Key Differentiators
- Integrated Ethernet MAC+PHY (vs TM4C1292NCPDTI3)
- 1 MB Flash and 256 KB SRAM (vs TM4C1294KCPDTI3R)
- Industrial temperature range (vs TM4C1294NCPDTT3)
Design Notes
The TM4C1294NCPDTI3 operates at 3.3V. Ensure a stable power supply with adequate decoupling capacitors (100nF and 10uF) placed close to the VDD pins. The device has multiple power domains; refer to the datasheet for proper connection of VDDA and VDDC pins.
For the 128-pin TQFP package, use a 4-layer PCB with a solid ground plane. Keep high-speed signals like Ethernet and USB traces impedance-controlled (e.g., 50 ohms for Ethernet). Place the crystal oscillator close to the OSC pins and keep traces short to minimize parasitic capacitance.
Ensure the JTAG/SWD pins are not left floating during programming. The device has multiple boot modes; configure the BOOTCFG register correctly to avoid unexpected boot behavior. Also, note that the 'I3' suffix indicates industrial temperature range; do not exceed the absolute maximum ratings.
Compliance Information
RoHS compliant per TI product page. Not AEC-Q100 qualified.
