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.","metaTitle":"Texas Instruments TM4C129ENCPDTI3R Tiva C MCU, 120 MHz, 1 MB Flash","metaDescription":"Texas Instruments TM4C129ENCPDTI3R 32-bit ARM Cortex-M4F MCU, 120 MHz, 1 MB Flash, 256 KB RAM, Ethernet MAC+PHY, USB OTG, CAN, -40 to 85°C, 128-TQFP.
