Description
SUMO UM6164
=====~=~== BK x 8 High Speed CMOS SRAM
Features
High-speed - 45/55/70ns (Max.) Low p'ower dissipation
300mW (Typ.) Operating 100J.l.W (Typ.) standby Single 5V power supply
Fully static operation All inputs and outputs directly TTL compatible Three state outputs Data retention supply voltage: 2.0-5,5V
General Description
The UM6164 is a 65,536-bit static random access memory organized as 8192 words by 8 bits' and operates from a single 5 volt supply. It is built with UMC's high performance twin tub CMOS process. Inputs and three-state
outputs are TTL compatible and allow for direct interfacing with common system bus structures. The UM6164 is moulded in a standard 28-pin, 600 mil-DIP.
