Product details
Overview
TM4C123GH6ZRBI from Texas Instruments is an ARM Cortex-M4F-based microcontroller with 256 KB Flash, 32 KB SRAM, and integrated USB 2.0 OTG, PWM, ADC (12-bit, 1MSPS), and multiple serial interfaces (UART, SPI, I²C). It operates at 80 MHz and supports hibernation mode for ultra-low-power operation in battery-powered edge nodes.
For engineers reviewing the TM4C123GH6ZRBI datasheet, TM4C123GH6ZRBI pinout, TM4C123GH6ZRBI application, or TM4C123GH6ZRBI equivalent, key selection criteria include its integrated USB PHY, 12-channel PWM with dead-band control, 12-bit 1-MSPS ADC with hardware averaging, hibernation module with RTC and battery-backed memory, and support for TivaWare™ software stack.
Technical Context
The TM4C123GH6ZRBI integrates a 32-bit ARM Cortex-M4F core with single-precision floating-point unit and NVIC supporting up to 80 interrupts. Its system-level integration includes a hibernation module with VBAT-supplied RTC, 2 KB battery-backed RAM, and wake-on-external-pin capability.
Peripherals include four 32-bit general-purpose timers (with PWM/CCP), two watchdog timers, eight UARTs (one with ISO 7816 and SIR), four I²C modules, four SPI modules, and a 12-bit ADC with four sample sequencers, configurable trigger sources, and digital comparators.

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 crystal for full-speed USB | Lacks hibernation module with RTC and battery-backed RAM; higher performance but larger footprint and higher active power | Choose when higher clock speed, larger Flash, or Ethernet MAC are required-and USB PHY can be added externally. |
| MSP432P401RIPZT | ARM Cortex-M4F @ 48 MHz, 2 MB Flash, 256 KB RAM, integrated USB PHY, ultra-low-power architecture (LPM3: 850 nA) | Lower max frequency and fewer PWM channels; superior deep-sleep efficiency but less motor control peripheral integration | Choose for ultra-low-power sensor endpoints where 48 MHz CPU and minimal active power outweigh PWM/ADC channel count needs. |
Compared with STM32F407VGT6 and MSP432P401RIPZT, the TM4C123GH6ZRBI delivers balanced performance, integrated USB PHY, hibernation-optimized power management, and rich motor-control peripherals in a compact 100-pin LQFP-making it optimal for cost-sensitive, battery-aware embedded systems requiring USB connectivity and deterministic real-time control.

FAQ
What is the maximum operating frequency of the TM4C123GH6ZRBI?
The TM4C123GH6ZRBI operates at a maximum system clock frequency of 80 MHz, derived from its internal precision oscillator (PIOSC), external crystal (4–25 MHz), or PLL-based clock source. This frequency is fully supported across all peripherals-including USB, ADC, and PWM-without derating, and is validated per TI SPMS378E production data (Rev E, June 2014).
Does the TM4C123GH6ZRBI include an integrated USB physical layer (PHY)?
Yes, the TM4C123GH6ZRBI integrates a full-speed USB 2.0 OTG PHY with differential D+ and D– pins, eliminating the need for an external transceiver. It supports device, host, and OTG modes, and includes 1 KB of dedicated endpoint RAM-enabling direct connection to USB cables without additional components.
What low-power modes does the TM4C123GH6ZRBI support, and what is the lowest achievable current draw?
The TM4C123GH6ZRBI supports multiple low-power modes, with hibernate mode achieving ≤1.6 µA typical current draw when powered from VBAT with RTC enabled and hibernation RAM retained. This mode preserves RTC time, 2 KB of battery-backed RAM, and allows wake-up via GPIO, RTC match, or external interrupt-verified in TI's production characterization data.
How many ADC channels and sample sequencers does the TM4C123GH6ZRBI provide?
The TM4C123GH6ZRBI features a 12-bit successive approximation register (SAR) ADC with 12 analog input channels and four independent sample sequencers. Each sequencer supports up to eight steps, configurable trigger sources (timer, processor, external), and hardware averaging (up to 64 samples), enabling flexible, deterministic analog acquisition without CPU intervention.
Is the TM4C123GH6ZRBI pin-compatible with other Tiva C Series microcontrollers?
No, the TM4C123GH6ZRBI is not pin-compatible with other Tiva C Series variants such as TM4C1294NCPDT or TM4C1233H6PZ. Its 100-pin LQFP package has unique pin assignments for USB, hibernation, and peripheral multiplexing. Migration requires PCB redesign-even within the same family-due to differences in power domains, debug interface routing, and peripheral pin mapping.
