The industrial temperature range (-40 to 85°C) suits it for factory automation, motor control, and building-management gateways where a single chip handles both control and Ethernet connectivity. ## Connectivity set — CAN and Ethernet on one die CAN and Ethernet integration allows a single MCU to bridge a CAN-based machine network to a plant Ethernet backbone without an external gateway chip. The 38 GPIOs leave enough headroom for local I/O and display control alongside the two network interfaces. ## Package and supply voltage The 100-LQFP (14x14 mm) package is surface-mount and suitable for reflow assembly. The core and I/O operate from a single 2.25 V to 2.75 V supply.","metaTitle":"LM3S8938-IQC50 Stellaris ARM Cortex-M3 MCU, 50 MHz, 256 KB Flash","metaDescription":"LM3S8938-IQC50 Stellaris ARM Cortex-M3 MCU, 50 MHz, 256 KB Flash, 64K x 8 RAM, CAN/Ethernet, -40 to 85°C.
