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 s
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.
