General Description
The HT27LC020 chip family is a low-power, 2048K
(2,097,152) bit, +3.3V electrically one-time programma-
ble (OTP) read-only memories (EPROM). Organized
into 256K words with 8 bits per word, it features a fast
single address 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 HT27LC020 has separate Output Enable (OE) and
Chip Enable (CE) controls which eliminate bus conten-
tion issues.
