Product details
Overview
TM4C123GH6ZRBT7 from Texas Instruments is an ARM Cortex-M4F-based microcontroller with 256 KB Flash, 32 KB SRAM, and integrated peripherals including USB 2.0 OTG, 8× PWM outputs, 12-bit 1MSPS ADC (8 channels), and dual CAN 2.0A/B controllers - deployed in industrial motor control, smart sensor nodes, and USB-connected embedded gateways.
For engineers reviewing the TM4C123GH6ZRBT7 datasheet, TM4C123GH6ZRBT7 pinout, TM4C123GH6ZRBT7 application, or TM4C123GH6ZRBT7 equivalent, key selection criteria include its 80 MHz operation, hibernation mode with RTC and battery-backed memory, JTAG/SW-DP debug interface, and QFN-64 package with 51 GPIOs supporting peripheral multiplexing.
Technical Context
The TM4C123GH6ZRBT7 integrates a 32-bit ARM Cortex-M4F core with hardware floating-point unit (FPU), enabling deterministic real-time signal processing for closed-loop motion control. It supports Thumb-2 instruction set, NVIC with 80 interrupt lines, and MPU for memory protection.
System-level integration includes a programmable clock tree with PLL, multiple low-power modes (sleep/ deep-sleep/hibernate), and on-chip ROM with TivaWare™ peripheral driver library. Peripheral interconnect uses AHB/APB buses with configurable priority arbitration for μDMA-controlled transfers across UART, SPI, I²C, ADC, and timers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | ARM Cortex-M4F @ 80 MHz - delivers deterministic DSP operations via single-cycle MAC and FPU for motor control algorithms. |
| Memory | 256 KB Flash + 32 KB SRAM + 2 KB EEPROM - enables firmware updates in-field and nonvolatile parameter storage without external components. |
| ADC | 12-bit, 1 MSPS, 8-channel - supports simultaneous sampling of analog sensors (e.g., current/voltage/temperature) in motor drives. |
| PWM | 8× 16-bit PWM outputs with dead-band generation - directly drives 3-phase inverter bridges with precise timing control. |
| Connectivity | USB 2.0 OTG + 2× CAN 2.0A/B + 4× UART + 4× SPI + 4× I²C - enables multi-protocol fieldbus communication and host interface in industrial gateways. |
| Low-Power Modes | Hibernate mode draws 1.6 µA with RTC active - extends battery life in remote sensor nodes while retaining timekeeping and wake-on-event capability. |
| Debug Interface | JTAG + SW-DP - provides full visibility into register state, memory, and real-time execution for development and validation. |
Pinout & Package
Package: 64-pin QFN (9 mm × 9 mm, 0.5 mm pitch), RoHS-compliant, thermal pad exposed on underside for enhanced power dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VDDA, VDDC | Power supply inputs | Digital (3.3 V), analog (3.3 V), and core (1.2 V) rails - require separate decoupling to ensure ADC accuracy and core stability. |
| GND, GNDA | Ground returns | Digital and analog ground separation minimizes noise coupling into sensitive analog circuits like ADC and internal temperature sensor. |
| PD0–PD7, PE0–PE5, PF0–PF4, etc. | GPIO pins | 51 total GPIOs with configurable pull-up/down, slew rate, and drive strength - support peripheral function multiplexing (e.g., UART0 on PA0/PA1, CAN0 on PB4/PB5). |
| USB0EPEN, USB0VBUS | USB interface control | Enable detection and VBUS sensing for OTG role negotiation - required for host/peripheral auto-switching in USB-connected devices. |
| RTCCLK, HIB, LFXOSC | Hibernation module signals | Support battery-backed RTC operation and wake-from-hibernate using external crystal (32.768 kHz) or internal oscillator. |
Key Features
| Feature | Design Value |
|---|---|
| Floating-Point Unit (FPU) | Hardware-accelerated IEEE 754 single-precision math - eliminates software emulation overhead in PID tuning and FFT-based diagnostics. |
| μDMA Controller | 32-channel controller with scatter-gather support - offloads CPU during high-throughput data movement (e.g., ADC streaming to SRAM or UART transmission). |
