LY62L102516A  
1024K x 16 BIT LOW POWER CMOS SRAM  
Rev. 1.0  
FEATURES  
GENERAL DESCRIPTION  
The LY62L102516A is a 16,777,216-bit low power  
CMOS static random access memory organized as  
1,048,576 words by 16 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 : 4μA (TYP.) SL-version  
„ Single 2.7V ~ 3.6V power supply  
„ All inputs and outputs TTL compatible  
„ Fully static operation  
The LY62L102516A is well designed for low power  
application, and particularly well suited for battery  
back-up nonvolatile memory application.  
„ Tri-state output  
„ Data byte control :  
LB# controlled DQ0 ~ DQ7  
UB# controlled DQ8 ~ DQ15  
„ Data retention voltage : 1.2V (MIN.)  
„ Green package available  
„ Package : 48-pin 12mm x 20mm TSOP-I  
The LY62L102516A operates from a single  
power supply of 2.7V ~ 3.6V and all inputs and  
outputs are fully TTL compatible.

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.
