General Description

Utilizing AMD’s Sector Erase Flash Memory Die, the ACT-F4M32A is a high speed, 128

megabit CMOS flash multichip module (MCM) designed for full temperature range, military,

space, or high reliability applications.

The ACT-F4M32A consists of eight high-performance AMD

Am29F016 16Mbit

(16,777,216 bit) memory die. Each die contains 8 separately write or erase sector groups

of 256Kbytes (A sector group consists of 4 adjacent sectors of 64Kbytes each).

(OE) being logically active. Access time grades of 100ns, 120ns and 150ns maximum are

standard.

The ACT-F4M32A is offered in two different hermetically sealed co-fired 68 lead

ceramic packages. This allows operation in a military environment temperature range of

-55°C to +125°C.

The ACT-F4M32A can be programmed (both read and write functions) in-system using

operations. The end of program or erase is detected by the RY/BY pin, Data Polling of

DQ7, or by the Toggle bit (DQ6).

The ACT-F4M32A also has a hardware RESET pin. When this pin is driven low,

execution of any Embedded Program Alggorithm or Embedded Erase Algorithm will be

terminated.

Each block can be independently erased and programmed 100,000 times at +25°C.

Memory, see the AMD datasheet (Publication 18805).
