IP82C55A Frequently Asked Questions (FAQs)

  • The IP82C55A can operate at a maximum clock frequency of 24 MHz.
  • The IP82C55A has a built-in watchdog timer that can be enabled by setting the WDTEN bit in the WDCR register. The watchdog timer can be configured to timeout after 16, 32, 64, or 128 clock cycles.
  • No, the IP82C55A is a 3.3V device and is not compatible with 5V systems. Applying 5V to the device can cause damage or malfunction.
  • The IP82C55A can be reset by asserting the RESET pin low for at least 2 clock cycles. The device will also reset automatically when power is applied or when the watchdog timer times out.
  • The IP82C55A can sink or source up to 4mA of current on its I/O pins.
