Issue 4.2 : December 1999
Description
The PUMA 68F32006 is a high density 32Mbit
CMOS 5V Only FLASH memory organised as
1M x 32 in a JEDEC 68 pin surface mount
PLCC, with read access times of 90, 120, and
150ns.
The output width is user configurable as 8 , 16
or 32 bits using four Chip Selects (CE1~4) for
optimum application flexibility.
The module incorporates Embedded Algorithms
for Program and Erase with Sector architecture
(64K sector) and supports full chip erase.
The device also features hardware sector
protection, which disables both program and
erase operations in any of the 64 sectors on the
module.
A version 'A' with four independant write enables
(WE1-4) is available.
