The maximum clock frequency of the MSP430F2131IPWR is 16 MHz.
To configure the MSP430F2131IPWR for low power consumption, use the low-power modes (LPM3 or LPM4) and adjust the clock frequency, disable unnecessary peripherals, and use the built-in brown-out reset (BOR) to reduce power consumption.
Yes, the MSP430F2131IPWR can operate with a 3.3V power supply, but it is recommended to use a 2.2V to 3.6V power supply for optimal performance.
The MSP430F2131IPWR can be programmed using the Texas Instruments Code Composer Studio (CCS) or IAR Embedded Workbench, and can be flashed using the Spy-Bi-Wire (SBW) or Joint Test Action Group (JTAG) interface.
The maximum current that the MSP430F2131IPWR can source or sink is 4 mA per I/O pin, with a total current limit of 30 mA for all I/O pins combined.
