TM4C123GH6PGEI Key Features

• ARM Cortex-M4F core with hardware FPU for faster floating-point math and better DSP performance in control loops. This reduces execution time for math-intensive tasks.
• 256 KB flash and 32 KB SRAM provide more room for application code and data than many 8- and 16-bit MCUs, simplifying firmware partitioning and OTA strategies.
• USB 2.0 full-speed with device/host/OTG support enables direct peripheral and PC connectivity without external PHYs in many designs.
• Multiple analog inputs and timers support precise ADC sampling, PWM generation and real-time scheduling for motor drives, power supplies and sensor interfaces.

Typical Applications

• Industrial motor control and closed-loop drives where an FPU and fast core speed improve PID loop resolution and update rates for higher torque stability and efficiency.
• Human-machine interfaces with touch buttons, displays and USB connectivity where controller memory and USB support reduce external glue logic and firmware complexity.
• Sensor aggregation and IoT edge nodes requiring multiple ADC channels, timers and GPIO to combine analog sensors, digital inputs and local processing for pre-filtering data.
• Embedded measurement instruments that need deterministic timing, precise ADC sampling and USB device connectivity for data transfer to host systems or test equipment.

TM4C123GH6PGEI Advantages vs Typical Alternatives

The part combines a math-optimized Cortex-M4F core and a larger memory footprint than many 8/16-bit and entry-level 32-bit MCUs. This yields faster signal processing and simpler code architecture for real-time control. The integrated USB 2.0 full-speed interface and multiple analog/timer peripherals reduce external components and board area. Use it when you need a cost-competitive MCU that emphasizes deterministic performance, connectivity and on-chip integration for industrial applications.

FAQ

What development tools support it?

Common toolchains include TI’s Code Composer Studio, Keil MDK and GCC-based toolchains. Development kits, boards and software libraries exist to speed evaluation and firmware development.

Is USB supported on-chip?

Yes. The device implements USB 2.0 full-speed with device, host and OTG capability. This lets designers connect to PCs or USB peripherals without adding external USB controller ICs in many use cases.

Can it handle floating-point math?

Yes. The Cortex-M4F core includes a hardware floating-point unit. This reduces cycle counts for math-heavy algorithms compared with MCUs that rely solely on software floating-point routines.

What temperature range is available?

The device targets industrial operation and is specified for extended ambient temperatures suitable for factory, field and outdoor applications requiring robust temperature tolerance.

How much memory does it provide?

The MCU provides substantial on-chip memory with 256 KB of nonvolatile program flash and 32 KB of SRAM. This supports larger firmware images, buffers and runtime stacks without immediate need for external memory.
