LY62L2568  
256K X 8 BIT LOW POWER CMOS SRAM  
Rev. 1.5  
FEATURES  
GENERAL DESCRIPTION  
The LY62L2568 is a 2,097,152-bit low power CMOS  
static random access memory organized as 262,144  
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 : 23/20/18mA (TYP.)  
Standby current : 1μA (TYP.) LL/SL -version  
„ Single 2.7V ~ 3.6V power supply  
„ All inputs and outputs TTL compatible  
„ Fully static operation  
The LY62L2568 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 LY62L2568 operates from a single power  
supply of 2.7V ~ 3.6V and all inputs and outputs are  
fully TTL compatible

3. Over/Undershoot specifications are characterized, not 100% tested.  
4. Typical values are included for reference only and are not guaranteed or tested.  
Typical values are measured at VCC = VCC(TYP.) and TA = 25  
5. This parameter is measured at VCC = 3.0V

3.Address must be valid prior to or coincident with CE# = low, CE2 = high; otherwise tAA is the limiting parameter.  
4.tCLZ, tOLZ, tCHZ 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 , tOHZ is less than tOLZ.

Notes :  
1.WE#, CE# 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#.  
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 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.
