DESCRIPTION

The Microchip Technology Inc. 27C64 is a CMOS 64K

bit (electrically) Programmable Read Only Memory.

The device is organized as 8K words by 8 bits (8K

bytes). Accessing individual bytes from an address

transition or from power-up (chip enable pin going low)

is accomplished in less than 120 ns. CMOS design and

processing enables this part to be used in systems

where reduced power consumption and high 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.
