The TM4C123FH6PMI runs an ARM Cortex-M4F core at 80 MHz, which includes a single-precision hardware FPU. That FPU unloads the CPU on PID calculations, sensor fusion, and filter math — a real advantage over M3 or M0 parts in motor-drive and instrumentation loops where you need deterministic cycle counts on floating-point operations. Connectivity includes CAN, USB OTG, I²C, SPI, SSI, UART, and QEI. The 12-channel 12-bit ADC is available.
The 64-LQFP (10x10 mm) footprint is a common layout. Supply range is 1.08 V to 3.63 V on Vcc. The internal oscillator is available.
The TM4C123FH6PMI is marked end-of-life (hot) — no official successor part is listed in the record. That means last-time-buy windows have closed at the factory, and new supply moves through surplus and independent channels. We source this MCU to order against an RFQ.
