MCF5272VF66 datasheet by Freescale Semiconductor

MCF5272VF66 Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for the MCF5272VF66?
  The MCF5272VF66 can operate from -40°C to 105°C (ambient temperature) and up to 125°C (junction temperature) with some limitations on the clock frequency and voltage supply.
• How do I configure the internal clock source for the MCF5272VF66?
  The internal clock source can be configured using the Clock Generation Module (CGM) registers. The CGM provides a flexible clock generation system that allows the user to select from various clock sources, including the internal Fast Internal RC (FIRC) oscillator, the Slow Internal RC (SIRC) oscillator, and external clock sources.
• What is the maximum amount of current that the MCF5272VF66 can source or sink on its GPIO pins?
  The MCF5272VF66 can source up to 4 mA and sink up to 8 mA on its GPIO pins. However, the total current sourced or sunk by all GPIO pins should not exceed 100 mA to prevent overheating and ensure reliable operation.
• How do I implement a watchdog timer on the MCF5272VF66?
  The MCF5272VF66 has a built-in watchdog timer module that can be enabled and configured using the Watchdog Timer (WDT) registers. The watchdog timer can be used to reset the microcontroller in case of a software fault or hang-up.
• What is the maximum data transfer rate for the MCF5272VF66's USB interface?
  The MCF5272VF66's USB interface supports full-speed data transfer rates of up to 12 Mbps.
