Key Differentiators
- Integrated Ethernet MAC+PHY (vs TM4C1292NCPDTI3)
- Higher peripheral count (vs TM4C1292NCPDTI3)
- Code compatibility across Tiva C Series (vs TM4C129DNCPDTI3)
Design Notes
The TM4C1294NCPDTI3 operates at 3.3V. Use a low-dropout regulator (LDO) with adequate current rating, such as the TPS7A84, to supply the MCU. Place 100nF decoupling capacitors close to each VDD pin and a 10uF bulk capacitor near the power input. Ensure the core voltage (VDDC) is properly filtered with a 1uF capacitor to ground.
For the 128-TQFP package, use a 4-layer PCB with a solid ground plane. Route high-speed signals like Ethernet and USB with controlled impedance (e.g., 50 ohms for Ethernet). Keep analog and digital grounds separate and connect at a single point. Place the crystal oscillator close to the OSC pins and avoid routing other signals near it.
The TM4C1294NCPDTI3 in TQFP package dissipates heat through the leads and PCB. For high-current applications, ensure adequate copper pour on the PCB to aid heat dissipation. The maximum junction temperature is 105Β°C, so calculate power dissipation and ensure ambient temperature stays within limits. Use thermal vias under the exposed pad if available.
