DESCRIPTION
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.
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.

1.2 Read Mode
(See Timing Diagrams and AC Characteristics)
Read Mode is accessed when
a) the CE pin is low to power up (enable) the chip
b) the OE pin is low to gate the data to the output
pins
For Read operations, if the addresses are stable, the
address access time (tACC) is equal to the delay from
CE to output (tCE). Data is transferred to the output
after a delay from the falling edge of OE (tOE).
