DESCRIPTION

12
The Microchip Technology Inc. 27C128 is a CMOS
128K bit (electrically) Programmable Read Only Mem-
ory. The device is organized as 16K words by 8 bits
(16K 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 pack-
ages is offered to provide the most flexibility in applica-
tions. For surface mount applications, PLCC, SOIC, or
TSOP packaging is available. Tape and reel packaging
is also available for PLCC or SOIC packages. UV eras-
able versions are also available.
