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.","metaTitle":"Texas Instruments TM4C129EKCPDTT3 Tiva C MCU, 120 MHz Cortex-M4F","metaDescription":"TI TM4C129EKCPDTT3 ARM Cortex-M4F MCU, 120 MHz, 512 KB Flash, 256 KB RAM, 6 KB EEPROM, Ethernet/CAN/USB OTG, 90 GPIO, -40 to 105 °C, 128-TQFP.
