Product details
Overview
TM4C123GH6PGET from Texas Instruments is an ARM Cortex-M4F-based microcontroller with 80 MHz operation, 256 KB flash, 32 KB SRAM, and integrated USB 2.0 OTG, PWM, ADC (12-bit, 1MSPS), and multiple serial interfaces (UART, SPI, I²C). It serves as a main system controller in industrial motor drives, smart sensor nodes, and USB-connected embedded control systems.
For engineers reviewing the TM4C123GH6PGET datasheet, TM4C123GH6PGET pinout, TM4C123GH6PGET application, or TM4C123GH6PGET equivalent, key selection criteria include its 80 MHz FPU-enabled core, 12-bit 1MSPS ADC with hardware averaging, USB OTG support, hibernation module with RTC and battery-backed memory, and QFP-144 package compatibility with TI's TivaWare™ software stack.
Technical Context
The TM4C123GH6PGET integrates a single-core ARM Cortex-M4F processor with floating-point unit and 200 µA/MHz active power efficiency. It features a 32-bit bus architecture, memory protection unit (MPU), and nested vectored interrupt controller (NVIC) supporting up to 80 interrupts.
System-level integration includes a hibernation module with real-time clock, battery-backed RAM, and wake-on-RTC/external-pin capability; a μDMA controller with 32 channels; and analog subsystem with four 12-bit ADC sample sequencers, internal temperature sensor, and digital comparators.
Key Specifications

Pinout & Package
TM4C123GH6PGET uses a 144-pin LQFP (PGE) package with exposed thermal pad. Pin functions are defined across five GPIO ports (A–E), plus dedicated peripheral pins for USB, crystal oscillator, JTAG/SW-DP debug, and power domains (VDD, VDDA, VDDC, VDDIO, VSS).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VDDA, VDDC, VDDIO | Power supply inputs | Differentiated rail domains enable noise isolation: VDDA powers analog circuitry (ADC, comparator), VDDC supplies core logic, VDDIO sets I/O voltage level (1.8–3.3 V configurable). |
| USB0VBUS, USB0ID, USB0DM, USB0DP | USB 2.0 OTG interface | Full-speed USB device/host capability with integrated transceiver; USB0VBUS detects host connection; USB0ID selects device/host role. |
| PD0–PD7, PE0–PE5, PF0–PF4 | GPIO with alternate functions | Multi-function pins supporting UART, I²C, SPI, PWM, ADC input, and NMI - e.g., PF0 can serve as NMI or analog input channel 18. |
| JTAG/SWD Pins (TCK, TMS, TDI, TDO, SWDIO, SWCLK) | Debug interface | Supports both legacy JTAG and ARM Serial Wire Debug (SWD); SWD reduces pin count to two signals while retaining full debug visibility and flash programming. |
| OSC0, OSC1 | Clock input | Accepts 4–25 MHz crystal or external clock source; feeds PLL to generate system clock up to 80 MHz with ±0.5% accuracy over temperature. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32F407VGT6 | ARM Cortex-M4F @ 168 MHz, 1 MB flash, no integrated USB PHY, requires external crystal for full-speed USB | Better raw performance and larger memory, but higher BOM cost and layout complexity due to external USB transceiver requirement | Select when >80 MHz clock speed, >256 KB flash, or Ethernet MAC+PHY integration is required; avoid if USB simplicity and low-cost BOM are priorities. |
| RP2040 | Dual-core ARM Cortex-M0+, 2 MB flash, no analog peripherals (no ADC, no DAC), no USB device stack in ROM | Lower cost and power, but lacks integrated analog sensing, hibernation, and production-grade USB device firmware support | Select for cost-sensitive consumer IoT endpoints where analog sensing and industrial reliability are not required; avoid for motor control or sensor node applications needing ADC or RTC. |
Compared with STM32F407VGT6 and RP2040, the TM4C123GH6PGET provides balanced performance, integrated USB PHY, production-ready TivaWare drivers, and industrial-grade analog features - making it optimal for mid-tier embedded control where BOM simplicity, analog integration, and USB plug-and-play matter more than peak clock speed or ultra-low cost.

FAQ
What is the maximum operating frequency of the TM4C123GH6PGET?
The TM4C123GH6PGET operates at a maximum system clock frequency of 80 MHz, achieved via its integrated PLL that multiplies an external 4–25 MHz crystal or clock source. This frequency is sustained across the full industrial temperature range (–40°C to +105°C) and is supported by the ARM Cortex-M4F core's pipeline and memory subsystem, enabling deterministic real-time execution of control loops and communication stacks in the TM4C123GH6PGET.
Does the TM4C123GH6PGET include an integrated USB physical layer (PHY)?
Yes, the TM4C123GH6PGET integrates a full-speed USB 2.0 OTG physical layer (PHY) compliant with USB specification revision 2.0. This eliminates the need for external transceivers and allows direct connection to USB hosts or devices using only passive termination resistors. The TM4C123GH6PGET supports both device and host modes, and its USB controller includes dedicated DMA channels and endpoint buffers managed by TI's TivaWare™ USB stack.
How much analog-to-digital converter (ADC) capability does the TM4C123GH6PGET provide?
The TM4C123GH6PGET features a 12-bit successive-approximation ADC with up to 1 million samples per second (1 MSPS), four independent sample sequencers, and hardware averaging across up to 64 samples. It supports 14 analog input channels, includes an internal temperature sensor, and provides digital comparators for threshold-triggered events - all accessible without external signal conditioning in the TM4C123GH6PGET.
What debug interfaces are supported by the TM4C123GH6PGET?
The TM4C123GH6PGET supports both JTAG and ARM Serial Wire Debug (SWD) protocols via dedicated pins (TCK, TMS, TDI, TDO, SWDIO, SWCLK). SWD mode uses only two pins and is preferred for production programming and debugging due to reduced pin count and full feature parity with JTAG. TI's Code Composer Studio and third-party tools like OpenOCD fully support both interfaces for the TM4C123GH6PGET.
Is the TM4C123GH6PGET suitable for low-power battery-operated applications?
Yes, the TM4C123GH6PGET includes a dedicated hibernation module that achieves 1.7 µA deep-sleep current while maintaining RTC operation and 2 KB of battery-backed SRAM. Wake-up sources include RTC alarms, external GPIO pins, and brown-out detection. This makes the TM4C123GH6PGET well-suited for long-life battery-powered sensor nodes and portable instrumentation where runtime between replacements must exceed one year.
