The Microchip Technology Inc. 27C128 is a CMOS128K bit (electrically) Programmable Read Only Memory.The device is organized as 16K words by 8 bits(16K bytes). Accessing individual bytes from anaddress transiTIon or from power-up (chip enable pingoing low) is accomplished in less than 120 ns. CMOSdesign and processing enables this part to be used insystems where reduced power consumpTIon and highreliability are requirements.A complete family of packagesis offered to provide the most flexibility in applicaTIons.For surface mount applicaTIons, PLCC, SOIC, orTSOP packaging is available. Tape and reel packagingis also available for PLCC or SOIC packages. UV erasableversions are also available.A complete family of packages is offered to provide themost flexibility in applications. For surface mount applications,PLCC or SOIC packaging is available. Tapeand reel packaging is also available for PLCC or SOICpackages.
