DESCRIPTION

The Microchip Technology Inc. 27C256 is a CMOS

256K bit electrically Programmable Read Only Memory

(EPROM). The device is organized as 32K words by 8

bits (32K bytes). Accessing individual bytes from an

address transition or from power-up (chip enable pin

going low) is accomplished in less than 90 ns. This very

high speed device allows the most sophisticated micro-

processors to run at full speed without the need for

WAIT states. CMOS design and processing enables

this part to be used in systems where reduced power

consumption and reliability are requirements.

A complete family of packages is offered to provide the

most flexibility in applications. For surface mount appli-

cations, PLCC, or SOIC packaging is available. Tape

and reel packaging is also available for PLCC or SOIC

packages.
