W7MG21M32SVx-BN
PRELIMINARY*
8MB/4MB (2x1Mx32 / 1Mx32) MirrorBit鈩?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鈩?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.
Top boot block con鏗乬urations
鈥?Bottom boot block optional. Contact WEDC.
Embedded Erase Algorithms
鈥?Automatically preprograms and erases the chip
or any combination of sectors
Embedded Program Algorithms
鈥?Automatically programs and veri鏗乪s data at
speci鏗乪d address
