MCHC908QY4VDWE datasheet by Freescale Semiconductor

MCHC908QY4VDWE Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for this microcontroller?
  The MCHC908QY4VDWE can operate from -40°C to 105°C, with a maximum junction temperature of 150°C.
• How do I configure the internal oscillator for optimal performance?
  The internal oscillator can be configured using the OSCCLK and OSCSTEN bits in the OSCCTL register. For optimal performance, set OSCCLK to 00 (internal oscillator enabled) and OSCSTEN to 1 (oscillator stabilization enabled).
• What is the maximum current that can be sourced or sunk by the GPIO pins?
  The maximum current that can be sourced or sunk by the GPIO pins is 25 mA per pin, with a total current limit of 100 mA for all GPIO pins combined.
• How do I implement a watchdog timer on this microcontroller?
  The watchdog timer can be implemented using the COP (Computer Operating Properly) module. Configure the COPCTL register to set the watchdog timer period and enable the COP module.
• What is the minimum and maximum clock frequency that can be used with this microcontroller?
  The minimum clock frequency is 32 kHz (using the internal oscillator) and the maximum clock frequency is 20 MHz (using an external crystal oscillator).
