MSP430G2744IYFFT datasheet by Texas Instruments

MSP430G2744IYFFT 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 MSP430G2744IYFFT for low-power operation?
  To configure the MSP430G2744IYFFT 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 3 (LPM3) or Low Power Mode 4 (LPM4) modes. 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 to prevent damage to the device.
• How do I implement a watchdog timer on the MSP430G2744IYFFT?
  The MSP430G2744IYFFT has a built-in Watchdog Timer (WDT) module that can be configured to reset the device if it fails to respond within a specified time period. To implement a watchdog timer, you need to configure the WDT module, set the watchdog timer interval, and periodically reset the watchdog timer using the WDT reset signal.
• What is the minimum and maximum operating temperature range for the MSP430G2744IYFFT?
  The minimum operating temperature range for the MSP430G2744IYFFT is -40°C, and the maximum operating temperature range is 85°C. However, the device can be operated at temperatures up to 105°C for short periods of time, but this may affect its reliability and lifespan.
