The maximum clock frequency for the MSP430F1610 is 8 MHz, but it can be overclocked up to 16 MHz with reduced voltage and temperature range.
To use an external crystal oscillator, set the XT2OFF bit in the FLLUNLOCK register to 0, and configure the XT2 pins as inputs. Then, connect the crystal oscillator to the XT2 pins and set the MCLK frequency to the desired value using the CSCTL registers.
The minimum voltage required for the MSP430F1610 to operate is 1.8V, but it can operate down to 1.6V with reduced frequency and performance.
The built-in temperature sensor on the MSP430F1610 is a 10-bit analog-to-digital converter (ADC) that can be accessed through the ADC10 module. Configure the ADC10 module to read the temperature sensor, and then use the ADC10MEM register to read the temperature value.
Yes, the MSP430F1610 can operate with a 3.3V power supply, but it may require additional external components to regulate the voltage and ensure reliable operation.
