The ACT–E128K32 is a high
speed, 4 megabit, CMOS
EEPROM multichip module
(MCM) designed for full
temperature range military,
space, or high reliability
applications. The MCM can be
organized as a 256K x 16 bits
or 512K x 8 bits device and is
input and output CMOS and
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 times grades of
120, 140, 150, 200, 250 & 300ns
are standard.
The ACT–E128K32 is
packaged in a choice of
hermetically sealed co-fired
ceramic packages, a 66 pin,
1.08" sq PGA or a 68 lead, .88"
sq gullwing CQFP. The device
operates over the temperature
range of -55°C to +125°C and
military environment.
