Issue 1.4 : May 2001
Description
The PUMA 68FV32006 is a high density 32Mbit
CMOS 3.3V 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
plastic device is screened to ensure high reliability.
The output width is user configurable as 8 , 16 or 32
bits using four Chip Selects (CS1~4) for optimum
application flexibility.
The device incorporates Embedded Algorithms for
Program and Erase with Sector architecture (64K
sector) and supports full chip erase.
The PUMA 68FV32006 also features hardware
sector protection, which disables both program and
erase operations in any of the 32 sectors on the
device.
Features
鈥?Fast Access Times of 90/120/150 ns.
鈥?Output Configurable as 32 / 16 / 8 bit wide.
鈥?Operating Power 660/330/165 mW (Max).
鈥?Low Power Standby 1.1mA (Max).
鈥?Industrial and Military (Restricted) grade parts.
鈥?Automatic Write/Erase by Embedded Algorithm - end
of Write/Erase indicated by DATA Polling and Toggle
Bit.
鈥?Flexible Sector Erase Architecture - 64K byte sector
size, with hardware protection of any number of
sectors.
鈥?3.3V operation, 3.3V program.
鈥?Single Byte Program Time of 9碌S (Typ).
鈥?Sector Program Time of 1sec (Typ).
鈥?Erase/Write Cycle Endurance 100,000 (Min).
