MSP430F2131IRGET datasheet by Texas Instruments

MSP430F2131IRGET Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that can be used with the MSP430F2131IRGET?
  The maximum clock frequency for the MSP430F2131IRGET is 16 MHz, but it can be overclocked up to 20 MHz with reduced voltage and temperature range.
• How do I configure the MSP430F2131IRGET to use an external crystal oscillator?
  To use an external crystal oscillator, connect the crystal to the XIN and XOUT pins, and configure the UCSCTL6 register to select the external crystal oscillator as the clock source.
• What is the minimum voltage required for the MSP430F2131IRGET to operate?
  The minimum voltage required for the MSP430F2131IRGET 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 MSP430F2131IRGET?
  The built-in temperature sensor on the MSP430F2131IRGET is a 10-bit analog-to-digital converter (ADC) that can be accessed through the ADC10 module. The temperature sensor is connected to ADC channel A10, and the temperature value can be read using the ADC10MEM register.
• What is the maximum current that can be sourced or sunk by the GPIO pins on the MSP430F2131IRGET?
  The maximum current that can be sourced or sunk by the GPIO pins on the MSP430F2131IRGET is 4mA, but this can be increased to 8mA by using the Port Pn pull-up/pull-down resistors.
