Product details
Overview
TM4C123GE6PZTR from Texas Instruments is an ARM Cortex-M4F-based microcontroller with 256 KB Flash, 32 KB SRAM, integrated USB 2.0 OTG, 12-bit ADC (1MSPS), and dual PWM modules - deployed in industrial motor control, smart sensor nodes, and USB-connected embedded gateways.
For engineers reviewing the TM4C123GE6PZTR datasheet, TM4C123GE6PZTR pinout, TM4C123GE6PZTR application, or TM4C123GE6PZTR equivalent, key selection criteria include its 80 MHz operation, hibernation module with RTC and battery-backed memory, 16-channel μDMA, and full JTAG/SWD debug support for real-time firmware development.
Technical Context
The TM4C123GE6PZTR integrates a single-core ARM Cortex-M4F processor with hardware floating-point unit (FPU), supporting Thumb-2 and DSP instructions. It features a deterministic interrupt latency via NVIC with 8-level priority grouping and vector table relocation capability.
System-level integration includes a programmable clock tree with PLL, multiple low-power modes (sleep, deep-sleep, hibernate), and peripheral-specific clock gating. The hibernation module provides RTC, battery-backed RAM, and wake-on-external-pin or timer event - enabling sub-5 µA retention current in battery-powered applications.
Key Specifications

|---|---|
| CPU Core | ARM Cortex-M4F @ 80 MHz - enables real-time control with hardware FPU for motor phase calculations or sensor fusion. |
| Memory | 256 KB Flash + 32 KB SRAM + 2 KB EEPROM - supports field-upgradable firmware and nonvolatile configuration storage. |
| ADC | 12-bit, 1 MSPS, 12-channel - sufficient for simultaneous sampling of motor current, voltage, and temperature in closed-loop drives. |
| USB Interface | USB 2.0 OTG with PHY - allows direct host/device role switching without external transceiver for diagnostic or firmware update ports. |
| PWM | Dual 16-bit PWM modules with dead-band generation - supports three-phase inverter control with complementary outputs and fault protection. |

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 for full-speed USB. | Better raw performance and memory headroom; less integrated analog/peripheral set than TM4C123GE6PZTR. | Select when higher CPU throughput or larger code footprint is required, and USB is not mandatory or can be added externally. |
| RA4M1 (R7FA4M1AB3CFM) | ARM Cortex-M4F @ 48 MHz, 256 KB Flash, 32 KB SRAM, no USB OTG - includes TrustZone security extensions and CAN FD. | Stronger security and automotive connectivity focus; lower clock speed and missing hibernation module limit ultra-low-power use cases. | Select for secure industrial IoT endpoints requiring secure boot and CAN FD, where sub-µA hibernation is not needed. |
Compared with STM32F407VGT6 and RA4M1, the TM4C123GE6PZTR offers superior integration for USB-connected embedded control - including on-die PHY, hibernation with RTC, and motor-control-optimized PWM - making it optimal for cost-sensitive, battery-aware, or USB-native applications without external component overhead.

FAQ
What is the maximum operating frequency of the TM4C123GE6PZTR?
The TM4C123GE6PZTR operates at a maximum system clock frequency of 80 MHz, achieved via its internal PLL with support for external crystal (4–25 MHz) or internal oscillator sources. This frequency is sustained across the full industrial temperature range (–40°C to +105°C) and enables deterministic real-time execution of control algorithms and communication stacks without overclocking.
Does the TM4C123GE6PZTR include an integrated USB physical layer (PHY)?
Yes, the TM4C123GE6PZTR includes a fully integrated USB 2.0 full-speed (12 Mbps) PHY with on-chip termination resistors and voltage regulators. This eliminates the need for external USB transceivers in most designs, reducing BOM cost and PCB complexity while maintaining compliance with USB specification timing and electrical requirements.
What low-power modes does the TM4C123GE6PZTR support, and what is the lowest achievable current draw?
The TM4C123GE6PZTR supports Sleep, Deep-Sleep, and Hibernate modes. In Hibernate mode with RTC running and battery-backed RAM enabled, typical current draw is ≤5 µA at 25°C. This mode retains register state and supports wake-up via external pin, RTC alarm, or HIB interrupt - ideal for battery-powered sensor endpoints.
How many ADC channels and what resolution does the TM4C123GE6PZTR provide?
The TM4C123GE6PZTR integrates a 12-bit successive-approximation ADC with up to 12 external input channels and a 1 MSPS sample rate. It includes four independent sample sequencers, hardware averaging (up to 64 samples), and an internal temperature sensor - enabling simultaneous high-accuracy acquisition of motor phase currents, bus voltage, and thermal feedback.
Is the TM4C123GE6PZTR pin-compatible with other devices in the Tiva C Series?
The TM4C123GE6PZTR uses a 100-pin LQFP package shared with several other Tiva C Series MCUs (e.g., TM4C123GH6PGE), but pin compatibility is not guaranteed across all variants due to differences in peripheral mapping and alternate function assignments. Always verify pinout against the specific device's datasheet and use TI's PinMux tool for accurate configuration before layout.
