This means the only sourcing channel is the independent distribution and surplus market. For a BOM that depends on this part, the procurement strategy is to secure remaining inventory through brokers or plan a redesign to a current-generation Cortex-M4 or M7 device with equivalent Ethernet and CAN peripherals. ## Peripheral set: Ethernet MAC plus CAN in one package Includes CANbus and Ethernet connectivity.","metaTitle":"LM3S8733-EQC50-A2 Stellaris ARM Cortex-M3 MCU, 50MHz","metaDescription":"Texas Instruments LM3S8733-EQC50-A2: 32-bit ARM Cortex-M3 at 50MHz with 128KB Flash, 64KB RAM, Ethernet MAC + CAN.
