GENERAL DESCRIPTION
The EN27C512 is a low-power 512Kbit, 5V-only one-time-programmable (OTP) read-only
memory (EPROM). Organized into 64K words with 8 bits per word, it features QuikRite
TM
single-
address location programming, typically at 20
μ
s per byte. Any byte can be accessed in less than
45ns, eliminating the need for WAIT states in high-performance microprocessor systems. The
EN27C512 has separate Output Enable (
OE
) and Chip Enable (
CE
) controls which eliminate
bus contention issues.
