General Description
The ACT鈥揊128K32 is a high
speed, 4 megabit CMOS flash
multichip
module
(MCM)
designed for full temperature
range military, space, or high
reliability 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 TTL and output CMOS
compatible.
The
command
register is written by bringing
WE to a logic low level (V
IL
),
while CE is low and OE is at
logic high level (V
IH
)
. Reading is
accomplished by chip Enable
(CE) and Output Enable (OE)
being logically active, see
60ns, 70ns, 90ns, 120ns and
150ns maximum are standard.
The
ACT鈥揊128K32
is
packaged in a hermetically
