Product details
Overview
TM4C123GH6PMTR from Texas Instruments is an ARM Cortex-M4F-based microcontroller with 80 MHz operation, 256 KB flash, 32 KB SRAM, integrated USB 2.0 OTG, dual CAN 2.0A/B controllers, and 12-bit ADC with 12 channels - deployed in industrial motor control, smart sensor nodes, and USB-connected embedded gateways.
For engineers reviewing the TM4C123GH6PMTR datasheet, TM4C123GH6PMTR pinout, TM4C123GH6PMTR application, or TM4C123GH6PMTR equivalent, key selection considerations include its 80 MHz FPU-enabled core, on-chip USB PHY, hibernation module with RTC and battery-backed memory, and support for deterministic real-time control via PWM and quadrature encoder interfaces.
Technical Context
The TM4C123GH6PMTR integrates a single-core ARM Cortex-M4F processor with hardware floating-point unit (FPU), supporting Thumb-2 instruction set and vector table relocation. It features a 32-bit bus matrix with separate AHB/APB bridges enabling concurrent peripheral access without CPU stalling.
Its system-level integration includes a hibernation module with dedicated 32.768 kHz RTC oscillator, battery-backed 2 KB SRAM, and VDD3ON power mode for ultra-low-power wake-up. The μDMA controller supports 32-channel arbitration with peripheral-to-memory, memory-to-peripheral, and memory-to-memory transfers.

Pinout & Package
TM4C123GH6PMTR is housed in a 64-pin LQFP package with exposed thermal pad. Pin functions are defined per TI SPMS376E datasheet revision E (June 2014), including dedicated JTAG/SWD debug pins, USB D+/D− differential pair, CANH/CANL transceiver pins, and multiplexed GPIO with configurable slew rate and drive strength.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VDDA, VDDC | Supply rails | VDD (3.3 V digital core), VDDA (3.3 V analog), VDDC (1.2 V internal regulator input) - require independent decoupling for noise-sensitive ADC and PLL stability. |
| USB0DP / USB0DM | USB 2.0 differential pair | Integrated PHY eliminates external transceiver; requires 90 Ω differential impedance routing and 1.5 kΩ pull-up on DP for full-speed enumeration. |
| CAN0RX / CAN0TX | CAN 2.0B controller interface | Direct connection to external CAN transceiver (e.g., SN65HVD230); no level-shifting needed - supports 1 Mbps baud rate with built-in loopback test mode. |
| PD0 / PD1 | UART0 I/O | Default UART0 pins (TX/RX); also serve as JTAG TDO/TDI when SWD is disabled - enables shared debug/communication footprint in space-constrained designs. |
| HIBERNATE_RTCCLK | Hibernation module clock input | Accepts 32.768 kHz crystal or external clock; enables RTC operation and wake-up events while main core is powered down. |
| GPIO Pins (PA–PK) | Multiplexed I/O | Up to 43 GPIOs with configurable pull-up/down, open-drain, and edge-triggered interrupts - supports direct interfacing with buttons, LEDs, sensors, and digital actuators. |
Key Features
| Feature | Design Value |
|---|---|
| Floating-Point Unit (FPU) | Hardware-accelerated IEEE 754 single-precision math - reduces PID loop execution time by >10× vs. integer-only implementations. |
| Hibernation Module | Dedicated low-power domain with RTC, battery-backed SRAM, and wake-on-RTC-match or external pin - enables years of operation on coin-cell batteries. |
| USB 2.0 OTG with PHY | On-die USB transceiver compliant with USB 2.0 full-speed (12 Mbps) - eliminates external PHY, simplifies BOM, and supports device/host/OTG roles. |
| μDMA Controller | 32-channel scatter-gather DMA with peripheral request arbitration - offloads CPU from high-bandwidth data movement (e.g., ADC streaming, UART buffering). |
| Quadrature Encoder Interface (QEI) | Two independent QEI modules accepting A/B/Z index signals - enables direct RPM and direction measurement from rotary encoders without CPU polling. |
| Programmable Clock Gating | Per-peripheral clock enable/disable via System Control registers - reduces dynamic power by disabling unused peripherals at runtime. |

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 transceiver; lacks hibernation module with RTC. | Better suited for high-throughput data processing (e.g., audio codec), but higher power in sleep modes (2.5 µA vs. 1.7 µA). | Select when higher clock speed and larger flash are prioritized over ultra-low-power hibernation and integrated USB. |
| RP2040 | Dual-core ARM Cortex-M0+ @ 133 MHz, 2 MB flash, no CAN, no hardware FPU, USB 1.1 only, no hibernation RTC. | Lower cost and simpler toolchain; ideal for consumer IoT but unsuitable for CAN-based industrial networks or FPU-dependent control loops. | Select for cost-sensitive, non-safety-critical applications where CAN, FPU, or sub-2 µA hibernation are not required. |
Compared with STM32F407VGT6 and RP2040, TM4C123GH6PMTR provides unique integration of USB 2.0 OTG with PHY, dual CAN controllers, and a hibernation module with battery-backed RTC - making it optimal for resource-constrained, mixed-protocol industrial endpoints requiring long battery life and deterministic real-time response.

FAQ
What is the maximum operating frequency of the TM4C123GH6PMTR?
The TM4C123GH6PMTR operates at a maximum system clock frequency of 80 MHz, derived from its internal PLL with support for multiple clock sources including external crystals, internal oscillators, and USB SOF synchronization. This frequency is fully supported across all voltage and temperature ranges specified in the SPMS376E datasheet, and the ARM Cortex-M4F core executes instructions at this rate with zero wait states when accessing on-chip flash with prefetch enabled.
Does the TM4C123GH6PMTR include an integrated USB physical layer (PHY)?
Yes, the TM4C123GH6PMTR integrates a full-speed USB 2.0 PHY compliant with the USB specification, eliminating the need for an external transceiver. Its USB0DP and USB0DM pins connect directly to the USB connector with appropriate termination and ESD protection, and the device supports USB device, host, and OTG modes through the USB controller and TivaWare stack.
What low-power modes does the TM4C123GH6PMTR support, and what is its lowest current consumption?
The TM4C123GH6PMTR supports multiple low-power modes including Sleep, Deep-Sleep, and Hibernation. In Hibernation mode with RTC active and 2 KB hibernate SRAM retained, typical current consumption is 1.7 µA at 3.3 V and 25°C. This mode preserves RTC timekeeping and allows wake-up via external pin, RTC match, or tamper event - verified per TI's power consumption characterization in SPMS376E Section 5.2.4.
How many CAN controllers are integrated into the TM4C123GH6PMTR, and what protocol versions do they support?
The TM4C123GH6PMTR integrates two independent CAN controllers (CAN0 and CAN1), each compliant with the ISO 11898-1 standard and supporting CAN 2.0A (standard frame) and CAN 2.0B (extended frame) protocols. Both controllers operate up to 1 Mbps and include message objects, FIFO buffers, and automatic retransmission - confirmed in Sections 1.3.3 and 15.1 of the SPMS376E datasheet.
Is the TM4C123GH6PMTR pin-compatible with other devices in the TM4C123x family?
Yes, the TM4C123GH6PMTR shares the same 64-pin LQFP package and pinout with other TM4C123x variants such as TM4C123GH6PZ and TM4C123BE6PM, differing only in flash size, SRAM capacity, and peripheral enablement. This allows hardware reuse across product tiers - for example, upgrading from 128 KB to 256 KB flash without PCB redesign - as documented in TI's TM4C123x Family Data Sheet (SPMS376E Appendix A).
