General Description

The HT27LC512 chip family is a low-power,

512K bit, +3.3V electrically one-time pro-

grammable

(O TP ) read-o nly memories

(EPROM). Organized into 64K words with 8

bits per word, it features a fast single address

location programming, typically at 75

µs per

byte. Any byte can be accessed in less than 120ns

with respect to Spec. This eliminates the need for

WAIT states in high-performance microprocessor

systems. The HT27LC512 has separate Output Enable

(OE) and Chip Enable (CE) controls which

eliminate bus contention issues.
