DESCRIPTION

The M28F101 FLASH Memory is a non-volatile memory which may be erased electrically at the

chip level and programmed byte-by-byte. It is or ganised as 128K bytes of 8 bits.It uses a command register architecture to select the operating modes and thus provides a simple microprocessor interface. The M28F101 FLASH Memory is suitable for applications where the memory has to be reprogrammed in the equipment. The access time of 70ns makes the device suitable for use in high speed microprocessor systems.
