General Description
The ACT–F512K32 is a high
speed, 16 megabit CMOS flash
multichip module (MCM)
designed for full temperature
range military, space, or high
reliability applications.
The MCM can be organized
as a 512K x 32bits, 1M x 16bits
or 2M x 8bits device and is input
TTL and output CMOS
compatible. The command
register is written by bringing
WE to a logic low level (VIL),
while CE is low and OE is at
logic high level (VIH). Reading is
accomplished by chip Enable
(CE) and Output Enable (OE)
being logically active, see
Figure 9. Access time grades of
60ns, 70ns, 90ns, 120ns and
150ns maximum are standard.
The ACT–F512K32 is
packaged in a hermetically
