Product details

80 MHz Cortex-M4F with floating-point unit

The part is built for industrial control, motor-drive feedback loops, and human-machine interfaces where deterministic response and math throughput matter. 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.

Frequently asked questions

What is the difference between TM4C123FH6PM and TM4C123FH6PMIR?

The TM4C123FH6PM (without the 'R' suffix) is the tray-pack variant; the TM4C123FH6PMIR ships in Tape & Reel. All electrical and mechanical specifications are identical between the two order codes.

What is the package of TM4C123FH6PMIR?

The TM4C123FH6PMIR is supplied in a 64-lead LQFP package (10x10 mm body) with a 0.5 mm pitch, surface-mount.

What is TM4C123FH6PMIR's listed speed?

The core runs at 80 MHz, which is the maximum clock frequency for this ARM Cortex-M4F device.
