Luminary Micro, Inc. designs, markets and sells ARM Cortex-M3-based microcontrollers (MCUs).  Austin, Texas-based Luminary Micro is the lead partner for the Cortex-M3 processor, delivering the world's first silicon implementation of the Cortex-M3 processor.  Luminary Micro's introduction of the award-winning Stellaris® family of products provides 32-bit performance for the same price as current 8- and 16-bit microcontroller designs.  With entry-level pricing at $1.00 for an ARM technology-based MCU, Luminary Micro's Stellaris product line allows for standardization that eliminates future architectural upgrades or software tools changes.

Luminary Micro is a private company and was founded in 2004. The company closed its first private funding in February 2005, and announced its second private funding round in June 2006. The company’s executive management team has a wealth of combined experience in start-ups and established companies, in creating new markets, in developing new products, and in gaining product mindshare. This depth of experience and first-hand knowledge of the founders’ accomplishments led ARM to select this young start-up as its lead partner–the first time in history that ARM had a start-up as the lead partner on a processor core development.
