LY62102616  
1024K X 16 BIT LOW POWER CMOS SRAM  
Rev. 0.3  
FEATURES  
GENERAL DESCRIPTION  
The LY62102616 is a 16,777,216-bit low power  
CMOS static random access memory organized as  
1,048,576 words by 16 bits or 2,097,152 words by 8  
bits. It is fabricated using very high performance,  
high reliability CMOS technology. Its standby current  
is stable within the range of operating temperature.  
„ Fast access time : 55/70ns  
„ Low power consumption:  
Operating current : 45/30mA (TYP.)  
Standby current : 10μA (TYP.) LL-version  
„ Single 4.5V ~ 5.5V power supply  
„ All inputs and outputs TTL compatible  
„ Fully static operation  
The LY62102616 is well designed for low power  
application, and particularly well suited for battery  
back-up nonvolatile memory application.  
„ Tri-state output  
„ Data byte control :  
(i) BYTE# fixed to VCC  
LB# controlled DQ0 ~ DQ7  
UB# controlled DQ8 ~ DQ15  
(ii) BYTE# fixed to VSS  
The LY62102616 operates from a single power  
supply of 4.5V ~ 5.5V and all inputs and outputs are  
fully TTL compatible  
DQ15 used as address pin, while LB#,  
UB# and DQ8~DQ14 pins not used  
„ Data retention voltage : 1.5V (MIN.)  
„ Green package available  
„ Package : 48-pin 12mm x 20mm TSOP-I

Notes :  
1.WE#,CE#, LB#, UB# must be high or CE2 must be low during all address transitions.  
2.A write occurs during the overlap of a low CE#, high CE2, low WE#, LB# or UB# = low.  
3.During a WE# controlled write cycle with OE# low, tWP must be greater than tWHZ + tDW to allow the drivers to turn off and data to be  
placed on the bus.  
4.During this period, I/O pins are in the output state, and input signals must not be applied.  
5.If the CE#, LB#, UB# low transition and CE2 high transition occurs simultaneously with or after WE# low transition, the outputs remain  
in a high impedance state.  
6.tOW and tWHZ are specified with CL = 5pF. Transition is measured ±500mV from steady state.
