MSP430F5151IRSBR datasheet by Texas Instruments

MSP430F5151IRSBR 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 16 MHz. However, it's recommended to use a clock frequency of 12 MHz or less to ensure reliable operation.
• How do I configure the MSP430F5151IRSBR for low-power operation?
  To configure the MSP430F5151IRSBR for low-power operation, you can use the Power Management Module (PMM) to select the lowest possible clock frequency, disable unused peripherals, and use the Low Power Mode (LPM) feature. Additionally, you can use the Dynamic Voltage Scaling (DVS) feature to reduce the voltage supply to the core and peripherals.
• 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 is 4 mA. However, it's recommended to limit the current to 2 mA or less to ensure reliable operation and prevent damage to the device.
• How do I use the Universal Serial Communication Interface (USCI) module for UART, SPI, or I2C communication?
  The USCI module can be configured for UART, SPI, or I2C communication by setting the appropriate registers and using the corresponding APIs in the device driver library. The USCI module can operate in master or slave mode, and supports various clock frequencies and data formats.
• What is the purpose of the JTAG interface, and how do I use it for debugging?
  The JTAG interface is a debugging interface that allows you to connect a debugger or emulator to the device for debugging and testing purposes. You can use the JTAG interface to access the device's memory, registers, and peripherals, and to set breakpoints and inspect variables.
