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.

1. VCC must be applied simultaneously or before VPP, and removed simultaneously or after VPP.
2. VPP may be connected directly to VCC, except during programming. The supply current would then be the sum of ICC and
IPP.
