The MSP430G2452IRSA16R: On-chip peripherals include an 8-channel 10-bit ADC, a brown-out detect and POR reset, a DMA controller, a PWM timer, and a watchdog timer. The USI module handles I²C and SPI in software-configurable mode — useful for talking to a temperature sensor, an EEPROM, or a small display over a two-wire bus.
Industrial temperature grade and 16-QFN package
The 16-QFN package with exposed pad (4 mm x 4 mm) keeps board area small and provides a low-inductance ground path through the centre pad — important for the internal oscillator stability and ADC noise floor.
The MSP430G2xx family has broad second-source availability through TI's own distribution network, so supply continuity is stable.
