Lattice Semiconductor RISC-V CPU IP
The low power programmable leader.
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)
