GENERAL DESCRIPTION

The Am27X512 is a factory programmed and tested

OTP EPROM. It is programmed after packaging prior to

final test. Every device is rigorously tested under AC

and DC operating conditions to your stable code. It is

organized as 64 Kwords by 8 bits per word and is avail-

able in plastic dual in-line packages (PDIP), as well as

plastic leaded chip carrier (PLCC) packages. Express-

ROM devices provide a board-ready memory solution

for medium to high volume codes with short leadtimes.

This offers manufacturers a cost-effective and flexible

alternative to OTP EPROMs and mask programmed

ROMs.

Data can be accessed as fast as 70 ns, allowing

high-performance microprocessors to operate with re-

duced WAIT states. The device offers separate Output

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

eliminating bus contention in a multiple bus micropro-

cessor system.

AMD’s CMOS process technology provides high

speed, low power, and high noise immunity. Typical

power consumption is only 80 mW in active mode, and

100 µW in standby mode.
