The 1 MB Flash is sized for firmware images that include an Ethernet bootloader, application code, and a file system. The 256K SRAM supports multiple packet buffers and a moderate heap for dynamic allocation. ## Lifecycle reality — plan the BOM line ## Connectivity and I/O — single-chip gateway capability With Ethernet MAC+PHY, two CAN controllers, and USB OTG on-chip, this MCU eliminates the need for external PHYs or protocol bridge chips in many designs. The 140 I/O lines include dedicated pins for the external bus interface (EBI/EMI), allowing parallel connection to an external SRAM or display controller. The 24-channel 12-bit ADC samples analog inputs from temperature sensors, current shunts, or potentiometers without an external mux.","metaTitle":"TM4C129LNCZADI3R Tiva C ARM Cortex-M4F MCU, 120MHz, 1MB Flash","metaDescription":"TM4C129LNCZADI3R from TI: 32-bit ARM Cortex-M4F MCU, 120MHz, 1MB Flash, 256K RAM, Ethernet+USB+CAN, -40 to 85°C.
