MSP430F1132IDWR datasheet by Texas Instruments

MSP430F1132IDWR Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that can be used with the internal oscillator?
  The maximum clock frequency that can be used with the internal oscillator is 8 MHz. However, it's recommended to use a clock frequency of 4 MHz or less to ensure reliable operation.
• How do I configure the MSP430F1132IDWR to use an external crystal oscillator?
  To configure the MSP430F1132IDWR to use an external crystal oscillator, you need to connect the crystal to the XIN and XOUT pins, and then configure the UCSCTL6 register to select the external crystal oscillator as the clock source.
• What is the minimum voltage required for the MSP430F1132IDWR to operate?
  The minimum voltage required for the MSP430F1132IDWR to operate is 1.8V. However, it's recommended to use a voltage of 2.2V or higher to ensure reliable operation.
• How do I use the built-in UART module on the MSP430F1132IDWR?
  To use the built-in UART module on the MSP430F1132IDWR, you need to configure the UCAxCTL0 and UCAxCTL1 registers to set the baud rate, data bits, and stop bits. You also need to enable the UART module by setting the UCAxCTL0.UCAEN bit.
• What is the maximum current that can be sourced or sunk by the GPIO pins?
  The maximum current that can be sourced or sunk by the GPIO pins on the MSP430F1132IDWR is 4 mA. However, it's recommended to limit the current to 2 mA or less to ensure reliable operation.
