The maximum clock frequency of the MSP430F47187IPZ is 8 MHz.
To use an external clock source, connect the external clock signal to the XIN pin and configure the UCSCTL6 register to select the external clock source.
The maximum current consumption of the MSP430F47187IPZ is approximately 2.1 mA at 3V and 8 MHz.
The built-in temperature sensor is connected to ADC channel 10. Configure the ADC to read the temperature sensor by setting the ADCCTL0 register to 0x010C and then read the temperature value from the ADCMEM0 register.
No, the MSP430F47187IPZ is only rated for operation up to 3.6V. Using a 5V power supply may damage the device.
