General Description

The ACT–S512K8 is a high

speed,

4

Megabit

CMOS

Monolithic SRAM designed for

full temperature range military,

space, or high reliability mass

memory

and

fast

cache

applications.

The MCM is input and output

TTL

compatible.

Writing

is

executed

when

the

write

enable (WE) and chip enable

(CE) inputs are low and output

enable (OE) is high. Reading is

accomplished when WE is high

and CE and OE are both low.

Access time grades of 17ns,

20ns, 25ns, 35ns, 45ns and

55ns maximum are standard.

The +5 Volt power supply

version is standard and +3.3

Volt lower power model is a

future optional product.

The products are designed

for

operation

over

the

temperature range of -55°C to

+125°C and under the full

military environment. A DESC

Standard

Military

Drawing

(SMD) number is released.
