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 8碌s. This device is entirely
command set compatible with the JEDEC single-power-supply Flash standard.
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.
