Description

The Microchip Technology Inc. 27C256 is a CMOS 256K bit electrically Programmable Read Only Memory (EPROM).  The device is organized as 32K words by 8bits (32K bytes).  Accessing individual bytes from an address transition or from power-up (chip enable pingoing low) is accomplished in less than 90 ns. 27C256 allows the most sophisticated micro processors 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 powerconsumption and reliability are requirements.

A complete family of packages is offered to provide the most flexibility in applications.  For surface mount appli-cations, PLCC, SOIC, VSOP or TSOP packaging isavailable.  Tape and reel packaging is also available for
