GENERAL DESCRIPTION
The EN27LV010/EN27LV010B is a low-voltage, low-power 1-Megabit, 3.3V one-time-
programmable (OTP) read-only memory (EPROM). Organized into 128K 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 90ns. The EN27LV010/EN27LV010B has separate Output
Enable ( OE ) and Chip Enable ( CE ) controls which eliminate bus contention issues. The
EN27LV010 has a Vcc tolerance range of 3.0V to 3.6 V, making it suitable for use in systems that
have regulated power supplies. The EN27LV010B has a Vcc tolerance range of 2.7 V to 3.6V,
making it an ideal device for battery operated systems.
