General Description

The HT27LC020 chip family is a low-power,

2048K (2,097,152) bit, +3.3V electrically

one-time programmable (OTP) read-only mem-

ories (EPROM). Organized into 256K words

with 8 bits per word, it features a fast single ad-

dress location programming, typically at 75ms

per byte. Any byte can be accessed in less than

120ns with respect to Spec. This eliminates the

need for WAIT states in high-performance mi-

croprocessor systems. The HT27LC020 has

separate Output Enable (OE) and Chip Enable

(CE) controls which eliminate bus contention

issues.
