Instructions for Use

1. Power Supply:

   • Connect VCC to a stable power supply within the operating range (1.7 V to 3.6 V).
   • Connect GND to the ground.

2. SPI Interface:

   • CS (Chip Select): Active low. When low, the device is selected and can communicate.
   • SCK (Serial Clock): Input clock signal for synchronization.
   • MOSI (Master Out Slave In): Data input from the master to the device.
   • MISO (Master In Slave Out): Data output from the device to the master.
   • WP (Write Protect): Active low. When low, write operations are inhibited.
   • HOLD (Hold): Active low. When low, it pauses ongoing operations.

3. Initialization:

   • Ensure that the device is powered on and CS is high.
   • Set the WP pin to high to allow write operations.
   • Set the HOLD pin to high to prevent pausing operations.

4. Reading Data:

   • Pull CS low to select the device.
   • Send the read command (e.g., 0x03) followed by the address of the memory location.
   • The device will respond with the data at the specified address.
   • 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) followed by the address and data to be written.
   • Wait for the write cycle to complete (typically 70 ns to 150 ns).
   • Pull CS high to deselect the device.

6. Data Retention:

   • Ensure that the device is not exposed to temperatures exceeding 85°C for extended periods to maintain data retention for up to 10 years.

7. Endurance:

   • The device supports unlimited reads and up to 1 million write/erase cycles. Avoid excessive write operations to extend the lifespan.

8. Handling:

   • Handle the device with care to avoid static discharge, which can damage the internal circuitry.
   • Store the device in a dry, cool environment when not in use.
