W7MG1M32SVx-BN

W7MG21M32SVx-BN

May 2004

Rev. 2

PRELIMINARY*

DESCRIPTION

The W7MG1M32SVx-BN and W7MG21M32SVx-BN are

organized as one and two banks of 1Mx32 respectively.

The modules are based on AMDs MirrorBit™ AM29LV160M

- 1Mx16 or S29AL016M (optional) Flash device in TSOP

packages which are mounted on an FR4 substrate.

Both modules offer access times between 70 and 120ns

allowing for operation of high-speed microprocessors

without wait states.

FEATURES

1Mx32 and 2x1Mx32 Densities

Based on AMD - AM29LV160M Flash Device

Spansion™ - S29AL016M (optional)

High Performance

• Access time as fast as 70ns

• 0.7s typical sector erase time

3V for read, erase, and program operations

Flexible, Sector Architecture

• One 16Kbyte, two 8Kbyte, one 32Kbyte and

thirty-one 64Kbyte sectors.

• Any combination of sectors can be erased

• Also supports full chip erase

W7MG1M32SVx-BN: 1Mx32 80 PIN SIMM

W7MG21M32SVx-BN: 2x1Mx32 80 PIN SIMM

8MB/4MB (2x1Mx32 / 1Mx32) MirrorBit™ 3.0V, Boot Sector