| Hibernation Module | Independent power domain with RTC, battery-backed RAM (2 KB), and wake sources (GPIO, RTC match, external interrupt) - enables ultra-low-power operation without external PMIC. |
| Peripheral Integration | On-die USB PHY, CAN transceivers not required, and internal voltage regulators - reduces BOM count and PCB footprint in space-constrained designs. |
| TivaWare™ Support | ROM-resident driver library with API abstraction - accelerates firmware development and ensures consistent peripheral initialization across TM4C family variants. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TM4C1294NCPDT | ARM Cortex-M4F @ 120 MHz, 1 MB Flash, integrated Ethernet MAC + PHY, no hibernate mode | Better suited for networked HMI or gateway applications requiring TCP/IP stack and high-speed connectivity | Select when Ethernet or higher CPU bandwidth is required; avoid if ultra-low-power hibernation is critical. |
| STM32F407VGT6 | ARM Cortex-M4F @ 168 MHz, 1 MB Flash, no integrated USB PHY, requires external crystal for full-speed USB | Stronger floating-point performance but lacks integrated USB PHY and hibernation-optimized power domains | Prefer for compute-intensive tasks where external USB transceiver is acceptable and battery life is secondary. |
Compared with TM4C123GH6ZRBT7, TM4C1294NCPDT offers higher throughput and networking capability at the cost of power efficiency, while STM32F407VGT6 delivers greater raw FPU performance but requires additional components for USB and lacks TI's hibernation architecture.

FAQ
What is the maximum operating frequency of the TM4C123GH6ZRBT7?
The TM4C123GH6ZRBT7 operates at a maximum system clock frequency of 80 MHz, achieved via its on-chip PLL that accepts input from an external 4–25 MHz crystal or internal oscillator. This frequency is fully supported across all peripherals and memory subsystems, and the ARM Cortex-M4F core executes instructions deterministically at this rate for real-time control tasks.
Does the TM4C123GH6ZRBT7 include an integrated USB physical layer?
Yes, the TM4C123GH6ZRBT7 includes a full-speed USB 2.0 On-The-Go (OTG) physical layer integrated into the die. This eliminates the need for an external USB transceiver and supports both device and host roles. The USB module is compliant with USB 2.0 specifications and includes dedicated endpoints, FIFO buffers, and suspend/resume logic managed by the USB controller.
How many analog-to-digital converter (ADC) channels does the TM4C123GH6ZRBT7 support?
The TM4C123GH6ZRBT7 features a 12-bit successive-approximation ADC with up to 8 single-ended input channels or 4 differential pairs. It supports sample rates up to 1 MSPS, hardware averaging across up to 64 samples, and flexible trigger sources including PWM events and timer matches - making it suitable for precision analog acquisition in motor control and sensor interfaces.
What debug interfaces are supported by the TM4C123GH6ZRBT7?
The TM4C123GH6ZRBT7 supports both JTAG and Serial Wire Debug (SWD) protocols via dedicated pins (TCK, TMS, TDI, TDO, nTRST, SWDIO, SWCLK). These interfaces provide full access to core registers, memory, flash programming, and real-time trace capabilities through TI's XDS110 or third-party debug probes compatible with ARM CoreSight standards.
Is the TM4C123GH6ZRBT7 qualified for extended temperature operation?
Yes, the TM4C123GH6ZRBT7 is rated for operation from –40°C to +105°C ambient temperature, meeting industrial-grade requirements. This rating applies to the full range of specified electrical parameters, including Flash endurance, SRAM retention, and peripheral functionality - validated per TI's production test flow and documented in the official datasheet revision SPMS378E.
