DESCRIPTION

The M28F512 Flash memory is a non-volatile

memory that may be erased electricallyat the chip

level and programmed by byte. It is organised as

64 Kbytes of 8 bits. It uses a command register

architecturetoselecttheoperatingmodesandthus

provides a simple microprocessor interface. The

device is offered in PDIP32 and PLCC32 pack-

ages.
