GENERAL DESCRIPTION
The Am27X64 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 8 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 55 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.
