MSP430F417CY datasheet by Texas Instruments

MSP430F417CY Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that can be used with the MSP430F417CY?
  The maximum clock frequency for the MSP430F417CY is 16 MHz, but it can be overclocked up to 20 MHz with reduced voltage and temperature ranges.
• How do I configure the MSP430F417CY to use an external crystal oscillator?
  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 CSCTLx registers.
• What is the minimum voltage required for the MSP430F417CY to operate?
  The minimum voltage required for the MSP430F417CY to operate is 1.8V, but it can operate down to 1.6V with reduced performance and functionality.
• How do I use the built-in temperature sensor on the MSP430F417CY?
  The built-in temperature sensor on the MSP430F417CY 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.
• Can I use the MSP430F417CY with a 5V power supply?
  No, the MSP430F417CY is not 5V tolerant and should not be used with a 5V power supply. The maximum recommended voltage is 3.6V.
