Am27X256

The Am27X256 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 32 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. Express- ROM devices Am27X256 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 reduced WAIT states. Am27X256 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 80 mW in active mode, and 100 W in standby mode.
