-  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.

   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 pin
-  Write Protect (WP#) function allows
protection of first or last *2K-word sector,
regardless of previous sector protect status
-  Acceleration (ACC) function provides
accelerated program times

GENERAL DESCRIPTION 
The EN*9LV**0H/L / EN*9LV**0U is a **-Megabit ( 4Mx*6 ), 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. 
The EN*9LV**0H/L / EN*9LV**0U 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 **0K
program/erase cycles on each Sector.
