TM4C129XNCZADI3 Technical Specifications

TM4C129XNCZADI3 Key Features

• High-performance ARM Cortex-M4F core at up to 120 MHz for deterministic real-time control and DSP-friendly math acceleration.
• Large embedded memory (1 MB flash and 256 KB SRAM) to support larger firmware, secure boot loaders and over-the-air update images.
• Integrated 10/100 Ethernet MAC simplifies networked product designs and reduces need for external controllers.
• Multiple connectivity options (USB OTG, CAN, UART, SPI, I2C) which reduce board complexity and enable protocol consolidation.

Typical Applications

• Industrial Ethernet gateways and protocol converters that require a high-performance core and an onboard 10/100 Ethernet MAC for reliable wired networking across factory floors.
• Secure embedded controllers for building automation systems that need large flash for firmware and OTA updates plus multiple serial interfaces for sensors and actuators.
• Machine control and motor drive supervision where deterministic timing, high-speed ADC sampling and PWM outputs meet real-time control requirements.
• IoT edge devices that aggregate sensor data, perform local processing and forward packets over Ethernet or USB for cloud connectivity and remote management.

TM4C129XNCZADI3 Advantages vs Typical Alternatives

The device combines a floating-point Cortex-M4F core with a larger embedded memory footprint versus many 32-bit microcontrollers. This reduces external memory needs and lowers BOM costs for feature-rich applications. Integrated Ethernet and multi-protocol peripheral sets provide more on-chip connectivity than simpler MCU families, enabling more compact and reliable board designs. Industrial temperature rating and wide I/O count make this part a stronger fit for rugged deployments and higher integration compared to single-protocol controllers.
