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 75µs per

byte. Any byte can be accessed in less than

• Fast read access time: -70ns, -90ns

and -120ns

• Fast programming algorithm

• Programming time 75µs typ.

• Two line controls (OE and CE)

• Standard product identification code

• Package type

– 32-pin DIP/SOP

– 32-pin PLCC

• Commercial temperature range

(0°C to +70°C)

70ns/90ns/120ns 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 contention issues.
