... It uses a command register architecture to select the operating modes and thus provides a simple microprocessor inter- face. The M28F101 FLASH Memory is suitable for applications where the memory has to be repro- grammed in the equipment. The access time of 70ns makes the device suitable for use in high speed microprocessor systems ...

... The Electronic Signature Mode is set-up by writing 90h to the command register. The following read cycles, with address inputs 00000h or 00001h, output the manufacturer or device type codes. The command is terminated by writing an- other valid command to the command register (for example Reset). M28F101 -100 Unit =5V 10% CC EPROM Interface ...
