The LatticeMico32™ is a 32-bit Harvard, RISC architecture "soft" microprocessor, available for free with an open IP core licensing agreement. The LatticeMico32 provides the visibility, flexibility and portability that you expect in an open source hardware design. Everything you need is provided, including software development tools (via LatticeMico™ System) and evaluation boards to try out your designs in hardware.
By combining a 32-bit wide instruction set with 32 general purpose registers, the LatticeMico32 provides the performance and flexibility suitable for a wide variety of markets. Using a RISC architecture, the core consumes minimal device resources, while maintaining the performance required for a broad application set. To accelerate the development of microprocessor systems, several optional WISHBONE compatible peripheral components may be integrated with the LatticeMico32.

Lattice has pre-defined a number of its development boards as platforms within the LatticeMico System Software. This allows you to rapidly start developing LatticeMico32 based systems on these boards. The following boards have been developed:
Lattice develops designs that demonstrate the use of the LatticeMico32 for a variety of system level applications. The following demonstrations are currently supported.
This demonstrates 100Mbps operation of the Tri-Speed Ethernet MAC IP core on a LatticeMico32 Development Board for LatticeECP2 by using a web server in conjunction with the open-source Lightweight IP (lwIP) network stack.
This demonstrates the gigabit capability of the Tri-Speed Ethernet MAC IP core on a LatticeECP2 Advanced Board by using a web server in conjunction with the open-source Lightweight IP (lwIP) network stack.
This demo for the LatticeMico32 runs on a LatticeMico32 Development Board for LatticeECP2 and uses the DDR SDRAM Controller IP core. The DRAM is partitioned and stores LatticeMico32 code in one section and VGA graphics information in another section.
