General Description

The HT27LC512 chip family is a low-power, 512K bit,

+3.3V electrically one-time programmable (OTP)

read-only memories (EPROM). Organized into 64K

words with 8 bits per word, it features a fast single ad-

dress location programming, typically at 75ms per byte.

Any byte can be accessed in less than 90ns 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 is-

sues.
