... Commercial and Industrial Temperature Ranges 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 ...

... OE) to eliminate bus contention in high-speed systems. With high density 256K word storage capability, the AT27C4096 allows firmware to be stored reliably and to be accessed by the system without the delays of mass storage media. Atmel’s AT27C4096 has additional features that ensure high quality and efficient production use ...
