M28F256 256 Kbit Flash Memory

The M28F256 Flash memory is a non-volatile memory that may be erased electrically at the chip level and programmed by byte. It is organised as 32 Kbytes of 8 bits. It uses a command register architectureto select the operatingmodes and thus provides a simple microprocessor interface. The device is o.
