Instructions for Use

1. Power Supply:

   • Connect V_CC to the positive power supply (2.5V to 5.5V).
   • Connect GND to the ground.

2. Clock Input (SCLK):

   • Apply a clock signal to the SCLK pin. The frequency should be between 0 and 10 MHz.

3. Chip Select (CS):

   • Pull CS low to enable communication with the device.
   • When CS is high, the device is in standby mode.

4. Serial Data In (SI):

   • Send data to the device through the SI pin during write operations.

5. Serial Data Out (SO):

   • Read data from the device through the SO pin during read operations.

6. Write Protect (WP):

   • Connect WP to V_CC to disable write operations.
   • Connect WP to GND to enable write operations.

7. Write Enable (WEN):

   • Set WEN to low to enable write operations.
   • Set WEN to high to disable write operations.

8. Command Sequence:

   • Read Operation:
     • Assert CS low.
     • Send the read command (e.g., 0000 0001).
     • Send the address (9 bits).
     • The device will output the data on the SO pin.
     • Deassert CS to end the read operation.
   • Write Operation:
     • Assert CS low.
     • Send the write enable command (e.g., 0000 0110).
     • Send the address (9 bits).
     • Send the data to be written.
     • Deassert CS to end the write operation.
     • Wait for the write cycle time (4 ms max) before initiating another write operation.

9. Error Handling:

   • Ensure that the write protect pin (WP) is correctly configured to avoid accidental writes.
   • Monitor the status of the device to ensure successful completion of write operations.

10. Storage and Handling:

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