Product details
Overview
TM4C123GH6PGEI7 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, 12-bit ADC (1 MSPS, 12 channels), and 48 GPIOs in a 144-pin LQFP package. It serves as a main system controller in industrial HMI, motor control, and USB-connected embedded devices.
For engineers reviewing the TM4C123GH6PGEI7 datasheet, TM4C123GH6PGEI7 pinout, TM4C123GH6PGEI7 application, or TM4C123GH6PGEI7 equivalent, key selection considerations include its integrated USB PHY, hibernation module with RTC and battery-backed memory, dual CAN 2.0B controllers, and support for deterministic real-time control via hardware PWM and quadrature encoder interfaces.
Technical Context
The TM4C123GH6PGEI7 integrates a single-core ARM Cortex-M4F CPU with hardware floating-point unit (FPU), memory protection unit (MPU), and nested vectored interrupt controller (NVIC). It supports Thumb-2 instruction set, 24-bit SysTick timer, and vector table relocation for flexible bootloader and RTOS deployment.
Its system-level integration includes a programmable clock tree with PLL, multiple low-power modes (sleep, deep-sleep, hibernate), and on-chip voltage regulators enabling direct 3.3 V operation from 5 V or battery sources. The hibernation module provides RTC, battery-backed RAM (2 KB), and wake-on-external-event capability independent of main power rail.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | ARM Cortex-M4F @ 80 MHz with FPU and MPU - enables real-time signal processing and deterministic control loops. |
| Memory | 256 KB flash + 32 KB SRAM + 2 KB hibernate RAM - sufficient for standalone firmware with USB stack and sensor fusion algorithms. |
| ADC | 12-bit, 1 MSPS, 12-channel - supports simultaneous sampling of motor phase currents or multi-sensor analog inputs. |
| USB Interface | USB 2.0 full-speed device/host/OTG with integrated PHY - eliminates external transceiver and reduces BOM cost and PCB area. |
| Timers | 6 × 32-bit GPTM (12 × 16-bit), 2 × watchdog, hibernation timer - provides precise PWM generation, quadrature decoding, and time-stamped event capture. |
| Communication | 2 × CAN 2.0B, 8 × UART, 4 × SPI, 4 × I²C - meets industrial fieldbus and peripheral interface requirements without external bridging ICs. |

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), no hibernation module | Better raw compute throughput but higher power in sleep; lacks battery-backed RTC and hibernate RAM | Select when higher CPU performance and larger code space outweigh USB integration and ultra-low-power hibernation needs. |
| MSP432P401RIPZT | ARM Cortex-M4F @ 48 MHz, 2 MB flash, 256 KB SRAM, integrated USB PHY, hibernate mode (but no battery-backed RAM) | Lower max frequency, larger memory, same USB integration, but missing hibernation RTC and battery-backed RAM | Select when large firmware footprint and USB device functionality are critical, and sub-µA hibernation with RTC is not required. |
Compared with STM32F407VGT6 and MSP432P401RIPZT, the TM4C123GH6PGEI7 uniquely combines USB PHY integration, hibernation with battery-backed RAM and RTC, and dual CAN - making it optimal for cost-sensitive, battery-aware industrial gateways requiring field-upgradability and long-term data retention.

FAQ
What is the maximum operating frequency of the TM4C123GH6PGEI7?
The TM4C123GH6PGEI7 operates at a maximum system clock frequency of 80 MHz, achieved via its internal PLL that accepts a 4–25 MHz crystal or external clock source. This frequency is sustained across the full industrial temperature range (–40°C to +105°C) and supports deterministic real-time execution of control algorithms and USB transfers without throttling.
Does the TM4C123GH6PGEI7 include an integrated USB physical layer (PHY)?
Yes, the TM4C123GH6PGEI7 integrates a full-speed USB 2.0 PHY compliant with USB specification revision 2.0. It supports device, host, and OTG modes without requiring external transceivers - only standard USB ESD protection diodes are needed on DP/DM lines. This integration reduces bill-of-materials cost and board space versus MCUs requiring external PHY chips.
What low-power modes does the TM4C123GH6PGEI7 support, and what is its lowest hibernate current?
The TM4C123GH6PGEI7 supports Sleep, Deep-Sleep, and Hibernate modes. In Hibernate mode with RTC enabled and battery-backed RAM active, typical current consumption is 1.4 µA at 3.3 V and 25°C. With RTC disabled and only hibernate RAM retained, current drops to 800 nA - verified per TI datasheet SPMS375E section 7.3.7.
How many analog-to-digital converter (ADC) channels does the TM4C123GH6PGEI7 provide, and what is its sampling rate?
The TM4C123GH6PGEI7 features a single 12-bit ADC with up to 12 external input channels and a maximum sampling rate of 1 MSPS (mega-samples per second). It includes four sample sequencers, hardware averaging (up to 64 samples), and digital comparators - enabling high-precision, time-critical measurements such as motor current sensing or multi-sensor monitoring.
Is the TM4C123GH6PGEI7 pin-compatible with other Tiva C-series microcontrollers?
No, the TM4C123GH6PGEI7 is not pin-compatible with other Tiva C-series variants like TM4C1294NCPDT or TM4C1233H6PGE due to differences in pin count (144 vs. 128 or 64), peripheral assignment, and power domain layout. Its 144-pin LQFP footprint is specific to the GH6PGE family; migration requires PCB redesign even within the same product line.
