DESCRIPTION
The Microchip Technology Inc. 27C512A is a CMOS
512K bit electrically Programmable Read Only Memory
(EPROM). The device is organized into 64K words by
8 bits (64K bytes). Accessing individual bytes from an
address transition or from power-up (chip enable pin
going low) is accomplished in less than 90 ns.
very high speed device allows the most sophisticated
microprocessors 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 high reliability are require-
ments.
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 or
reel packaging is also available for PLCC or SOIC
packages.
