Product details
Overview
TM4C123GH6PMI7 from Texas Instruments is an ARM Cortex-M4F-based microcontroller with 256 KB flash, 32 KB SRAM, and integrated peripherals including USB 2.0, CAN, 8× PWM, 12-bit ADC (1MSPS), and dual QEI. It operates at 80 MHz and supports -40°C to +85°C industrial temperature range in a 64-pin LQFP package. It serves as a main system controller in motor control, industrial automation, and smart sensor nodes.
For engineers reviewing the TM4C123GH6PMI7 datasheet, TM4C123GH6PMI7 pinout, TM4C123GH6PMI7 application, or TM4C123GH6PMI7 equivalent, key selection criteria include Cortex-M4F FPU support, on-chip USB PHY, CAN 2.0B compliance, hibernation module with RTC and battery-backed memory, and full JTAG/SWD debug capability.
Technical Context
The TM4C123GH6PMI7 integrates a 32-bit ARM Cortex-M4F core with single-precision floating-point unit and 16-stage pipeline, enabling deterministic real-time execution for motion control and digital power conversion. Its system-level integration includes a 400 kHz I²C master/slave, four UARTs (one with ISO 7816 and SIR), two SPI modules, and two I²S interfaces.
On-chip analog subsystem comprises two independent 12-bit ADCs with up to 12 input channels each, hardware averaging, and programmable sample sequencers. The hibernation module provides low-power operation with wake-up from GPIO, RTC alarm, or external interrupt while retaining SRAM and register state using VBAT.

FAQ
What is the maximum operating frequency of the TM4C123GH6PMI7?
The TM4C123GH6PMI7 operates at a maximum system clock frequency of 80 MHz, derived from its internal PLL with support for multiple clock sources including precision internal oscillator, external crystal, or external clock input. This frequency is fully supported across the entire industrial temperature range (-40°C to +85°C) and enables real-time execution of complex control loops and communication stacks in the TM4C123GH6PMI7.
Does the TM4C123GH6PMI7 include an integrated USB physical layer?
Yes, the TM4C123GH6PMI7 includes a full-speed USB 2.0 physical layer (PHY) supporting Device, Host, and OTG modes. This eliminates the need for an external USB transceiver IC and simplifies design for applications requiring plug-and-play connectivity, firmware updates, or peripheral hosting - all enabled directly by the TM4C123GH6PMI7.
What low-power features does the TM4C123GH6PMI7 support?
The TM4C123GH6PMI7 supports multiple low-power modes, including Sleep, Deep-Sleep, and Hibernation. In Hibernation mode, it draws as little as 1.6 µA while retaining RTC operation, battery-backed RAM, and wake-up capability via GPIO or external interrupt. This feature is critical for battery-powered applications and is implemented in hardware within the TM4C123GH6PMI7.
Is CAN bus support available on the TM4C123GH6PMI7?
Yes, the TM4C123GH6PMI7 integrates a CAN 2.0B-compliant controller with dedicated CAN0RX and CAN0TX pins.

What debug interfaces are supported by the TM4C123GH6PMI7?
The TM4C123GH6PMI7 supports both JTAG and ARM Serial Wire Debug (SWD) interfaces via dedicated pins. SWD uses only two signals (SWDIO and SWCLK), reducing debug footprint, while JTAG enables full boundary-scan and trace capabilities. Both are fully supported by TI's Code Composer Studio and third-party tools for development and validation of the TM4C123GH6PMI7.
