Product details

50 MHz Cortex-M3 with Ethernet and CAN — what this Stellaris part brought to the table

The LM3S8733-EQC50-A2: This was a mid-range connectivity MCU aimed at industrial control, building automation, and networked sensor nodes where both wired Ethernet and CAN bus were needed on a single chip.

Obsolete — no official successor on record

The Stellaris family was acquired with the Luminary Micro purchase and later folded into the Tiva C series, but no direct pin-compatible replacement part number has been assigned. 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.
