Product details

At 120 MHz with a single-cycle multiply-accumulate and floating-point unit, this core handles PID loops at tens of kilohertz and can run a lightweight TCP/IP stack without a dedicated network coprocessor. The 256 KB SRAM is enough for two full Ethernet frame buffers plus a modest RTOS heap; the 6 KB EEPROM emulation space holds calibration constants and MAC addresses without external serial EEPROM.

For BOM freeze or second-source planning, the base product number TM4C129 covers a family of density and peripheral variants with the same 128-TQFP footprint, so a pin-compatible swap to a lower-Flash sibling is possible if the firmware fits.

Frequently asked questions

What is the closest pin-compatible alternative to TM4C129ENCPDTI3R?

The TM4C129 family shares the same 128-TQFP footprint and pinout across Flash density options (e.g., TM4C1294NCPDT with 512 KB Flash). A pin-compatible swap is possible if the firmware fits the smaller memory, but verify the peripheral set matches your application.

What is TM4C129ENCPDTI3R's listed speed?

The core processor runs at 120 MHz, which is the maximum CPU clock for the Tiva C series with the ARM Cortex-M4F core.

What compliance documentation does this brand provide for TM4C129ENCPDTI3R?

Texas Instruments provides RoHS and REACH compliance documentation for this part. The 128-TQFP package is lead-free and compatible with lead-free reflow profiles.
