GENERAL DESCRIPTION

The EN27LV512 / EN27LV512B is a low voltage, low-power 512K bit, 3.3V one-time-

programmable (OTP) read-only memory (EPROM). Organized into 64K 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 EN27LV512 / EN27LV512B has separate Output

Enable ( OE ) and Chip Enable ( CE ) controls which eliminate bus contention issues. The

EN27LV512 has a Vcc tolerance range of 3.0V to 3.6V, making it suitable for use in systems that

have regulated power supplies. The EN27LV512B has a Vcc tolerance range of 2.7V to 3.6V,

making it ideally suited for battery operated systems.
