SAN FRANCISCO Lattice Semiconductor Corp. Monday (July 25) introduced LatticeMico8, an 8-bit “soft” microcontroller core for its LatticeECP, LatticeEC and LatticeXP families of field programmable gate arrays (FPGAs), as well as the recently released MachXO family of crossover programmable logic devices.
Claiming an industry first, Lattice (Hillsboro, Ore.) said it is also providing a new open intellectual property (IP) core license in an effort to encourage user experimentation, development and contributions. The license applies many of the concepts of the successful open source movement to IP cores targeted for programmable logic applications, the company said.
The LatticeMico8 microcontroller is optimized for Lattice architectures and consumes less than 200 look up tables (LUTs) in its smallest configuration, while maintaining a broad feature set, according to Lattice.
Lattice's open IP core license agreement can be downloaded from the the company's Web site. The license agreement addresses specific issues associated with designs targeted toward programmable logic. Lattice said the license preserves the open nature of the core by permitting use alongside proprietary designs and allows hardware implementation and distribution without the need for a license agreement.
Lattice said the LatticeMico8 reference design, including the core, user guide, all tools and demo examples, is available now for immediate download at no charge on the Lattice Web site.
