The integrated single-precision floating-point unit (FPU) means PID loops, sensor fusion, and FFT calculations run in hardware rather than software emulation — a real cycle-count difference versus a Cortex-M3 or M4 without FPU.
Connectivity mix: USB OTG, CAN, and serial interfaces
This part carries USB OTG (host/device negotiation), CAN 2.0, multiple SPI/SSI, I²C, UART/USART, IrDA, and Microwire interfaces. For a design that needs to talk to a CAN bus on one side and a USB host on the other — say an industrial gateway or a vehicle telematics node — this single chip covers both without an external USB-to-CAN bridge. The 105 I/O pins in the 144-LQFP package leave plenty of GPIO for local sensors, buttons, and indicators.
The 22-channel 12-bit ADC can sample analog inputs across that temperature range with the internal oscillator — no external reference needed for moderate accuracy.
For dual-sourcing resilience, the Tiva C family includes several 144-pin parts with the same footprint — the TM4C123GH6PM is a common cross-shop candidate with additional Ethernet MAC+PHY, though the pinout differs in the Ethernet signal group.
