Product details
Overview
TM4C123GE6PMI7 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, 12-bit ADC (1 MSPS), and 48 GPIOs in a 64-pin LQFP package. It serves as a main system controller in industrial HMI, motor control edge nodes, and USB-connected sensor gateways.
For engineers reviewing the TM4C123GE6PMI7 datasheet, TM4C123GE6PMI7 pinout, TM4C123GE6PMI7 application, or TM4C123GE6PMI7 equivalent, key selection criteria include USB OTG capability, hibernation mode current (1.7 µA), FPU-enabled real-time math, and TI's TivaWare™ software support for rapid firmware development.
Technical Context
The TM4C123GE6PMI7 integrates a single-core ARM Cortex-M4F with hardware floating-point unit and memory protection unit (MPU), enabling deterministic real-time control with IEEE 754-compliant math operations. Its clock system supports multiple sources including internal RC, external crystal (up to 25 MHz), and PLL-locked operation at 80 MHz.
Peripheral integration includes two UARTs with ISO 7816 and SIR support, two I²C modules with bus timeout detection, four SPI interfaces, and a dedicated μDMA controller with 32-channel arbitration-enabling concurrent high-bandwidth transfers without CPU intervention.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | ARM Cortex-M4F @ 80 MHz - delivers deterministic interrupt latency and hardware-accelerated DSP/floating-point math for motor control loops. |
| Flash / SRAM | 256 KB flash / 32 KB SRAM - sufficient for bootloader + RTOS + application logic with over-the-air update partitioning. |
| ADC | 12-bit, 1 MSPS, 12-channel - supports simultaneous sampling of voltage/current feedback in BLDC motor drives. |
| USB Interface | USB 2.0 OTG (host/device) - enables direct connection to PC host or USB peripherals like HID devices or flash storage. |
| Hibernate Current | 1.7 µA (RTC active) - extends battery life in remote sensor nodes requiring periodic wake-up and data transmission. |
| GPIO Count | 48 configurable GPIOs with 5-V tolerant inputs - simplifies interface to legacy industrial sensors and discrete I/O without level-shifting. |
| Package | 64-pin LQFP (10 × 10 mm, 0.5 mm pitch) - compatible with standard reflow processes and manual prototyping with breakout boards. |
Pinout & Package
TM4C123GE6PMI7 uses a 64-pin LQFP package with exposed thermal pad (EP). Pin functions are defined per TI SPMS373E datasheet Rev E, supporting multiplexed peripheral assignment via GPIO AFSEL registers.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD / VDDA / VDDC | Power supply rails | VDD (3.3 V digital), VDDA (3.3 V analog), VDDC (1.2 V core) - require separate decoupling; VDDA must be clean for ADC accuracy. |
| PD0–PD7, PE0–PE5, PF0–PF4, etc. | General-purpose I/O | 48 total GPIOs with programmable pull-up/down, slew rate, and drive strength - support push-pull, open-drain, and alternate function modes. |
| USB0VBUS, USB0ID, USB0DM, USB0DP | USB 2.0 OTG interface | Dedicated differential pair (DM/DP) with internal transceivers - eliminates need for external PHY; ID pin enables OTG role negotiation. |
| SSI0CLK–SSI0FSS, I2C0SCL–I2C0SDA | Serial peripheral interfaces | Four independent SSI (SPI) modules and two I²C buses - enable concurrent communication with displays, EEPROMs, and sensors. |
| ADC0, ADC1, …, ADC11 | Analog input channels | 12 single-ended or 6 differential ADC inputs mapped to physical pins - support temperature sensing, battery monitoring, and analog sensor interfacing. |
Key Features
| Feature | Design Value |
|---|---|
| Hibernation module with RTC | Enables ultra-low-power operation (1.7 µA) with calendar-based wake-up - ideal for battery-powered environmental monitors. |
| μDMA controller (32 channels) | Offloads CPU from data movement across UART, ADC, and SSI - preserves 80 MHz CPU bandwidth for control algorithms. |
| Integrated USB 2.0 OTG PHY | Eliminates external transceiver; supports device mode (CDC, HID) and host mode (MSC, HID) - reduces BOM cost and PCB area. |
| FPU + MPU | Hardware floating-point unit accelerates trigonometric and filter computations; MPU enforces memory access boundaries for robust firmware partitioning. |
| TivaWare™ software suite | TI-provided driver library, USB stack, and FreeRTOS port - cuts firmware development time by >40% versus bare-metal bring-up. |

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) | Better raw compute throughput but higher BOM cost and layout complexity for USB | Select when >100 MHz CPU performance or larger code footprint is required; verify USB signal integrity with external PHY. |
| MSP432P401RIPZT | ARM Cortex-M4F @ 48 MHz, 2 MB flash, lower power (850 nA hibernate), no USB OTG | Superior low-power metrics but lacks USB connectivity and real-time USB host capability | Select for battery-critical applications without USB requirements; avoid if CDC/HID device or host functionality is needed. |

FAQ
What is the maximum operating frequency of the TM4C123GE6PMI7?
The TM4C123GE6PMI7 operates at a maximum CPU frequency of 80 MHz, achieved via its on-chip PLL locked to an external crystal (up to 25 MHz) or internal oscillator. This frequency is fully supported across the full industrial temperature range (–40°C to +85°C) and enables sub-microsecond interrupt response for time-critical control tasks.
Does the TM4C123GE6PMI7 include an integrated USB physical layer?
Yes, the TM4C123GE6PMI7 integrates a full-speed USB 2.0 OTG physical layer (PHY) with internal transceivers, eliminating the need for external USB PHY components. This allows direct connection of USB cables to the MCU's DM/DP pins and supports both device and host roles using TI's TivaWare™ USB stack.
What is the hibernation current specification for the TM4C123GE6PMI7?
The TM4C123GE6PMI7 achieves a hibernation current of 1.7 µA while maintaining RTC operation and retaining RAM contents. This value is measured under specified conditions (VDD = 3.3 V, T = 25°C) and enables multi-year battery life in wireless sensor nodes that wake periodically to sample and transmit data.
How many analog-to-digital converter (ADC) channels does the TM4C123GE6PMI7 support?
The TM4C123GE6PMI7 features a 12-bit successive-approximation ADC with up to 12 single-ended or 6 differential input channels. It supports programmable sample rates up to 1 MSPS and includes hardware averaging, digital comparators, and an internal temperature sensor - all accessible without CPU intervention via μDMA triggers.
Is the TM4C123GE6PMI7 pin-compatible with other Tiva C Series MCUs?
No, the TM4C123GE6PMI7 is not pin-compatible with other Tiva C Series variants such as TM4C1294NCPDT or TM4C123BH6PGE. While they share architectural similarities and software compatibility via TivaWare™, differences in peripheral mapping, pin count (64 vs. 128), and package type prevent direct PCB replacement without redesign.
