GENERAL DESCRIPTION

The Am27C020 is a 2 Mbit, ultraviolet erasable program-

mable read-only memory. It is organized as 256K words

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

has a static standby mode, and features fast single ad-

dress location programming. Products are available in

windowed ceramic DIP packages, as well as plastic

one-time programmable (OTP) including TSOP, PLCC,

and PDIP.

controls, thus eliminating bus contention in a multiple

bus microprocessor system.

AMD’s CMOS process technology provides high speed,

low power, and high noise immunity. Typical power con-

sumption 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 Am27C020 supports AMD’s Flashrite

programming algorithm (100 µs pulses) resulting in typ-

ical programming times of 32 seconds.

Typically, any byte can be accessed in less than 70 ns,

allowing operation with high-performance microproces-

sors without any WAIT states. The Am27C020 offers

separate Output Enable (OE) and Chip Enable (CE)
