters in the user manual of the end product.
