Issue 4.1 April 1999
General Description
The PUMA 2F4006 is a 4,194,304 bit CMOS 5.0V
only FLASH memory in a 66 pin ceramic PGA
package, which is configurable as 8, 16, 32 bit wide
output using four chip selects.Flash memory
combines the functionality of EEPROM with on chip
electrical Write/Erase logic, thus simplifying the
external control circuitry. The PUMA 2F4006
incorporates Automatic Programming and Erase
functions, which allow up to 10,000 Write/Erase
cycles (min).
In addition, a Sector Erase function is available
which can erase one 16K block of data randomly
and more than one block simultaneously. The PUMA
2F4006 also features hardware sector protection,
which enables both program and erase operations in
any of the 32 sectors on the module.
Features
鈥?Very Fast Access Times of 70ns/90ns/120ns.
鈥?Operating Power (Read) 660 mW (Max)
(Program/Erase) 1100 mW (Max)
Standby Power
2.2 mW (Max)
Output Configurable as 32 / 16 / 8 bit wide.
鈥?Automatic Write/Erase by Embedded Algorithm -
end of Write/Erase indicated by DATA Polling and
Toggle Bit.
鈥?Flexible Sector Erase Architecture - 16K byte sector
size, with hardware protection of any number of
sectors.
鈥?Single Byte Program of 14碌s (typical), Sector Pro
gram time of 0.3 sec. (typical).
鈥?Module FLASH Erase of 3 seconds (typical).
鈥?Erase/Write Cycle Endurance 10,000 (minimum)
鈥?Can be screened in accordance with MIL-STD-883.
