IQ82C55AZ96 Frequently Asked Questions (FAQs)

  • The recommended operating voltage range for IQ82C55AZ96 is 4.5V to 5.5V, with a typical voltage of 5V.
  • To configure the IQ82C55AZ96 for I2C mode, set the Mode pin (pin 31) to LOW, and ensure the SCL and SDA pins are connected to the I2C bus. Also, configure the device address using the A0, A1, and A2 pins.
  • The IQ82C55AZ96 supports clock frequencies up to 24 MHz in I2C mode and up to 10 MHz in SPI mode.
  • The IQ82C55AZ96 generates interrupt signals on the INT pin (pin 30) when an event occurs, such as a transmission completion or a receive buffer full condition. The interrupt signal can be connected to an interrupt controller or a microcontroller's interrupt input to handle the event.
  • The Reset pin (pin 29) is an active-low input that resets the IQ82C55AZ96 when pulled LOW. It is recommended to connect this pin to a pull-up resistor and a capacitor to ensure a clean reset signal.
