General Description

The ACT–E128K32 is a high

speed,

4

megabit,

CMOS

EEPROM

multichip

module

(MCM)

designed

for

full

temperature

range

military,

space,

or

high

reliability

applications. The MCM can be

organized as a 256K x 16 bits

or 512K x 8 bits device and is

input and output CMOS and

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

times

grades

of

120, 140, 150, 200, 250 & 300ns

are standard.

The

ACT–E128K32

is

packaged

in

a

choice

of

hermetically

sealed

co-fired

ceramic packages, a 66 pin,

1.08" sq PGA or a 68 lead, .88"

sq gullwing CQFP. The device

operates over the temperature

range of -55°C to +125°C and

military environment.
