• USB full-speed ?? Built-in USB 2.0 support simplifies connectivity for host or device roles without extra controllers.
• Broad GPIO count ?? Up to 43 digital I/O pins provide more channels for sensors, actuators, and user interfaces than many smaller packages.
• Industrial temperature rating ?? Operation from -40 ??C to +85 ??C improves reliability in harsher environments compared with consumer-grade parts.

Typical Applications

• Industrial motor control and drive systems requiring an MCU with floating-point math for efficient PID loops and faster control loop response.
• Embedded human-machine interface panels that need multiple GPIOs, USB connectivity, and on-chip memory for firmware and graphical assets.
• Data acquisition modules where a 12-bit ADC and multiple analog channels provide finer measurement resolution for sensors and transducers.
• Connected industrial sensors and edge devices that combine local signal processing and USB or serial connectivity for system integration.

TM4C123AH6PMI Advantages vs Typical Alternatives

The TM4C123AH6PMI pairs an ARM Cortex-M4F core with larger on-chip flash and SRAM than many 32-bit entry MCUs, delivering faster math and control performance per dollar. Compared with 8-bit and 16-bit controllers, it provides more memory, native 12-bit ADC precision, and native USB full-speed connectivity. These traits reduce external components and simplify designs, offering both cost and board-area advantages over typical alternatives with less integration.
