Instructions

1. Power Supply:

   • Connect VCC to the positive power supply (1.7V to 3.6V).
   • Connect GND to the ground.

2. SPI Interface:

   • SI (Serial Input): Data input from the master.
   • SCK (Serial Clock): Clock signal from the master.
   • CS (Chip Select): Active low signal to select the device.
   • SO (Serial Output): Data output to the master.
   • WP (Write Protect): Active low signal to prevent write operations.
   • HOLD (Hold): Active low signal to hold the device in a paused state.

3. Initialization:

   • Ensure CS is high to keep the device deselected.
   • Set WP high to allow write operations.
   • Set HOLD high to ensure normal operation.

4. Reading Data:

   • Pull CS low to select the device.
   • Send the read command (e.g., 0x03).
   • Send the address of the memory location to be read.
   • The device will send the data byte on SO during the subsequent clock cycles.
   • Pull CS high to deselect the device.

5. Writing Data:

   • Pull CS low to select the device.
   • Send the write enable command (e.g., 0x06).
   • Send the write command (e.g., 0x02).
   • Send the address of the memory location to be written.
   • Send the data byte to be written.
   • Wait for the programming time (5 ms max) before performing another write or read operation.
   • Pull CS high to deselect the device.

6. Erasing the Chip:

   • Pull CS low to select the device.
   • Send the write enable command (e.g., 0x06).
   • Send the chip erase command (e.g., 0xC7).
   • Wait for the erase time (10 ms max) before performing another write or read operation.
   • Pull CS high to deselect the device.

7. Status Register:

   • To read the status register:
     • Pull CS low to select the device.
     • Send the read status register command (e.g., 0x05).
     • The device will send the status byte on SO.
     • Pull CS high to deselect the device.
   • To write to the status register:
     • Pull CS low to select the device.
     • Send the write enable command (e.g., 0x06).
     • Send the write status register command (e.g., 0x01).
     • Send the new status byte.
     • Pull CS high to deselect the device.

8. Write Protection:

   • Set WP low to prevent any write or erase operations.
   • Set WP high to allow write and erase operations.

9. Hold Function:

   • Set HOLD low to pause any ongoing SPI transactions.
   • Set HOLD high to resume normal operation.

10. Storage:

    • Store the device in a dry, cool place to ensure data retention.
    • Avoid exposing the device to extreme temperatures or humidity.
