GENERAL DESCRIPTION

The Am27C64 is a 64-Kbit ultraviolet erasable program-

mable read-only memory. It is organized as 8K words 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 win-

dowed ceramic DIP packages as well as plastic one

time programmable (OTP) PDIP, and PLCC packages.

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 80 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 Am27C64 supports AMD’s Flashrite

programming algorithm (100 µs pulses) resulting in a

typical programming time of 1 second.

Typically, any byte can be accessed in less than 45 ns,

allowing operation with high-performance microproces-

sors without any WAIT states. The Am27C64 offers

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