Description
The PUMA 68E4001/A is a 4Mbit CMOS
EEPROM module in a JEDEC 68 pin surface
mount PLCC. The plastic device is screened to
ensure high reliability. Access times of 120, 150
and 200ns are available.The output width is user
configurable as 8, 16, or 32 bits wide using CS1-4
and is available in two pinout options, single WE
or WE1-4 (version /A) . Page write (128 bytes) is
performed in 5 ms (typical). The device also
features both hardware and software data protec-
tion with DATA polling and Toggle bit indication of
end of write . Write cycle endurance is 10,000
Erase/Write cycles with a data retention time of 10
years.
