Product details
Overview
TM4C123GH6PGET7R 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 multiple UART/SPI/I²C interfaces. It operates at 80 MHz, supports -40°C to +105°C industrial temperature range, and is used in motor control, industrial automation, and embedded HMI systems.
For engineers reviewing the TM4C123GH6PGET7R datasheet, TM4C123GH6PGET7R pinout, TM4C123GH6PGET7R application, or TM4C123GH6PGET7R equivalent, key selection criteria include its integrated USB PHY, dual CAN 2.0B controllers, hibernation module with RTC and battery-backed memory, and support for TivaWare™ software stack and TI's Code Composer Studio™ IDE.
Technical Context
The TM4C123GH6PGET7R implements a full-featured ARM Cortex-M4F core with single-precision floating-point unit (FPU), NVIC with 80 interrupt lines, and SysTick timer. Its system-level integration includes a clock tree with PLL, multiple power domains (run/hibernate/sleep), and configurable GPIOs with slew-rate control and programmable pull-up/down.
Peripherals are tightly coupled via the μDMA controller supporting 32-channel arbitration and peripheral-to-memory transfers without CPU intervention. Analog subsystem includes four independent 12-bit ADC sample sequencers with hardware averaging, internal temperature sensor, and digital comparators - all synchronized to PWM timers for precise motor phase current sampling.

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 or CAN transceivers - requires external PHY and CAN transceiver. | Lacks hibernation module and battery-backed RAM; higher clock speed but larger code footprint for equivalent motor control tasks. | Preferred when higher CPU throughput is needed and external interface components are acceptable in BOM. |
| MSP432P401RIPZ | ARM Cortex-M4F @ 48 MHz, 2 MB flash, integrated AES accelerator, lower power hibernate mode (< 100 nA), no CAN or USB device stack support. | No native CAN or USB device capability; optimized for ultra-low-power sensor hubs rather than industrial control. | Selected for battery-powered wireless sensor nodes where cryptographic security and sub-µA sleep dominate over fieldbus connectivity. |
Compared with STM32F407VGT6 and MSP432P401RIPZ, the TM4C123GH6PGET7R delivers balanced performance, integrated USB/CAN PHYs, and industrial-grade hibernation - making it optimal for cost-sensitive, fieldbus-connected embedded controllers requiring minimal external components.

FAQ
What is the maximum operating frequency of the TM4C123GH6PGET7R?
The TM4C123GH6PGET7R operates at a maximum system clock frequency of 80 MHz, achieved via its on-chip PLL that accepts input from an external crystal (4–25 MHz) or internal oscillator. This frequency is fully supported across the full industrial temperature range (-40°C to +105°C), and all peripherals-including USB, CAN, and ADC-are specified to function reliably at this rate. The TM4C123GH6PGET7R does not support overclocking beyond 80 MHz per TI's production data specifications.
Does the TM4C123GH6PGET7R include an integrated USB physical layer?
Yes, the TM4C123GH6PGET7R integrates a full-speed USB 2.0 physical layer (PHY) supporting device, host, and OTG modes. This eliminates the need for an external USB transceiver in most designs. The USB interface uses dedicated pins (USB0DP/USB0DM) and supports up to 12 Mbps with on-chip termination and biasing. The TM4C123GH6PGET7R also includes a USB controller with endpoint buffers and DMA support managed by the μDMA engine.
How many CAN interfaces does the TM4C123GH6PGET7R support?
The TM4C123GH6PGET7R integrates two independent CAN 2.0B controllers (CAN0 and CAN1), each with dedicated message objects, transmit/receive FIFOs, and bit-rate configuration registers. These controllers support standard and extended identifiers, loopback mode for self-test, and automatic retransmission. Note that external CAN transceivers are required for bus connection - the TM4C123GH6PGET7R provides only the protocol controller and does not include physical-layer drivers.
What is the purpose of the hibernation module in the TM4C123GH6PGET7R?
The hibernation module in the TM4C123GH6PGET7R enables ultra-low-power operation with retention of critical state: it maintains a real-time clock (RTC), 2 KB of battery-backed RAM, and wake-up capability via external pins or RTC alarms while drawing less than 1.4 µA from VBAT. This allows the TM4C123GH6PGET7R to serve as a persistent timekeeper and event logger in battery-powered applications such as smart sensors and energy monitors without requiring external backup circuitry.
Is the TM4C123GH6PGET7R pin-compatible with other Tiva C Series microcontrollers?
No, the TM4C123GH6PGET7R is not universally pin-compatible across the Tiva C Series. While it shares the 144-pin LQFP package with some variants (e.g., TM4C123GH6PM), pin functions differ significantly due to variations in peripheral sets - for example, TM4C123GH6PM lacks USB PHY pins and has different ADC channel mappings. Direct replacement requires verification of signal mapping, power domain routing, and thermal pad layout against the specific target variant's datasheet.
