TM4C129CNCPDTT3 Technical Specifications

TM4C129CNCPDTT3 Key Features

• High?performance Cortex?M4F core at 120 MHz for real?time DSP and control tasks; delivers faster signal processing than typical 32?bit MCUs.
• Integrated 10/100 Ethernet MAC enables direct network connectivity and offloads TCP/IP stack traffic to free CPU cycles for application logic.
• On?chip 1 MB flash and 256 KB SRAM reduce external memory needs and simplify secure boot, logging, and field upgrades.
• Multiple serial interfaces (USB Host/Device/OTG, CAN, I2C, SPI, UART) for easier integration with sensors, actuators, and fieldbus nodes.
• High channel count 12?bit ADCs and many GPIOs support dense sensor arrays and analog signal acquisition without external converters.
• Industrial temperature support and high pin?count package improve reliability and permit dense I/O routing on complex control boards.

Typical Applications

• Industrial Ethernet controllers and gateway devices that require deterministic control with integrated 10/100 Mbps networking and local I/O aggregation for machine automation.
• IoT edge nodes that perform local data filtering and secure updates, using on?chip 1 MB flash for firmware and storage while connecting over Ethernet or USB.
• Motor control and drives where the Cortex?M4F DSP capabilities and multiple PWM/ADC channels enable precise closed?loop control and real?time sensor feedback.
• Embedded routers and communication modules that combine dual CAN, serial interfaces, and Ethernet to bridge automotive or industrial buses to IP networks.

TM4C129CNCPDTT3 Advantages vs Typical Alternatives

The device integrates more on?chip memory and network peripherals than many general?purpose MCUs, offering higher integration and fewer external components. With a 120 MHz Cortex?M4F core plus dedicated Ethernet and USB support, it handles both control and communications in a single package. This reduces BOM cost, board area, and system complexity when compared to using separate MCU plus network controller solutions.
