PRELIMINARY*
8MB/4MB (2x1Mx32 / 1Mx32) MirrorBit™ 3.0V, Boot Sector
Flash Memory Module
DESCRIPTION
Top boot block configurations
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.
• Bottom boot block optional. Contact WEDC.
Embedded Erase Algorithms
• Automatically preprograms and erases the chip
or any combination of sectors
Embedded Program Algorithms
Both modules offer access times between 70 and 120ns
allowing for operation of high-speed microprocessors
without wait states.
FEATURES
• Automatically programs and verifies data at
specified address
Data Polling and Toggle Bit feature for detection of
program or erase cycle completion
Low Power Dissipation
1Mx32 and 2x1Mx32 Densities
• 30mA per Device Active Current
Based on AMD - AM29LV160M Flash Device
• 10µA per Device CMOS Standby Current
Spansion™ - S29AL016M (optional)
Single 3.3V ±10% Supply
High Performance
CMOS and TTL Compatible Inputs and Outputs
• Access time as fast as 70ns
• 0.7s typical sector erase time
3V for read, erase, and program operations
Flexible, Sector Architecture
