Product Brief
Storage solution for PXA270 platform
Features
Description
• ProASIC®3 A3PE600-FG484 FPGA
• Multiple I/O interface connectors and receptacles
• Motherboard connectors
The storage solution demo board is designed to
mount on the BSquare DevKit IDP270 Windows CE
development board for demonstrating storage
applications under Windows CE. Any of the featured
interfaces can be demonstrated with the proper
design programmed into the FPGA.
• Debug and expansion features
• Powered from motherboard or power jack
• CoreMP7 processor support
Any other motherboard may be used, utilizing the two
motherboard connectors and a custom flex cable
connector.
Board Block Diagram
The FPGA interfaces directly to all connectors and
devices (except USB and RS-232, which include
Phy/driver chips). The IDE connectors and
CompactFlash® connectors share pins, as do the CE-
ATA connector and the second SDIO connector.
The storage solution board can also be used
standalone if no processor is required, or if the
processor is programmed into the FPGA. RS-232
and JTAG ICE connectors facilitate CPU
programming and debug. Generous code and data
spaces
are
available
with
4 MB of bootable flash and 16 MB of SDRAM.
Additional user debug and demonstration features
include a second oscillator for greater clock flexilbity,
3 configuration DIP switches, 4 general-purpose
LEDs,
1
general-purpose pushbutton, and 16
general-purpose I/Os.
