The connectivity block includes Ethernet, SPI, SSI, UART/USART, IrDA, and Microwire — so this part can serve as a networked sensor hub or a fieldbus gateway without an external PHY for the Ethernet MAC. The 46 GPIOs give room for parallel displays or a bank of opto-isolated inputs. ## Obsolete — sourcing reality for the BOM line Texas Instruments lists the LM3S6420-EQC25-A2T as Obsolete. Sourced per RFQ — quantities are lot-specific and confirmed at quote time. No stock-holding claim; each order is verified against the BOM quantity.","metaTitle":"Texas Instruments LM3S6420-EQC25-A2T ARM Cortex-M3 MCU","metaDescription":"Texas Instruments Stellaris ARM Cortex-M3 MCU, 96KB Flash, 32Kx8 RAM, 100-LQFP, -40 to 105°C.
