LY625128  
512K X 8 BIT LOW POWER CMOS SRAM  
Rev. 2.5  
FEATURES  
GENERAL DESCRIPTION  
The LY625128 is a 4,194,304-bit low power CMOS  
static random access memory organized as 524,288  
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 : 45/55/70ns  
„ Low power consumption:  
Operating current : 45/40/30mA (TYP.)  
Standby current : 5μA@5V(TYP.) LL/SL version  
3μA@3V(TYP.) SL version  
„ Single 4.5V ~ 5.5V power supply  
„ All inputs and outputs TTL compatible  
„ Fully static operation  
The LY625128 is well designed for very low power  
system applications, and particularly well suited for  
battery back-up nonvolatile memory application.  
„ Tri-state output  
„ Data retention voltage : 1.5V (MIN.)  
„ Green package available  
„ Package : 32-pin 450 mil SOP  
32-pin 8mm x 20mm TSOP-I  
32-pin 8mm x 13.4mm STSOP  
36-ball 6mm x 8mm TFBGA  
The LY625128 operates from a single power  
supply of 4.5V ~ 5.5V and all inputs and outputs are  
fully TTL compatible

1.WE#, CE# must be high during all address transitions.  
2.A write occurs during the overlap of a low CE#, low WE#.  
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# low 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.
