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

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 perform-
ance 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.

Notes: 1. WE is high for READ cycle.
2. Device is continuously selected CSl = VI Land CS 2 = VIH.
3. Address valid prior to or coincident with CSl transition low.
4. OE = VIL.
5. Transition is measured ± 500mV from steady state. This parameter is sampled and not 100% tested.
6. CS2 is high.
7. CSl is low.
