General Description
The HT27C020 chip family is a low-power,
2048K (2,097,152) bit, +5V electrically one-time
programmable (OTP) read-only memories
(E PROM). Organized into 256K words with 8
bits per word, it features a fast single address
location programming, typically at 75
μ
s per
byte. Any byte can be accessed in less than
70ns/90ns/120ns with respect to Spec. This
eliminates the need for WAIT states in high-
performance microprocessor systems. T he
HT27C020 has separate Output E nable (OE )
and Chip E nable (CE ) controls which eliminate
bus contention issues.
