The 80 MHz core with FPU handles sensor fusion and PID loops without a separate DSP coprocessor. ## Connectivity and I/O for fieldbus and panel integration On the peripheral side, the TM4C123FH6PMIR includes a CAN 2.0 controller for industrial fieldbus, USB OTG for host/peripheral data logging, and multiple UART, SPI, I²C, and SSI serial ports. The 12-channel 12-bit ADC samples analog signals from current shunts or thermocouple amplifiers. The motion-PWM module drives H-bridges or three-phase motor stages directly. The 49 I/O lines in the 64-LQFP package support encoder inputs and pushbuttons alongside serial buses. Mounting is surface-mount on a 10x10 mm body. The TM4C123FH6PMIR is listed with an EOL hot lifecycle status, meaning the last-time-buy window is open but closing. Texas Instruments has not announced a direct pin-compatible successor for this exact order code.","metaTitle":"TM4C123FH6PMIR Tiva C ARM Cortex-M4F MCU, 80 MHz","metaDescription":"TM4C123FH6PMIR from Texas Instruments: 32-bit ARM Cortex-M4F MCU, 80 MHz, 256 KB Flash, 32 KB RAM, industrial temp -40°C to 85°C, 64-LQFP.
