Instructions for RTC-72421A
Power Supply Connection:
- Connect the supply voltage (Vcc) between 1.6V and 5.5V to pin 1.
- Ground (GND) should be connected to pin 5.
Clock Output Configuration:
- The 32.768 kHz output is available on pin 2 (XOUT). Ensure that the load capacitance is set to 6 pF for optimal performance.
Crystal Connection:
- Connect an external 32.768 kHz crystal between pins 3 (X1) and 4 (X2).
Operating Temperature:
- The device is designed to operate within a temperature range of -40°C to +85°C. Ensure that the operating environment stays within these limits to maintain accuracy.
Current Consumption:
- The device consumes approximately 230 nA in active mode, making it suitable for low-power applications.
Mounting Orientation:
- Follow standard mounting procedures for SOT-23-5 packages. Ensure proper orientation to avoid damage or malfunction.
Handling Precautions:
- Handle with care to avoid electrostatic discharge (ESD), which can damage the component. Use appropriate ESD protection measures during handling and installation.
