Product details

It carries 512 KB of Flash, 256 KB of RAM, and 6 KB of EEPROM, sized for firmware stacks that include an Ethernet TCP/IP or CANopen node without external memory. Operating from -40 to 105 °C, the TM4C129EKCPDTT3 is rated for the extended-temperature environments you find in outdoor telecom cabinets, engine compartments, and factory floors with no air conditioning.

120 MHz Cortex-M4F — what it buys you

The 512 KB Flash and 256 KB RAM partition naturally: the lower 256 KB for the application image and bootloader, the upper 256 KB for a firmware-over-Ethernet update buffer, with the 6 KB EEPROM holding calibration constants and node ID. No external serial Flash needed unless you are logging waveform captures.

Frequently asked questions

What is the closest pin-compatible alternative to TM4C129EKCPDTT3?

Within the Tiva C TM4C129x family, parts sharing the same 128-TQFP footprint and peripheral set (Ethernet, dual CAN, USB OTG) are pin-compatible across Flash and RAM density options. Check the TM4C1294NCPDT or TM4C1297NCZAD for higher Flash/RAM variants that drop into the same board layout.

What compliance documentation does TI provide for TM4C129EKCPDTT3?

Texas Instruments provides RoHS and REACH compliance declarations for the Tiva C series. The part is lead-free and the 128-TQFP package is compatible with standard reflow profiles.
