General Description

The HT27LC040 chip family is a low-power, 4096K

(4,194,304) bits, +3.3V electrically one-time program-

mable (OTP) read-only memories (EPROM). Organized

into 512K words with 8 bits per word, it features a fast

single address location programming, typically at 75

ms

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 HT27LC040 has separate Output Enable (OE) and

Chip Enable (CE) controls which eliminate bus conten-

tion issues.
