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.
