The recommended crystal oscillator frequency for the MSP430F2274IYFFT is between 32.768 kHz and 16 MHz, with a typical frequency of 1 MHz, 2 MHz, 4 MHz, or 8 MHz.
To configure the MSP430F2274IYFFT for low-power operation, 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, use the Dynamic Voltage Scaling (DVS) feature to reduce the voltage supply to the core and peripherals.
The maximum current consumption of the MSP430F2274IYFFT depends on the operating frequency, voltage supply, and peripherals used. According to the datasheet, the maximum current consumption is approximately 15 mA at 3.6 V and 8 MHz operating frequency.
The USCI module on the MSP430F2274IYFFT can be used for UART, SPI, or I2C communication. To use the USCI module, configure the module using the USCI control registers, select the desired communication mode, and use the corresponding API functions provided in the MSP430F2274IYFFT driver library.
The flash memory endurance of the MSP430F2274IYFFT is specified as a minimum of 10,000 write/erase cycles at a temperature range of -40°C to 85°C.
