Product details
Overview
TM4C129CNCZADI3R from Texas Instruments is an ARM Cortex-M4F-based microcontroller with 120 MHz CPU, 1 MB Flash, 256 KB SRAM, integrated Ethernet MAC+PHY, USB 2.0 OTG, and hardware crypto accelerators (AES/DES/SHA/MD5), deployed in industrial gateways requiring real-time control, secure connectivity, and deterministic network timing.
For engineers reviewing the TM4C129CNCZADI3R datasheet, TM4C129CNCZADI3R pinout, TM4C129CNCZADI3R application, or TM4C129CNCZADI3R equivalent, key selection criteria include integrated 10/100 Ethernet PHY, dual USB interfaces (OTG + device), hibernation module with RTC and tamper detection, and support for TivaWare™ software stack in resource-constrained edge nodes.
Technical Context
The TM4C129CNCZADI3R implements a full-featured ARM Cortex-M4F core with single-precision FPU and memory protection unit (MPU), enabling deterministic floating-point math and secure task isolation in multitasking RTOS environments. It integrates a dedicated hibernation module with battery-backed RTC, tamper-detection inputs, and 2 KB of hibernate RAM.
Its system-level integration includes a 10/100 Ethernet MAC with integrated PHY (no external magnetics required), dual USB controllers (one OTG-capable with internal transceiver), and μDMA supporting 32-channel arbitration for zero-CPU peripheral-to-memory transfers - critical for high-throughput sensor aggregation and protocol bridging.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TM4C1294NCPDTI3R | Same core and peripherals but in 128-pin TQFP; lacks integrated Ethernet PHY (requires external PHY); 512 KB Flash, 256 KB SRAM. | Suitable where Ethernet is optional or implemented externally; lower pin count eases routing but increases BOM and layout complexity for Ethernet. | Select when Ethernet PHY integration is unnecessary and smaller footprint is prioritized over PHY cost/complexity savings. |
| STM32H743VIT6 | ARM Cortex-M7 @ 480 MHz, 2 MB Flash, 1 MB SRAM, no integrated Ethernet PHY; supports external Ethernet via RMII/MII; includes JPEG codec and DSI. | Better for high-performance vision or UI applications; requires external PHY and magnetics for Ethernet; lacks hibernation module with tamper detection. | Choose for compute-intensive tasks beyond TM4C129CNCZADI3R's capability, accepting added Ethernet BOM and missing hibernation security features. |
Compared with TM4C1294NCPDTI3R, the TM4C129CNCZADI3R delivers integrated Ethernet PHY and larger Flash, reducing system cost and design risk for wired industrial nodes; versus STM32H743VIT6, it trades raw CPU speed for built-in connectivity, ultra-low-power hibernation, and hardware crypto - optimizing for secure, connected edge control rather than multimedia throughput.

FAQ
What is the operating temperature range for the TM4C129CNCZADI3R?
The TM4C129CNCZADI3R is specified for industrial operation from –40°C to +105°C ambient temperature. This extended range ensures reliable performance in factory automation, outdoor infrastructure, and motor control environments where thermal stress is common. The device's thermal pad and LQFP package support effective heat dissipation under continuous 120 MHz operation. All electrical parameters in the SPMS438B datasheet are guaranteed across this full range.
Does the TM4C129CNCZADI3R include an integrated Ethernet PHY?
Yes, the TM4C129CNCZADI3R integrates a full IEEE 802.3-compliant 10/100 Ethernet PHY with MII and RMII interface support. This eliminates the need for an external PHY IC and associated magnetics, reducing BOM cost and PCB area. The PHY supports IEEE 1588 Precision Time Protocol for time-synchronized networking, and its registers are memory-mapped within the microcontroller's address space for direct software control.
What cryptographic algorithms does the TM4C129CNCZADI3R hardware accelerator support?
The TM4C129CNCZADI3R includes dedicated hardware accelerators for AES-128/256 (ECB/CBC/CTR/GCM), DES/3DES, SHA-1/224/256, and MD5. These engines operate independently of the CPU, enabling high-throughput encryption (e.g., >20 MB/s AES-256) and offloading TLS handshake operations. Key scheduling and data path are fully hardware-managed, ensuring side-channel resistance and deterministic latency.
How much hibernate RAM does the TM4C129CNCZADI3R provide, and what features does its hibernation module include?
The TM4C129CNCZADI3R provides 2 KB of battery-backed hibernate RAM, retained during deep-sleep modes drawing less than 1.5 µA. Its hibernation module includes a precision RTC with calendar support, three tamper-detection inputs with event logging, VBAT monitoring, and wake-on-RTC alarm or external GPIO. This enables long-term unattended operation in battery-powered sensor nodes while preserving critical state and time integrity.
Is the TM4C129CNCZADI3R pin-compatible with other Tiva C Series microcontrollers?
No, the TM4C129CNCZADI3R is not pin-compatible with other Tiva C Series devices due to its unique 144-pin LQFP package and integrated Ethernet PHY pinout (e.g., EPH0–EPH7). While functional similarities exist with TM4C1294NCPDTI3R, that part uses a 128-pin TQFP and lacks PHY pins. Migration requires PCB redesign; however, software compatibility is high via TI's TivaWare™ driver library and CMSIS abstraction layer.
