The 12-channel 10-bit ADC covers analog inputs.
The integrated brown-out detect and POR keep the system safe during power-up and sag events. PWM and WDT are on-chip, reducing external glue logic.
Yes, the connectivity set includes UART/USART, along with I²C, SPI, IrDA, and LINbus — all on-chip.
The MSP430F2274MRHATEP is the extended-temperature (-55°C to 125°C) variant of the base MSP430F2274. The core, memory, and peripheral set are identical; the difference is the wider temperature grade and the 'T' suffix in the order code. It is a drop-in replacement for the standard-temperature part where the environment demands it.
