MSP430F6435IPZR datasheet by Texas Instruments

MSP430F6435IPZR Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for the MSP430F6435IPZR?
  The maximum operating temperature range for the MSP430F6435IPZR is -40°C to 85°C, but it can be extended to -40°C to 105°C with some limitations on the clock frequency and supply voltage.
• How do I configure the MSP430F6435IPZR for low-power operation?
  To configure the MSP430F6435IPZR 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. You can also use the Dynamic Voltage Scaling (DVS) feature to reduce the supply voltage.
• 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 of the MSP430F6435IPZR is 4mA per pin, but it's recommended to limit the current to 2mA per pin to ensure reliable operation.
• How do I implement a watchdog timer on the MSP430F6435IPZR?
  The MSP430F6435IPZR has a built-in Watchdog Timer (WDT) module that can be configured to reset the device if it doesn't receive a reset signal within a specified time period. You can configure the WDT using the WDTCTL register and enable it using the WDTIE bit in the SFRIE1 register.
• What is the maximum frequency of the internal oscillator on the MSP430F6435IPZR?
  The maximum frequency of the internal oscillator on the MSP430F6435IPZR is 16MHz, but it can be divided down to lower frequencies using the FLLUNLOCK and FLLD bits in the FLL_CTL0 register.
