That FPU is the differentiator versus a plain M4 or M3 part — it handles PID coefficients, sensor fusion vectors, and filter math without software emulation, so the loop closure stays deterministic. On the peripheral side it carries CAN, I²C, SPI, SSI, UART, and IrDA — enough for a CANopen node with a local sensor bus and a debug UART. The 12-bit ADC with 12 channels covers analog feedback from current shunts or thermistors without an external converter. ## Industrial temperature range — deployment context The TM4C1231H6PMI7R carries an EOL hot lifecycle stage. The manufacturer's last-time-buy window has closed or is closing. Sourcing is through independent distribution against an RFQ.","metaTitle":"TM4C1231H6PMI7R Tiva C ARM Cortex-M4F MCU, 80 MHz, 256 KB Flash","metaDescription":"TM4C1231H6PMI7R from Texas Instruments Tiva C series. 32-bit ARM Cortex-M4F at 80 MHz with 256 KB Flash, 32 KB RAM, CAN/I²C/SPI/UART.
