General Description
The ACT鈥揊512K32 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 (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
Figure 9. Access time grades of
60ns, 70ns, 90ns, 120ns and
150ns maximum are standard.
