UM61512A Series  
64K X 8 BIT HIGH SPEED CMOS SRAM  
Features  
Single +5V power supply  
Common I/O using three-state output  
Output enable and two chip enable inputs for easy  
application  
Access times: 15/20/25ns (max.)  
Current: Operating: 160mA (max.)  
Standby: 10mA (max.)  
Data retention voltage: 3V (min.)  
Full static operation, no clock or refreshing required  
All inputs and outputs are directly TTL compatible  
Available in 32-pin SKINNY DIP, TSOP, SOP, SOJ  
and both 300/400 mil packages  
General Description  
The UM61512A is a low operating current 524,288-bit  
static random access memory organized as 65,536  
words by 8 bits and operates on a single 5V power  
supply. It is built using UMC's high performance CMOS  
process.  
Two chip enable inputs are provided for POWER-DOWN  
and device enable and an output enable input is included  
for easy interfacing.  
Data retention is guaranteed at a power supply voltage  
as low as 3V.  
Inputs and three-state outputs are TTL compatible and  
allow for direct interfacing with common system bus  
structures.
