GENERAL DESCRIPTION

The Am27C040 is a 4 Mbit ultraviolet erasable pro-

grammable read-only memory. It is organized as 512K

bytes, operates from a single +5 V supply, has a static

standby mode, and features fast single address loca-

tion programming. The device is available in windowed

ceramic DIP packages and plastic one-time program-

mable (OTP) packages.

thus eliminating bus contention in a multiple bus micro-

processor system.

AMD’s CMOS process technology provides high

speed, low power, and high noise immunity. Typical

power consumption is only 100 mW in active mode,

and 50 µW in standby mode.

All signals are TTL levels, including programming sig-

nals. Bit locations may be programmed singly, in

blocks, or at random. The device supports AMD’s

Flashrite programming algorithm (100 µs pulses) re-

sulting in typical programming time of 1 minute.

Data can be typically accessed in less than 90 ns, al-

lowing high-performance microprocessors to operate

without any WAIT states. The device offers separate

Output Enable (OE#) and Chip Enable (CE#) controls,
