Product details

The TM4C123FH6PMT is a 32-bit ARM Cortex-M4F microcontroller from Texas Instruments' Tiva C series, running at 80 MHz with a hardware floating-point unit. That FPU matters for motor-control and sensor-fusion algorithms that would otherwise eat core cycles in software emulation. The 256 KB Flash and 32 KB RAM (32K x 8) leave room for a modest application image plus a bootloader slot — enough for a field-updatable motor drive or a CAN-to-USB gateway without external memory. The 43 GPIOs, paired with the 12-channel 12-bit ADC, handle a mix of encoder feedback, analog sensor inputs, and parallel control lines in a single-chip architecture.

The base product number is TM4C123.

Frequently asked questions

What is the TM4C123FH6PMT's core speed?

The TM4C123FH6PMT runs at 80 MHz on a 32-bit ARM Cortex-M4F core with a hardware floating-point unit. That clock rate supports real-time control loops and sensor-fusion processing typical in motor drives and industrial gateways.

What is the closest pin-compatible alternative to the TM4C123FH6PMT?

The TM4C123 base product number shares pin compatibility across the Tiva C value-line density options, so a TM4C123GH6PM or TM4C123BE6PM variant with different Flash/RAM sizes can drop into the same 64-LQFP footprint without a PCB layout change. Confirm the specific memory and peripheral set against your firmware image size before swapping.
