Instructions for Using AT28C16E-15PC

1. Power Supply:

   • Ensure the supply voltage (Vcc) is within the range of 4.5V to 5.5V.
   • Connect the ground (GND) pin to the system ground.

2. Standby Mode:

   • To minimize power consumption, set the chip enable (CE) and output enable (OE) pins high, and the write enable (WE) pin low.

3. Active Mode:

   • For read operations, set CE and OE low, and WE high.
   • For write operations, set CE, OE, and WE low.

4. Timing Considerations:

   • Ensure that all timing parameters are met to avoid data corruption or incorrect operation.
   • Address setup time (tAS) must be at least 20ns before the falling edge of the CE signal.
   • Data hold time (tDH) must be at least 10ns after the falling edge of the CE signal.

5. Data and Address Lines:

   • Connect the address lines (A0-A13) to the appropriate address bus.
   • Connect the data lines (D0-D7) to the data bus.

6. Write Operation:

   • To write data, ensure the write cycle time (tWC) is at least 10μs.
   • The write enable (WE) signal must be held low for the duration of the write cycle.

7. Output Enable:

   • The output enable (OE) signal controls the output buffers. Set OE low to enable data output.

8. Chip Enable:

   • The chip enable (CE) signal selects the device. Set CE low to select the device for read or write operations.

9. Handling:

   • Handle the device with care to avoid electrostatic discharge (ESD) damage.
   • Use proper ESD protection measures during handling and installation.

10. Storage:

    • Store the device in a dry, cool place to prevent moisture damage.
    • Follow the recommended storage conditions provided by the manufacturer.
