Am27X040

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 programmed ROMs.

Data can be accessed as fast as 90 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 W in standby mode.
