DESCRIPTION
The M28F512 Flash memory is a non-volatile
memory that may be erased electrically at the chip
level and programmed by byte. It is organised as
64 Kbytes of 8 bits. It uses a command register
architectureto select the operatingmodes and thus
provides a simple microprocessor interface. The
device is offered in PDIP32 and PLCC32 pack-
ages.
