GENERAL DESCRIPTION

The Am27C020 is a 2 Megabit, ultraviolet erasable pro-

grammable read-only memory. It is organized as 256

Kwords by 8 bits per word, operates from a single +5 V

supply, has a static standby mode, and features fast

single address location programming. Products are

available in windowed ceramic DIP packages, as well

as plastic one time programmable (OTP) PDIP and

PLCC 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 100 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 a typical programming time of 32 seconds.

Data can be typically accessed in less than 55 ns, al-

lowing high-performance microprocessors to operate

without any WAIT states. The device offers separate

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