It forces a lean firmware approach — no heavy buffering, no RTOS, no large lookup tables. This part is not for data logging or complex protocol stacks; it is for a single-threaded control task where the code fits in a few hundred bytes and the data lives in registers or Flash constants. ## 16-QFN with exposed pad — layout notes The MSP430G2231IRSA16T comes in a 16-VQFN Exposed Pad package (supplier device package 16-QFN, 4x4 mm). The 10 I/O pins are all that is available, so plan the pin allocation early: the ADC inputs share pins with the digital I/O, and the I²C/SPI peripherals are muxed onto specific pins.","metaTitle":"Texas Instruments MSP430G2231IRSA16T 16-bit MCU, 16 MHz","metaDescription":"Texas Instruments MSP430G2231IRSA16T 16-bit MCU, 16 MHz core, 2 KB Flash, 128 B RAM, 10 I/O, 8-ch 10-bit ADC, I²C/SPI, -40°C to 85°C, 16-QFN.
