The integrated Ethernet MAC+PHY and USB OTG with Host/Device/OTG support eliminate external PHY and USB controller chips. Ninety GPIOs, 20-channel 12-bit ADC, CAN, and multiple serial interfaces (UART, SPI, I²C, SSI) make this a single-chip solution for motor drives, building automation controllers, and medical equipment panels. A motion-control PWM peripheral and quadrature encoder interface (QEI) are on-chip, so a servo axis can close the loop directly from the MCU. The 120 MHz core provides higher instruction throughput than lower-speed parts, relevant for tight control loops or Ethernet stack overhead. For BOM freeze planning, the base product number TM4C129 covers a range of Flash/RAM and temperature variants. ## Connectivity check: Ethernet and USB onboard Yes — the TM4C129EKCPDTI3 integrates both an Ethernet MAC with integrated PHY and a USB OTG controller. The Ethernet PHY is on-chip, but external magnetics are still required on the board.","metaTitle":"Texas Instruments TM4C129EKCPDTI3 Tiva C MCU, 120 MHz, 512 KB Flash","metaDescription":"TI Tiva C ARM Cortex-M4F MCU, 120 MHz, 512 KB Flash, 256 KB RAM, 6 KB EEPROM, Ethernet MAC+PHY, USB OTG, 90 GPIO, 128-TQFP, -40 to 85°C.
