FAQ

Does TM4C1292NCPDTT3R include an integrated Ethernet PHY?

No, the TM4C1292NCPDTT3R integrates only the Ethernet MAC layer. It requires an external PHY chip (e.g., DP83848 or LAN8742A) connected via MII or RMII interface. The TM4C1292NCPDTT3R provides all necessary control, status, and data signals for seamless PHY interfacing without glue logic.

What is the maximum operating frequency of TM4C1292NCPDTT3R?

The TM4C1292NCPDTT3R operates at a maximum system clock frequency of 120 MHz, derived from its internal PLL with support for multiple clock sources including external crystal (4–25 MHz), internal oscillator, or precision internal oscillator (PIOSC). This frequency is fully supported across the entire industrial temperature range (–40°C to +105°C).

Is TM4C1292NCPDTT3R pin-compatible with other Tiva C Series MCUs?

Yes, the TM4C1292NCPDTT3R shares the same 128-pin LQFP (PDT) package footprint and pin mapping with other members of the TM4C129x family, including TM4C1294NCPDTT3R and TM4C1290NCPDTT3R. This allows hardware reuse across variants differing primarily in Flash/SRAM size and peripheral enablement.

Does TM4C1292NCPDTT3R support CAN FD?

The TM4C1292NCPDTT3R implements CAN 2.0B controllers only. While CAN FD frame formatting can be implemented in software, the hardware does not support CAN FD bit rates, arbitration phase extensions, or payload lengths beyond 8 bytes. For native CAN FD, consider newer TI devices such as the AM263x or MSP430FRxx series with CAN FD IP.

What debug interfaces are supported by TM4C1292NCPDTT3R?

The TM4C1292NCPDTT3R supports JTAG and SWD (Serial Wire Debug) interfaces via dedicated pins (TCK, TMS, TDI, TDO, nSRST, SWDIO, SWCLK). It is fully compatible with TI's XDS110 and third-party debug probes supporting ARM CoreSight, enabling full-featured debugging, flash programming, and real-time trace via SWO.
