The part is built for industrial and infrastructure edge nodes that need a real-time control core and multiple wired fieldbuses on a single die — Ethernet MAC+PHY, two CAN 2.0B controllers, and USB OTG are all on-chip, so a gateway design avoids an external PHY or CAN transceiver on the MCU side. ## Peripheral set for a single-chip gateway Beyond Ethernet and CAN, the connectivity list includes SSI (synchronous serial), I²C, UART/USART with IrDA, and a QEI for quadrature encoder decoding. The 20-channel 12-bit ADC samples at rates suitable for current-sense feedback in a motion-control PWM loop. Brown-out detect and POR are integrated, so an external supervisor is optional for cost-sensitive builds. Housed in a 128-TQFP with a 14x14 mm body and 0.4 mm pitch, the package is hand-solderable in rework and compatible with standard QFP sockets for prototyping. The exposed pad (thermal pad) needs a via-stitched ground plane on the top layer to pull heat out; without it, continuous 120 MHz operation at 105°C ambient pushes the junction toward the limit.","metaTitle":"TM4C129DNCPDTT3R Tiva C ARM Cortex-M4F MCU, 120 MHz","metaDescription":"Texas Instruments TM4C129DNCPDTT3R 32-bit ARM Cortex-M4F MCU with 120 MHz speed, 1 MB Flash, 256 KB RAM, Ethernet, CAN, USB OTG.

The TM4C129DNCPDTT3R is in a 128-TQFP package with 90 I/O; the TM4C129ENCZADT3 uses a 212-BGA package with additional I/O and a different pinout. The BGA variant is chosen when board area is tight and the extra I/O count is needed, but the TQFP version is easier to route, inspect, and rework in prototype and mid-volume production."},{"question":"Does TM4C129DNCPDTT3R have a direct pin-compatible replacement?","answer":"Within the Tiva C TM4C129 family, several density and temperature-grade variants share the same 128-TQFP footprint. The base product number TM4C129 covers a range of Flash and RAM options that are pin-compatible across the package. No single direct-replacement order code is listed as an official cross-reference, but the family's pin compatibility allows a BOM swap between Flash/RAM tiers without a board respin."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TM4C129DNCPDTT3R","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TM4C129DNCPDTT3R when reusing this data.
