LM3S2678-IQR50-A0 Description

The Stellaris® series of microcontrollers—the first ARM® CortexTM-M3 based controllers—brings cost-concious embedded microcontroller applications high-performance 32-bit computing. These cutting-edge components provide clients 32-bit capability for a price comparable to older 8- and 16-bit devices, all in a compact packaging.

The Stellaris family's effective performance and wide integration enable the device to be advantageously positioned for applications demanding strong control-processing and connection capabilities while yet being cost-conscious. The Stellaris LM3S2000 series, created for Controller Area Network (CAN) applications, adds Bosch CAN networking technology, the industry standard for short-haul industrial networks, to the Stellaris family. The groundbreaking Cortex-M3 processor is initially integrated with CAN capabilities in the Stellaris LM3S2000 series.
