MSP430F1111AIPW datasheet by Texas Instruments

MSP430F1111AIPW Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that can be used with the MSP430F1111AIPW?
  The maximum clock frequency for the MSP430F1111AIPW is 8 MHz, but it can be overclocked up to 16 MHz with reduced voltage and temperature range.
• How do I configure the MSP430F1111AIPW 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 MSP430F1111AIPW to operate?
  The minimum voltage required for the MSP430F1111AIPW 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 UART module on the MSP430F1111AIPW?
  To use the built-in UART module, configure the UCAxCTL0 register to select the UART mode, set the baud rate using the UCAxBR0 and UCAxBR1 registers, and use the UCAxTXBUF and UCAxRXBUF registers to transmit and receive data.
• Can I use the MSP430F1111AIPW with a 5V power supply?
  No, the MSP430F1111AIPW is not 5V tolerant and should only be used with a power supply between 1.8V and 3.6V. Using a 5V power supply can damage the device.
