Product details

What the 80 MHz Cortex-M4F core buys you on this Tiva C part

The Texas Instruments TM4C1232D5PMI is a Tiva C Series 32-bit ARM Cortex-M4F microcontroller with a single-precision floating-point unit, running at 80 MHz. The 49 available GPIOs and the 12-channel 12-bit ADC give it the I/O count for a sensor-fusion node or a motor-control interface without needing an external mux.

Connectivity and peripherals — what is actually on the silicon

That USB port supports both device and host modes, so the part can talk to a thumb drive or a sensor dongle directly. The CAN interface is the real differentiator here — it puts this MCU into automotive body-control and industrial fieldbus roles where a plain UART won't cut it. The internal oscillator means you can bring up the core without an external crystal, though the clock accuracy (±1% typical) matters if the CAN bus timing budget is tight. The DMA engine offloads peripheral-to-memory transfers, which keeps the CPU free for the control loop.

Package and footprint — what the board sees

It ships in a 64-LQFP package with a 10x10 mm body and 0.5 mm pitch, surface-mount only.

Frequently asked questions

Does TM4C1232D5PMI support USB host mode?

Yes, the USB controller on the TM4C1232D5PMI supports both device and host modes, so it can interface directly with USB peripherals like thumb drives or keyboards without an external host controller.

Is TM4C1232D5PMI a direct replacement for TM4C1231?

The TM4C1232D5PMI and TM4C1231 are both Tiva C Series parts in the same 64-LQFP footprint, but the exact pin compatibility and feature set differences should be verified against the respective datasheets. The base product number TM4C1232 indicates a specific memory and peripheral configuration tier within the family.

What is TM4C1232D5PMI's listed speed?

The TM4C1232D5PMI runs at 80 MHz from its ARM Cortex-M4F core, with a single-precision floating-point unit for efficient math in control and sensor algorithms.

What is the closest pin-compatible alternative to TM4C1232D5PMI?

Within the Tiva C TM4C123x family, higher-density variants in the same 64-LQFP package (10x10 mm) are pin-compatible, offering more Flash or SRAM. Check the TM4C1233 and TM4C1236 base numbers for stepped-up memory options while keeping the same footprint and peripheral set.
