Full static operation, no clock or refreshing required All inputs and outputs are directly TTL compatible Common I/O using three-state output Output enable and two chip enable inputs for easy application Data retention voltage: 3V (min.) 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. Inputs and three-state outputs are TTL compatible and allow for direct interfacing with common system bus structures. 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.
