Description

The HT27LC020 chip family is a low-power, 2048K (2,097,152) bit, +3.3V 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's 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 contention issues.
