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 onAMDs MirrorBitAM29LV160M
- 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
