GENERAL DESCRIPTION
The EN27C010 is a low-power 1-Megabit, 5V-only one-time-programmable (OTP) read-only
memory (EPROM). Organized into 128K words with 8 bits per word, it features QuikRite
TM single-
address location programming, typically at 20
µs per byte. Any byte can be accessed in less than
45ns, eliminating the need for WAIT states in high-performance microprocessor systems. The
EN27C010 has separate Output Enable (
OE ) and Chip Enable ( CE ) controls which eliminate
bus contention issues.
