GENERAL DESCRIPTION
The Am27X010 is a factory programmed and tested
OTP EPROM. It is progra mmed after pac kaging prior to
final test. Every device is rigorously tested under AC
and DC operating conditions to your stable code. It is
organized as 1 28 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 alternativ e to O TP EPROMs and mask programmed ROMs.

Data can be accessed as fast as 55 ns, allowing
high-performance microprocessors to operate with reduced WAIT states. The device offers separate Output
Enable (OE#) and Chip Enable (CE#) 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 consumption is only 100 mW in active mode,
and 100 µW in standby mode.
