AF-R1
A radiation-tolerant RISC-V processor with integrated AI inference.
A power-efficient RV32IM processor with integrated AI inference and architecture-level radiation protection for control and edge compute.
Applications
Use it for satellite control, interfaces, telemetry, and edge decisions.
- Command and data handling for CubeSats and small satellites
- Payload housekeeping, telemetry, and sensor interfaces
- Screening sensor data onboard so less goes to the ground
- Subsystem control that needs radiation tolerance without rad-hard pricing
