MC908JL16CDWE datasheet by Freescale Semiconductor

MC908JL16CDWE Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for this microcontroller?
  The MC908JL16CDWE can operate from -40°C to 105°C, but it's recommended to operate within -20°C to 85°C for optimal performance.
• How do I configure the clock source for the MCU?
  The clock source can be configured using the Clock Generator Module (CGM) registers. You can choose between internal clock sources (e.g., internal RC oscillator) or external clock sources (e.g., crystal oscillator). Refer to the MC908JL16CDWE reference manual for specific register settings.
• What is the maximum current consumption of the MCU?
  The maximum current consumption of the MC908JL16CDWE depends on the operating mode and clock frequency. In active mode, the maximum current consumption is around 10mA at 16MHz clock frequency. In sleep mode, the current consumption is typically in the range of 10-50uA.
• How do I implement a watchdog timer in this MCU?
  The MC908JL16CDWE has a built-in watchdog timer (COP) that can be enabled and configured using the COP control register. You can set the watchdog timer period and enable it to reset the MCU in case of a fault or hang-up.
• Can I use the MCU's internal flash memory for data storage?
  Yes, the MC908JL16CDWE has 16KB of internal flash memory that can be used for data storage. However, keep in mind that the flash memory has a limited number of erase cycles (around 10,000), so it's recommended to use it for storing configuration data or firmware updates rather than frequently changing data.
