Instructions for Using M27C256B12F1

  1. Power Supply:

    • Connect the VCC pin to a 4.5V to 5.5V power supply.
    • Connect the GND pin to ground.
  2. Addressing:

    • Apply the desired address to the address lines (A0-A17) to select the memory location.
    • Ensure that the address setup time (tAS) is met before the rising edge of the chip enable (CE) signal.
  3. Chip Enable (CE):

    • Set CE low to enable the device for read operations.
    • The chip enable hold time (tCH) must be maintained after the address is stable.
  4. Output Enable (OE):

    • Set OE low to enable the output drivers and allow data to be read from the selected memory location.
    • The output enable setup time (tOE) must be met before the rising edge of the chip enable (CE) signal.
  5. Data Output:

    • Data will be available on the data output lines (D0-D7) after the access time (tAA).
    • Ensure that the output enable hold time (tOH) is maintained to keep the data valid.
  6. Standby Mode:

    • To enter standby mode, set both CE and OE high. This will minimize power consumption.
  7. Timing Considerations:

    • Ensure all timing parameters (setup and hold times) are met to avoid data corruption or incorrect operation.
    • Use appropriate pull-up resistors on the output lines if driving high-impedance loads.
  8. Storage and Handling:

    • Store the device in a dry, static-free environment.
    • Handle with care to avoid damage to the pins and internal components.

By following these instructions, you can ensure reliable and efficient operation of the M27C256B12F1 EEPROM.
