Description
The AT27C2048 is a low-power, high performance 2,097,152-bit one-time program-
mable read only memory (OTP EPROM) organized 128K 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.
