GENERAL DESCRIPTION
The EN29F512 is a 512-Kbit, electrically erasable, read/write non-volatile flash memory. Organized
into 64K bytes with 8 bits per byte, the 512K of memory is arranged in four uniform sectors of
16Kbytes each. Any byte can be programmed typically in 7µs. The EN29F512 features 5.0V
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 EN29F512 has separate Output Enable (
OE
), Chip Enable (
CE
), and Write Enable (
W E
)
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.
