General Description
Utilizing Samsung SRAM die,
the ACT–S128K32V is a High
Speed 4 megabit CMOS SRAM
Multichip Module (MCM)
designed for full temperature
range, 3.3V Power Supply,
military, space, or high
reliability mass memory and
fast cache applications.
The MCM can be organized
as a 128K x 32 bits, 256K x 16
bits or 512k x 8 bits device and
is input and output TTL
compatible. Writing is
executed when the write enable
(WE) and chip enable (CE)
inputs are low. Reading is
accomplished when WE is high
and CE and output enable (OE)
are both low. Access time
grades of 17ns, 20ns, 25ns,
35ns, 45ns and 55ns maximum
are standard.
The products are designed for
operation over the temperature
range of -55°C to +125°C and
screened under the full military
environment. DESC Standard
Military Drawing (SMD) part
numbers are pending.
The ACT-S128K32V is
manufactured in Aeroflex’s
80,000ft2 MIL-PRF-38534
certified facility in Plainview,
N.Y.
