PRELIMINARY*
8MB/4MB (2x1Mx32 / 1Mx32) MirrorBit™ 3.0V, Boot Sector
Flash Memory Module
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.
