GENERAL DESCRIPTION
The EN29LV640H/L / EN29LV640U is a 64-Megabit ( 4Mx16 ), electrically erasable, read/write non-
volatile flash memory. Any word can be programmed typically in 8μs. This device is entirely
command set compatible with the JEDEC single-power-supply Flash standard.
Sector Group Protection
- Provide locking of sectors to prevent program
or erase operations within individual sectors
- Additionally, temporary Sector Group
Unprotect allows code changes in previously
protected sectors.
Software features:
Standard DATA# polling and toggle bits
feature
Unlock Bypass Program command supported
Sector Erase Suspend / Resume modes:
Read and program another Sector during
Sector Erase Suspend Mode
Support JEDEC Common Flash Interface
(CFI).
Hardware features:
Pin compatible to lower density, easy
replacement for code expansion.
RESET# hardware reset pin
- Hardware method to reset the device to read
mode.
WP#/ACC input pin
- Write Protect (WP#) function allows
protection of first or last 32K-word sector,
regardless of previous sector protect status
- Acceleration (ACC) function provides
accelerated program times
The EN29LV640H/L / EN29LV640U is designed to allow either single Sector or full Chip erase
operation, where each Sector Group can be protected against program/erase operations or
temporarily unprotected to erase or program. The device can sustain a minimum of 100K
program/erase cycles on each Sector.
