LY62L205016A  
32M Bits ( 2Mx16 / 4Mx8 Switchable) LOW POWER CMOS SRAM  
Rev. 1.2  
FEATURES  
GENERAL DESCRIPTION  
„ Fast access time : 55/70ns  
„ Low power consumption:  
Operating current : 45/30mA (TYP.)  
Standby current : 10μA (TYP.) SL-version  
„ Single 2.7V ~ 3.6V power supply  
„ All inputs and outputs TTL compatible  
„ Fully static operation  
The LY62L205016A is a 33,554,432-bit low power  
CMOS static random access memory organized as  
2,097,152 words by 16 bits or 4,194,304 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.  
„ Tri-state output  
„ Data byte control :  
The LY62L205016A is well designed for low power  
application, and particularly well suited for battery  
back-up nonvolatile memory application.  
(i) BYTE# fixed to VCC  
LB# controlled DQ0 ~ DQ7  
UB# controlled DQ8 ~ DQ15  
(ii) BYTE# fixed to VSS  
The LY62L205016A operates from a single  
power supply of 2.7V ~ 3.6V and all inputs and  
outputs are fully TTL compatible  
DQ15 used as address pin, while  
DQ8~DQ14 pins not used  
„ Data retention voltage : 1.2V (MIN.)  
„ Green package available  
„ Package : 48-pin 12mm x 20mm TSOP-I

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.
