HT7463B Frequently Asked Questions (FAQs)

  • The HT7463B can operate at a maximum clock frequency of 20 MHz, but it is recommended to operate at 16 MHz or lower for stable operation.
  • The oscillator circuit for the HT7463B requires a 10kΩ to 20kΩ resistor and a 10pF to 30pF capacitor connected between the OSC1 and OSC2 pins. The exact values may vary depending on the crystal frequency and load capacitance.
  • The HT7463B can operate at a minimum voltage of 2.2V, but it is recommended to operate at 2.5V or higher for stable operation.
  • The HT7463B can be programmed using a serial programmer or an in-circuit programmer. The programming protocol is based on the SPI protocol, and the device can be programmed using a programming software such as HT-IDE or a third-party tool.
  • The HT7463B can sink or source a maximum current of 20mA per I/O pin, but the total current should not exceed 100mA for the entire device.
