MC56F8122VFAE datasheet by Freescale Semiconductor

MC56F8122VFAE Frequently Asked Questions (FAQs)

• What is the maximum operating frequency of the MC56F8122VFAE?
  The maximum operating frequency of the MC56F8122VFAE is 60 MHz, but it can be overclocked to 80 MHz with reduced voltage and temperature range.
• How do I configure the internal clock source?
  The internal clock source can be configured using the Clock Management Unit (CMU) module. The CMU module allows you to select the clock source, divide the clock frequency, and enable/disable the clock output.
• What is the maximum amount of current that can be sourced/sunk by the GPIO pins?
  The maximum amount of current that can be sourced by the GPIO pins is 20 mA, and the maximum amount of current that can be sunk is 25 mA. However, it's recommended to limit the current to 10 mA to ensure reliable operation.
• How do I implement a watchdog timer on the MC56F8122VFAE?
  The MC56F8122VFAE has a built-in watchdog timer (WDOG) module that can be used to reset the microcontroller in case of a software fault. The WDOG module can be configured to generate a reset signal after a specified timeout period if the watchdog timer is not refreshed.
• What is the minimum voltage required for the MC56F8122VFAE to operate?
  The minimum voltage required for the MC56F8122VFAE to operate is 2.7V, but it's recommended to operate the device at a voltage of 3.0V or higher to ensure reliable operation.
