GENERAL DESCRIPTION

The EN27C020 is a low-power 2-Megabit, 5V-only one-time-programmable (OTP) read-only

memory (EPROM). Organized into 256K words with 8 bits per word, it features QuikRiteTM single-

address location programming, typically at 20µs per byte. Any byte can be accessed in less than

45ns, eliminating the need for WAIT states in high-performance microprocessor systems. The

EN27C020 has separate Output Enable ( OE ) and Chip Enable ( CE ) controls which eliminate

bus contention issues.
