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
• Fast Access Times of 90/120/150 ns.
• Output Configurable as 32 / 16 / 8 bit wide.
• Operating Power 660/330/165 mW (Max).
• Low Power Standby 1.1mA (Max).
• Industrial and Military (Restricted) grade parts.
• Automatic Write/Erase by Embedded Algorithm - end
of Write/Erase indicated by DATA Polling and Toggle
Bit.
• Flexible Sector Erase Architecture - 64K byte sector
size, with hardware protection of any number of
sectors.
• 3.3V operation, 3.3V program.
• Single Byte Program Time of 9µS (Typ).
• Sector Program Time of 1sec (Typ).
• Erase/Write Cycle Endurance 100,000 (Min).

Stresses above those listed may cause permanent damage to the device. This is a stress rating only and functional
operationof the device at those or any other conditions above those indicated in the operational sections of this specification
is not implied.
Minimum DC voltage on any input or I/O pin is -0.5V. Maximum DC voltage on output and I/O pins is Vcc+0.5V
During transitions voltage may overshoot to Vcc +1.0V for periods of 10ns
Minimum DC input voltage on A9,OE, Reset is -0.5V during voltage transitions, A9,OE, Reset may overshoot Vss to -1V
for periods of up to 10ns, maximum DC input voltage on A9 is 12.5V which may overshoot to 14.0V for periods up to 10ns.
