MSP430F1481IPMR datasheet by Texas Instruments

MSP430F1481IPMR Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that can be used with the MSP430F1481IPMR?
  The maximum clock frequency for the MSP430F1481IPMR is 16 MHz, but it can be overclocked up to 20 MHz with reduced voltage and temperature range.
• How do I configure the MSP430F1481IPMR for low power consumption?
  To configure the MSP430F1481IPMR for low power consumption, use the low-power modes (LPM0-LPM4) and adjust the clock frequency, disable unused peripherals, and use the built-in brown-out reset (BOR) and power-on reset (POR) features.
• Can I use the MSP430F1481IPMR with a 3.3V power supply?
  Yes, the MSP430F1481IPMR can operate with a 3.3V power supply, but the maximum clock frequency is limited to 12 MHz at this voltage. For 16 MHz operation, a 2.2V to 3.6V power supply is required.
• How do I implement a watchdog timer on the MSP430F1481IPMR?
  The MSP430F1481IPMR has a built-in watchdog timer (WDT) that can be enabled and configured using the WDTCTL register. The WDT can be set to timeout periods ranging from 512 to 8192 clock cycles.
• Can I use the MSP430F1481IPMR with an external crystal oscillator?
  Yes, the MSP430F1481IPMR can be used with an external crystal oscillator. The device has an internal oscillator that can be bypassed to use an external crystal oscillator, which can provide a more accurate clock signal.
