The 256 KB SRAM provides enough buffer space for Ethernet packet queues and double-buffered display frames without starving the control loops. The 6 KB EEPROM is useful for calibration constants and MAC addresses that must survive a firmware update. The TM4C129ENCPDTI3 is in an end-of-life (EOL) stage. The manufacturer has issued a last-time-buy notice, and new-production allocations are closed.","metaTitle":"Texas Instruments TM4C129ENCPDTI3 Tiva C ARM Cortex-M4F MCU, 120 MHz","metaDescription":"Texas Instruments TM4C129ENCPDTI3 Tiva C series ARM Cortex-M4F MCU, 120 MHz, 1 MB Flash, 256 KB RAM, Ethernet/CAN/USB, -40°C to 85°C, 128-TQFP.
