The recommended crystal oscillator frequency for the MC9328MX21CJM is 16 MHz or 24 MHz, depending on the specific application and clock speed requirements.
The IVR on the MC9328MX21CJM can be configured through the Power Management Controller (PMC) registers. The PMC registers control the IVR output voltage, mode, and other parameters. Refer to the MC9328MX21CJM reference manual for detailed information on IVR configuration.
The maximum operating temperature range for the MC9328MX21CJM is -40°C to 105°C (industrial temperature range). However, the device can also be operated at extended temperatures with reduced performance and reliability.
The MC9328MX21CJM has a built-in watchdog timer (WDT) that can be enabled and configured through the WDT registers. The WDT can be used to reset the device in case of a software or hardware fault. Refer to the MC9328MX21CJM reference manual for detailed information on WDT configuration and usage.
The power consumption characteristics of the MC9328MX21CJM depend on the operating frequency, voltage, and mode. In active mode, the device typically consumes around 150-200 mA at 3.3V and 100 MHz. In sleep mode, the power consumption can be reduced to around 10-20 mA. Refer to the MC9328MX21CJM datasheet for detailed power consumption specifications.
