Product details

That FPU handles sensor fusion and motor-control math without software emulation overhead — a real advantage over the M3 or M0+ siblings in the same package footprint. The 64 KB Flash and 24 KB RAM fit a mid-complexity control loop or a CAN gateway node with a modest data buffer; the 2 KB EEPROM holds calibration constants and boot parameters without external storage.

Connectivity and I/O for industrial integration

The 49 GPIOs, 12-channel 12-bit ADC, and internal oscillator reduce external component count.

Surface-mount only, so plan for a pick-and-place step on the line.

Frequently asked questions

What is TM4C1232D5PMIR's listed speed?

The core runs at 80 MHz, which is the maximum clock speed for this ARM Cortex-M4F device. That 80 MHz, combined with the FPU, gives enough headroom for a 10 kHz current-control loop with sensor filtering in the same cycle budget.
