General Description

The HT27C020 chip family is a low-power,

2048K (2,097,152) bit, +5V electrically one-time

programmable (OTP) read-only memories

(EPROM). Organized into 256K 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

70ns/90ns/120ns with respect to Spec. This

eliminates the need for WAIT states in high-

performance microprocessor systems. The

HT27C020 has separate Output Enable (OE)

and Chip Enable (CE) controls which eliminate

bus contention issues.
