TM4C129ENCZADT3 Technical Specifications

TM4C129ENCZADT3 Key Features

• ARM Cortex-M4F core with floating-point unit for faster DSP and control algorithms, which reduces cycle counts versus integer-only MCUs.
• Large on-chip memory (1 MB flash, 256 KB SRAM) to support larger firmware images and local data buffering, helping avoid external memory in many designs.
• Integrated dual 10/100 Ethernet MACs for multi-port or switching gateway topologies, enabling more ports without extra PHY controllers.
• Comprehensive peripheral set including USB Host/Device/OTG, CAN, multiple UART/SPI/I2C, ADCs and timers for consolidated system integration and reduced BOM count.

Typical Applications

• Industrial Ethernet gateways and protocol converters where deterministic timing and multiple 10/100 Mbps interfaces connect field networks to control systems over IP.
• Edge controllers for factory automation that require higher compute and memory to run device stacks, local analytics, and secure communications concurrently.
• Smart grid and energy monitoring nodes that need accurate ADC conversion, time-synchronized Ethernet, and local buffering for intermittent upstream connectivity.
• High-integration building automation controllers that replace multiple discrete components by using the MCU’s Ethernet, USB, CAN, and analog peripherals in one package.

TM4C129ENCZADT3 Advantages vs Typical Alternatives

This device offers more on-chip memory and more integrated networking than many mid-range microcontrollers, making it a stronger fit where firmware size and multiple wired interfaces matter. Compared with single-Ethernet or lower-memory MCUs, it reduces external component count and board complexity. The integrated Ethernet MACs and USB support enable higher total system throughput, while the Cortex-M4F core accelerates signal processing tasks versus comparable integer-only cores.
