Overview

Lattice provides soft RISC-V CPU IP cores designed for implementation within their low-power FPGAs. These cores allow developers to add flexible control and processing capabilities to their FPGA designs. The offerings include a 32-bit RISC-V MC (Microcontroller) core with optional peripherals like timers and interrupt controllers. This enables the creation of complete System-on-Chip (SoC) designs within the FPGA fabric, ideal for control, interface bridging, and system management tasks.

✨ Key Features

  • 32-bit RISC-V (RV32I/EMC) CPU core
  • Synthesizable soft IP for Lattice FPGAs
  • Configurable with optional timer and interrupt controller
  • Low resource utilization
  • Integrates with Lattice Propel design environment

🎯 Key Differentiators

  • Based on the open RISC-V standard
  • Optimized for low-power Lattice FPGA architectures
  • Ease of use with the Lattice Propel design environment

Unique Value: Provides a free, open-standard, and easy-to-use CPU for adding flexible software-based control to power-efficient Lattice FPGA applications.

🎯 Use Cases (5)

System control and management in a larger system Motor control and industrial automation Sensor fusion and data aggregation Interface bridging (e.g., SPI to I2C) Implementing custom logic with software control

✅ Best For

  • Central controller for a multi-sensor industrial monitoring device
  • Housekeeping processor on a communications board
  • UI controller for a small display

💡 Check With Vendor

Verify these considerations match your specific requirements:

  • High-performance computing
  • ASIC designs (this IP is optimized for Lattice FPGAs)
  • Applications requiring 64-bit processing

🏆 Alternatives

Arm Cortex-M1/M3 for FPGAs Xilinx MicroBlaze Intel Nios II

Offers an open-standard (RISC-V) alternative to proprietary soft processors like MicroBlaze and Nios II, avoiding vendor lock-in for the instruction set architecture.
