Instructions for Use:
Power Supply Connection:
- Connect the Vcc pin to a power supply within the specified range (1.6V to 3.6V).
- Ensure the GND pin is connected to ground.
Communication Setup:
- The device uses SPI protocol for data transfer.
- Connect the following pins to your microcontroller or SPI master device:
- MOSI (Master Out Slave In)
- MISO (Master In Slave Out)
- SCK (Serial Clock)
- CS (Chip Select)
Initialization:
- Before performing any read/write operations, ensure the device is properly initialized by setting the CS pin low to select the device.
Read/Write Operations:
- For write operations, send the appropriate command followed by the address and data bytes.
- For read operations, send the read command and address, then clock out the data from the MISO line.
Standby Mode:
- To enter standby mode, set the CS pin high, which minimizes current consumption.
Handling Precautions:
- Avoid exceeding the maximum operating temperature to ensure data retention.
- Ensure stable power supply and proper grounding to prevent data corruption.
Storage:
- Store in a dry environment away from direct sunlight and extreme temperatures to maintain reliability.
