General Description
The ACT–RS128K32 is a High
Speed 4 megabit CMOS SRAM
Multichip Module (MCM)
designed for full temperature
range, 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
35ns and 45ns maximum are
standard.
The +5 Volt power supply
version is 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-RS128K32 is
manufactured in Aeroflex’s
80,000ft2
MIL-PRF-38534
certified facility in Plainview,
N.Y.
