Product details
Overview
TM4C129LNCZADT3 from Texas Instruments is an ARM Cortex-M4F-based microcontroller with 120 MHz operation, 1 MB Flash, 256 KB SRAM, integrated Ethernet MAC+PHY, USB 2.0 OTG, and hardware crypto accelerators (AES/DES/SHA/MD5). It serves as a high-integration host controller in industrial gateways requiring deterministic real-time control, secure connectivity, and local protocol bridging.
For engineers reviewing the TM4C129LNCZADT3 datasheet, TM4C129LNCZADT3 pinout, TM4C129LNCZADT3 application, or TM4C129LNCZADT3 equivalent, this page delivers verified electrical specs, package mapping, functional role clarity, and validated alternative options for embedded networking designs.
Technical Context
The TM4C129LNCZADT3 integrates a single-core ARM Cortex-M4F with FPU and memory protection unit (MPU), supporting IEEE-754 single-precision floating-point operations and configurable privilege levels. Its system-level architecture includes a 32-bit AHB bus matrix, μDMA controller with 32 channels, and hibernation module with RTC and tamper detection.
Peripheral integration centers on dual high-speed interfaces: a 10/100 Ethernet MAC with integrated PHY (MII/RMII) and full-speed USB 2.0 OTG with internal transceiver. All serial peripherals-including eight UARTs, four SPIs, and four I²Cs-support FIFO buffering and automatic flow control.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TM4C1294NCPDT | Same core and memory, but 144-pin TQFP package; lacks integrated Ethernet PHY (requires external PHY) | Suitable for space-constrained designs where PHY integration is unnecessary or external PHY already used | Select when board layout accommodates external PHY and higher pin count enables more GPIO or analog resources |
| STM32H743VIT6 | ARM Cortex-M7 @ 480 MHz, 2 MB Flash, no integrated Ethernet PHY; USB HS only with external PHY required | Better raw compute throughput but requires additional components for Ethernet connectivity and secure boot | Choose when application demands higher DSP performance and external PHY is acceptable for cost or flexibility reasons |
Compared with TM4C1294NCPDT and STM32H743VIT6, TM4C129LNCZADT3 uniquely delivers integrated Ethernet PHY + USB OTG + hardware crypto in a 128-pin LQFP, reducing component count and simplifying certification for industrial networking applications.

FAQ
What is the maximum operating frequency of the TM4C129LNCZADT3?
The TM4C129LNCZADT3 operates at a maximum system clock frequency of 120 MHz, derived from its internal PLL with support for multiple clock sources including external crystals, internal oscillators, and USB SOF synchronization. This frequency is fully supported across all operating voltage and temperature ranges specified in the datasheet, enabling deterministic real-time execution for industrial control loops and protocol stacks.
Does the TM4C129LNCZADT3 include an integrated Ethernet physical layer (PHY)?
Yes, the TM4C129LNCZADT3 integrates a full 10/100 Ethernet PHY compliant with IEEE 802.3, supporting both MII and RMII interfaces. This eliminates the need for an external PHY IC, reduces PCB area, lowers BOM cost, and simplifies EMI compliance. The PHY supports auto-negotiation, loopback modes, and link status reporting directly to the MAC layer within the same die.
What cryptographic algorithms are accelerated by hardware in the TM4C129LNCZADT3?
The TM4C129LNCZADT3 includes dedicated hardware accelerators for AES-128/256 (ECB/CBC/CTR/GCM), DES/3DES (ECB/CBC), SHA-1/224/256, and MD5. These engines operate independently of the CPU core, allowing concurrent encryption/decryption and hash computation while the Cortex-M4F executes application code-critical for secure boot, TLS offload, and encrypted firmware updates in the TM4C129LNCZADT3.
What is the hibernation current consumption of the TM4C129LNCZADT3?
In hibernation mode with RTC enabled and battery-backed RAM active, the TM4C129LNCZADT3 draws less than 1 µA typical from the VBAT supply. This ultra-low power state retains register context, RTC time, and up to 6 KB of battery-backed SRAM, enabling rapid wake-up (<100 µs) while extending battery life to multi-year operation in remote sensor and metering applications using the TM4C129LNCZADT3.
Is the TM4C129LNCZADT3 pin-compatible with other Tiva C Series microcontrollers?
No, the TM4C129LNCZADT3 is not pin-compatible with other Tiva C Series devices due to its unique 128-pin LQFP package and integrated Ethernet PHY pins (e.g., ETH0_RX+/−, ETH0_TX+/−). While functional similarities exist with TM4C1294NCPDT, that part uses a 144-pin TQFP and requires an external PHY. Migration requires PCB redesign and signal routing changes specific to the TM4C129LNCZADT3's pinout.
