Product details
Overview
TM4C123GH6ZRBI7 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 -40°C to +85°C industrial temperature range in a 100-pin LQFP package. It serves as the main control unit in motor drive firmware, smart sensor nodes, and USB-connected embedded gateways.
For engineers reviewing the TM4C123GH6ZRBI7 datasheet, TM4C123GH6ZRBI7 pinout, TM4C123GH6ZRBI7 application, or TM4C123GH6ZRBI7 equivalent, key selection considerations include its integrated USB PHY, hibernation module with RTC and battery-backed memory, deterministic real-time interrupt latency (<12 cycles), and TivaWare™ software support for rapid peripheral configuration.
Technical Context
The TM4C123GH6ZRBI7 implements a full-featured ARM Cortex-M4F core with hardware floating-point unit (FPU), single-cycle MAC, and bit-band addressing. Its system-level integration includes a 12-channel μDMA controller, configurable GPIOs with slew-rate control, and a hibernation module supporting VBAT backup and wake-on-RTC match.
Peripherals are clock-gated and power-managed via the system control block (SCB) and run-mode clock gating (RCC). All analog and digital peripherals-including dual 12-bit ADCs with sequencer-based sampling, four 32-bit general-purpose timers with PWM and capture capability, and three UARTs with IrDA/ISO7816 support-are directly memory-mapped and accessible via APB/AHB buses without external glue logic.

Pinout & Package
TM4C123GH6ZRBI7 is housed in a 100-pin LQFP package with exposed thermal pad (EP). Pin functions are defined by GPIO port mapping and peripheral multiplexing controlled via the GPIO AFSEL register. Power pins include VDD, VDDA, VDDC, VDDIO, and dedicated ground planes for analog/digital domains.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VDDA, VDDC, VDDIO | Power supply inputs | Separate rails for core (VDDC), analog (VDDA), I/O (VDDIO), and system (VDD); require individual decoupling |
| GND, GNDA, GNDD | Ground terminals | Dedicated analog ground (GNDA), digital ground (GNDD), and system ground (GND) for noise isolation |
| USB0VBUS, USB0ID, USB0P, USB0N | USB 2.0 OTG interface | Integrated PHY requires no external transceiver; USB0ID enables OTG role detection |
| PD0–PD7, PE0–PE5, PF0–PF4 | GPIO ports with alternate functions | Configurable as UART, I²C, SPI, PWM, or ADC inputs; PF0–PF4 support NMI, user switches, and LEDs |
| OSC0, OSC1 | Crystal oscillator inputs | Supports 4–25 MHz crystal or external clock; internal PLL generates 400 MHz VCO for 80 MHz system clock |
| HIB, VBAT, RTCCLK | Hibernation module interface | Enables battery-backed RTC operation and wake-on-alarm; VBAT maintains hibernation RAM during main power loss |

FAQ
What is the maximum operating frequency of the TM4C123GH6ZRBI7?
The TM4C123GH6ZRBI7 runs at a maximum system clock frequency of 80 MHz, derived from an internal PLL that accepts 4–25 MHz crystal or external clock input. This frequency is fully supported across the entire industrial temperature range (-40°C to +85°C) and is verified in production testing per TI's standard warranty. The TM4C123GH6ZRBI7 achieves deterministic real-time performance with sub-12-cycle interrupt latency at this clock rate.
Does the TM4C123GH6ZRBI7 include an integrated USB physical layer (PHY)?
Yes, the TM4C123GH6ZRBI7 integrates a full-speed USB 2.0 OTG PHY compliant with USB specification revision 2.0. It supports device, host, and OTG modes without external transceivers. The PHY includes internal termination resistors, VBUS sensing (USB0VBUS), ID pin detection (USB0ID), and a 1.2 kB FIFO-enabling direct connection to USB connectors with only passive ESD protection required.
What analog peripherals are included in the TM4C123GH6ZRBI7?
The TM4C123GH6ZRBI7 includes two independent 12-bit analog-to-digital converters (ADCs), each supporting up to 16 input channels, 1 MSPS sampling rate, hardware sample averaging (2–64 samples), and programmable trigger sources (PWM, timer, software). It also features an internal temperature sensor and digital comparators for threshold-based event generation-all accessible without external components.
Is the TM4C123GH6ZRBI7 qualified for automotive applications?
No, the TM4C123GH6ZRBI7 is rated for industrial temperature range (-40°C to +85°C) and is not AEC-Q100 qualified. While it shares architectural features with TI's automotive-grade C2000™ and Hercules™ families, the TM4C123GH6ZRBI7 lacks automotive-specific qualification, extended temperature screening, and fault-tolerant design elements required for automotive safety-critical systems.
How does the hibernation module function in the TM4C123GH6ZRBI7?
The hibernation module in the TM4C123GH6ZRBI7 retains 256 bytes of RAM and the real-time clock (RTC) while main power is removed, using a separate VBAT supply (1.65–3.6 V). It supports wake-up via RTC alarm, external GPIO pin, or HIB interrupt. During hibernation, current consumption drops to ~1.1 µA typical, enabling battery-powered operation for months in sensor monitoring or alarm-panel standby applications.
