The CAN 2.0 interface (one node) is the standout for industrial bus nodes — motor drives, valve banks, or remote I/O blocks. I²C, SPI, SSI, and UART/USART cover local sensor links and debug consoles. 43 I/O in a 64-LQFP means most pins are usable; watch the analog function muxing on the 12-channel 12-bit ADC — those pins double as GPIO, so a full ADC scan uses 12 of the 43 I/O. Supply range is 1.08 V to 3.63 V.","metaTitle":"TI TM4C1231C3PMIR Tiva C ARM Cortex-M4F MCU, 80 MHz","metaDescription":"Texas Instruments TM4C1231C3PMIR 32-bit ARM Cortex-M4F MCU, 80 MHz, 32 KB Flash, 12 KB RAM, 2 KB EEPROM, CAN/I2C/SPI/UART, 64-LQFP, -40°C to 85°C.
