Overview

The TM4C1294NCPDTI3 is a high-performance ARM Cortex-M4F based microcontroller from the Tiva C Series featuring an integrated Ethernet MAC and PHY. Operating at 120MHz, it provides 1MB of Flash and 256KB of SRAM, making it suitable for applications requiring both real-time control and robust networking capabilities.

Why Choose This Part

This MCU stands out by integrating the Ethernet PHY directly onto the silicon, significantly reducing PCB complexity and BOM cost for networked designs. It also includes 6KB of dedicated EEPROM for high-endurance data logging and a hardware floating-point unit for complex mathematical computations at 120MHz.

Applications

Industrial Gateways
Utilizing the integrated Ethernet MAC/PHY and CAN controllers to bridge industrial fieldbus networks to corporate Ethernet infrastructures.
Connected Motion Control
Leveraging the Motion Control PWM peripherals and high-speed ADC for precise motor synchronization across a networked environment.
Smart Grid Equipment
Processing power monitoring data with the floating-point unit and communicating via the extensive serial interface options including 8 UARTs.
Building Automation
Managing HVAC or lighting systems using the large 90-pin I/O count and internal EEPROM for non-volatile configuration storage.
