General Description
The ACTS512K8 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 -55C to
+125C and under the full
military environment. A DESC
Standard Military Drawing
(SMD) number is released.
The ACT-S512K8 is
manufactured in Aeroflex's
80,000 square foot
MIL-PRF-38534 certified
facility in Plainview, N.Y.
