Description

The AT27C4096 is a low-power, high-performance 4,194,304-bit one-time program-

mable read only memory (OTP EPROM) organized 256K by 16 bits. It requires a sin-

gle 5V power supply in normal read mode operation. Any word can be accessed in

less than 55 ns, eliminating the need for speed-reducing WAIT states. The by-16

organization makes this part ideal for high-performance 16- and 32-bit microprocessor

systems.
