General Description
The ACT鈥揝512K32 is a High
Speed, 16 megabit CMOS
SRAM
Multichip
Module
(MCM) designed for full
temperature range industrial,
military, or space, mass
memory and fast cache
applications.
The MCM can be organized
as a 512K x 32 bit, 1M x 16 bit
or 2M x 8 bit device and 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)
input 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
high speed versions.
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擄C to
+125擄C and under the full
military environment. DESC
Standard Military Drawing
(SMD) numbers are released.
