LY62W25616  
256K X 16 BIT LOW POWER CMOS SRAM  
GENERAL DESCRIPTION  
Rev. 1.4  
FEATURES  
The LY62W25616 is a 4,194,304-bit low power  
CMOS static random access memory organized as  
262,144 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 : 30/20mA (TYP.)  
Standby current : 4μA (TYP.) LL-version  
3μA (TYP.) SL-version  
„ Single 2.7V ~ 5.5V power supply  
„ All outputs TTL compatible  
„ Fully static operation  
„ Tri-state output  
„ Data byte control : LB# (DQ0 ~ DQ7)  
UB# (DQ8 ~ DQ15)  
„ Data retention voltage : 1.5V (MIN.)  
„ Green package available  
„ Package : 44-pin 400 mil TSOP-II  
48-ball 6mm x 8mm TFBGA  
The LY62W25616 is well designed for low power  
application, and particularly well suited for battery  
back-up nonvolatile memory application.  
The LY62W25616 operates from a single power  
supply of 2.7V ~ 5.5V and all inputs and outputs are  
fully TTL compatible

4.tCLZ, tBLZ, tOLZ, tCHZ, tBHZ and tOHZ are specified with CL = 5pF. Transition is measured ±500mV from steady state.  
5.At any given temperature and voltage condition, tCHZ is less than tCLZ , tBHZ is less than tBLZ, tOHZ is less than tOLZ.

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