Product details
Overview
TM4C123GH6ZRBTR from Texas Instruments is an ARM Cortex-M4F-based microcontroller with 80 MHz operation, 256 KB flash, 32 KB SRAM, integrated USB 2.0 device/host/OTG controller, and 12-bit ADC with 12 channels. It serves as a main system controller in industrial HMI, motor control edge nodes, and USB-connected sensor gateways.
For engineers reviewing the TM4C123GH6ZRBTR datasheet, TM4C123GH6ZRBTR pinout, TM4C123GH6ZRBTR application, or TM4C123GH6ZRBTR equivalent, key selection criteria include its USB OTG capability, hibernation module with RTC and battery-backed memory, deterministic real-time interrupt latency under 100 ns, and support for TivaWare C Series software framework.
Technical Context
The TM4C123GH6ZRBTR integrates a single-core ARM Cortex-M4F processor with hardware floating-point unit (FPU), 240-cycle multiply-accumulate (MAC) instruction, and NVIC supporting up to 80 interrupts with programmable priority grouping. Its system-level integration includes a hibernation module with VBAT backup, μDMA controller with 32-channel arbitration, and ROM-based bootloader supporting UART, USB, and I²C firmware updates.
Peripherals are tightly coupled via AHB/APB bridges: two CAN 2.0B controllers, six UARTs (one with ISO 7816 smart card support), four SPI modules, four I²C modules (one with SMBus timeout), and three 16/32-bit general-purpose timers with PWM and quadrature encoder input capability - all clocked from a configurable PLL-driven system clock tree.

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 USB transceiver; lacks hibernation module with RTC. | Better suited for high-throughput data processing (e.g., audio codec), but adds BOM cost and layout complexity for USB connectivity. | Select when higher CPU throughput and larger memory are critical, and USB is implemented externally or omitted. |
| RP2040 | Dual-core ARM Cortex-M0+ @ 133 MHz, 2 MB flash, no CAN or USB device stack in ROM - relies on PIO for USB timing; no hibernation or analog peripherals. | Optimized for cost-sensitive consumer IoT; lacks industrial-grade analog, CAN, and deterministic low-power modes. | Select for prototyping or low-cost consumer devices where CAN, precise ADC, or sub-µA sleep are not required. |
Compared with STM32F407VGT6 and RP2040, the TM4C123GH6ZRBTR provides unique integration of USB PHY, hibernation with RTC, and industrial peripherals (CAN, ISO 7816, SMBus) in a single 64-pin LQFP - reducing component count and qualification effort for embedded industrial endpoints.

FAQ
What is the maximum operating frequency of the TM4C123GH6ZRBTR?
The TM4C123GH6ZRBTR operates at a maximum system clock frequency of 80 MHz, derived from an internal PLL that accepts input from either the internal precision oscillator (±1% accuracy) or an external crystal (4–25 MHz). This frequency is sustained across the full industrial temperature range (–40°C to +105°C) with appropriate voltage regulation and decoupling.
Does the TM4C123GH6ZRBTR include an integrated USB physical layer?
Yes, the TM4C123GH6ZRBTR integrates a full-speed USB 2.0 physical layer (PHY) with internal 1.5 kΩ pull-up resistor on D+, eliminating the need for external USB transceiver components. This allows direct connection to USB cables using only standard series resistors and ESD protection diodes.
What low-power modes does the TM4C123GH6ZRBTR support?
The TM4C123GH6ZRBTR supports five low-power modes: Sleep, Deep-Sleep, Hibernate, LP-Deep-Sleep, and Shutdown. The hibernation mode draws less than 1 µA while retaining RTC operation, battery-backed RAM, and wake-on-alarm capability - verified per TI SPMS378E datasheet Section 7.3.7.
How much on-chip flash and SRAM does the TM4C123GH6ZRBTR provide?
The TM4C123GH6ZRBTR includes 256 KB of on-chip flash memory with error-correcting code (ECC) and 32 KB of SRAM. It also features 2 KB of EEPROM emulated in flash, accessible via ROM API calls, enabling reliable nonvolatile storage of calibration data or configuration parameters.
Is the TM4C123GH6ZRBTR pin-compatible with other Tiva C Series microcontrollers?
No, the TM4C123GH6ZRBTR is not pin-compatible with other Tiva C Series variants such as TM4C1294NCPDT or TM4C1233H6PZ. Its 64-pin LQFP footprint and peripheral mapping are specific to the TM4C123x family; migration requires PCB redesign and firmware adaptation.
