Expect to fit a small state machine, a few calibration tables, and a UART or SPI driver — not a full RTOS or TCP/IP stack. The integrated slope A/D converter handles slow analog inputs (e.g., temperature or battery monitoring) without an external ADC, but its conversion rate is lower than a SAR type; factor that into the sampling interval.","metaTitle":"MSP430F2121IDGVR 16-bit MCU, 16 MHz, 4 KB Flash, 20-TFSOP","metaDescription":"TI MSP430F2121IDGVR 16-bit MCU, 16 MHz core, 4 KB Flash, 256 x 8 RAM, -40°C to 85°C, 20-TFSOP.
