GENERAL DESCRIPTION
The EN29LV512 is a 512-Kbit, electrically erasable, read/write non-volatile flash memory, organized
as 65,536 bytes. Any byte can be programmed typically in 8µs. The EN29LV512 features 3.0V
voltage read and write operation, with access times as fast as 45ns to eliminate the need for WAIT
states in high-performance microprocessor systems.
The EN29LV512 has separate Output Enable (
OE
), Chip Enable (
CE
), and Write Enable (WE)
controls, which eliminate bus contention issues. This device is designed to allow either single
Sector or full chip erase operation, where each Sector can be individually 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.

Note:
1. A8=H is recommended for manufacture ID check. If a manufacture ID is read with A8=L, the chip will output a configuration
code 7Fh.
2. A9 = VID is for HV A9 Autoselect mode only. A9 must be
≤
Vcc (CMOS logic level) for Command Autoselect Mode.
