Instructions for PCF80C31BH-3/12P:

1. Supply Voltage (VDD):

   • Ensure the supply voltage is within the operating range of 2.0V to 5.5V to prevent damage to the device.

2. Frequency Selection:

   • The device can operate at two frequency ranges:
     • Low Frequency: 32 kHz to 128 kHz
     • High Frequency: 192 kHz to 384 kHz
   • Choose the appropriate frequency based on application requirements.

3. Power Consumption:

   • At 32.768 kHz, the typical power consumption is 0.4 渭A.
   • At 192 kHz, the typical power consumption increases to 1.2 渭A.

4. Oscillator Load Capacitance:

   • Use load capacitors with values between 6 pF and 12 pF for optimal performance.

5. Operating and Storage Temperature:

   • Operate the device within the temperature range of -40掳C to +85掳C.
   • Store the device within the temperature range of -55掳C to +125掳C.

6. Installation:

   • Handle with care to avoid electrostatic discharge (ESD).
   • Follow standard surface mount technology (SMT) procedures for installation.

7. Testing:

   • Verify the output frequency using a frequency counter or oscilloscope after installation.
   • Ensure the supply voltage and load capacitance are correctly set before testing.
