UT62L6416  
64K X 16 BIT LOW POWER CMOS SRAM  
Preliminary Rev. 0.1  
FEATURES  
GENERAL DESCRIPTION  
The UT62L6416 is a 1,048,576-bit low power  
CMOS static random access memory organized  
as 65,536 words by 16 bits.  
Fast access time :  
55ns(max) for Vcc=3.0V~3.6V  
70/100ns(max) for Vcc=2.7V~3.6V  
CMOS Low operating power  
The UT62L6416 operates from a single 2.7V ~  
3.6V power supply and all inputs and outputs are  
fully TTL compatible.  
Operating current: 45/35/25mA (Icc max)  
Standby current: 20 uA(TYP.) L-version  
3 uA(TYP.) LL-version  
Single 2.7V~3.6V power supply  
Operating temperature:  
The UT62L6416 is design for upper and low byte  
access by data byte control(  
).  
UB LB  
Commercial : 0 ~70
