Description
The AT27C1024 is a low-power, high-performance 1,048,576 bit one-time program-
mable read only memory (OTP EPROM) organized 64K by 16 bits. It requires only
one 5V power supply in normal read mode operation. Any word can be accessed in
less than 45 ns, eliminating the need for speed reducing WAIT states. The by-16
organization make this part ideal for high-performance 16- and 32-bit microprocessor
systems.
