  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. 27C512A 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 requirements.

   A complete family of packages is offered to provide the most flexibility in 27C512A applications. For surface mount applications, PLCC, VSOP, TSOP or SOIC packaging is available. Tape or reel packaging is also available for PLCC or SOIC packages.
