LY62L20488  
2048K X 8 BIT LOW POWER CMOS SRAM  
Rev. 1.1  
FEATURES  
GENERAL DESCRIPTION  
The LY62L20488 is a 16,777,216-bit low power  
CMOS static random access memory organized as  
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  
4μA (TYP.) SL-version  
„ Single 2.7V ~ 3.6V power supply  
„ All inputs and outputs TTL compatible  
„ Fully static operation  
The LY62L20488 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 : 1.2V (MIN.)  
„ Green package available  
„ Package : 44-pin 400 mil TSOP-II  
48-ball 6mm x 8mm TFBGA  
The LY62L20488 operates from a single power  
supply of 2.7V ~ 3.6V and all inputs and outputs are  
fully TTL compatible

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.

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.
