GENERAL DESCRIPTION
The Am27X040 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 512 Kwords by 8 bits per word and is
available in plastic dual in-line packages (PDIP), as
well as plastic leaded chip carrier (PLCC) packages.
ExpressROM 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 pro-
grammed ROMs.
Data can be accessed as fast as 90 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 100 mW in active mode,
and 100 µW in standby mode.
