General Description
The HT27C010 chip family is a low-power, 1024K
(1,048,576) bit, +5V electrically one-time programmable
(OTP) read-only memories (EPROM). Organized into
128K 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 70ns with
respect to Spec. This eliminates the need for WAIT
states in high-performance microprocessor systems.
The HT27C010 has separate Output Enable (OE) and
Chip Enable (CE) controls which eliminate bus conten-
tion issues.
