Instructions for Use

1. Power Supply:

   • Connect the Vcc pin to a power supply within the range of 2.5V to 5.5V.
   • Connect the GND pin to the ground.

2. Pin Configuration:

   • SI (Serial Input): Data input pin.
   • SO (Serial Output): Data output pin.
   • SCK (Serial Clock): Clock input pin.
   • CS (Chip Select): Active low chip select pin.
   • /WP (Write Protect): Active low write protect pin. Set high to enable writing.
   • Vpp (pin 8 NC): Not connected. Leave this pin unconnected.

3. Communication:

   • The 93C46CB6 uses the SPI protocol for communication.
   • Ensure that the SCK, SI, SO, and CS pins are properly connected to the corresponding pins on the microcontroller or host device.

4. Write Operation:

   • To write data, first ensure that the /WP pin is set high to disable write protection.
   • Assert the CS pin low to select the device.
   • Send the appropriate write command followed by the address and data.
   • Deassert the CS pin high to complete the write operation.
   • Wait for the write time (5 ms max) before performing another operation.

5. Read Operation:

   • Assert the CS pin low to select the device.
   • Send the appropriate read command followed by the address.
   • The device will output the data on the SO pin.
   • Deassert the CS pin high to complete the read operation.

6. Standby Mode:

   • To enter standby mode, deassert the CS pin high.
   • The device will consume minimal current (1 渭A max).

7. Data Retention:

   • The device guarantees data retention for at least 10 years under normal operating conditions.

8. Handling Precautions:

   • Handle the device with care to avoid static discharge.
   • Ensure that all connections are secure and within the specified voltage ranges to prevent damage.
