The Microchip Technology Inc. 27C256 is a CMOS
256K bit electrically Programmable Read Only Memory
(EPROM). The device is organized as 32K words by 8
bits (32K bytes). Accessing individual bytes from an
address transition or from power-up (chip enable pin
going low) is accomplished in less than 90 ns. This 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 reliability are requirements.
A complete family of packages is offered to provide the
most flexibility in applications. For surface mount applications,
PLCC, or SOIC packaging is available. Tape
and reel packaging is also available for PLCC or SOIC
packages.
