... Any byte can be accessed in less than 45 ns, eliminating the need for speed reducing WAIT states on high-performance microprocessor systems. Atmel’s scaled CMOS technology provides low-active power consumption, and fast programming. Power consumption is typically only Active Mode and less than Standby. ...

... With 32K byte storage capability, the AT27C256R allows firmware to be stored reliably and to be accessed by the system without the delays of mass storage media. Atmel’s 27C256R has additional features to ensure high quality and efficient production use. The Rapid™ Program- ming Algorithm reduces the time required to program the part and guarantees reliable programming. Programming time is typically only 100 µ ...
