Weeroc Readout ASICs & Space-grade ICs

Weeroc is a fabless IC design company headquartered in Villebon-sur-Yvette, France, with roots in microelectronics for particle physics. It designs programmable ASICs, turnkey photodetection modules and custom ICs for harsh environments, for customers that need to read very weak or very fast signals from detectors. Its Malaysian arm, Weeroc Space Sdn Bhd, works on radiation-hardened chips at the Malaysia Semiconductor IC Design Park.

The product range includes readout chips such as Liroc, Temporoc, Radioroc 2, Poproc and Psiroc with time-of-flight and single-photon capabilities, turnkey modules that combine readout chips with sensors and software, and radiation-hardened circuits for space qualification. Weeroc Space taped out a chip in April 2026 and in October 2026 presented a power controller chip for satellites and space systems.

• Readout chips: Liroc, Temporoc, Radioroc 2, Poproc and Psiroc for photodetector signals.
• Timing and photon counting: time-of-flight and single-photon capabilities.
• Photodetection modules: turnkey modules combining readout chips, sensors and software.
• Space-grade ICs: radiation-hardened circuits for space qualification.
• Custom IC design: from early concept through qualified silicon.
• System design: integration of hardware, software and firmware.

A Vietnamese satellite or space research team can source radiation-tolerant chips and power controllers for small satellites. A medical imaging or nuclear monitoring equipment developer can build detectors on Weeroc readout ASICs. Research institutes can co-develop custom readout chips for physics or quantum experiments.

Instrument makers can use off-the-shelf programmable readout ASICs instead of designing front-end electronics for photodetectors from scratch. Turnkey modules combine chip, sensor and software, shortening development of imaging and detection systems. Radiation-hardened designs address satellites and other harsh environments. Its client list includes Airbus, CNES, NASA JPL and CERN.

Small satellite constellations, medical PET imaging, LiDAR and quantum technologies all need compact, low-noise readout electronics and radiation-tolerant chips. Southeast Asian countries, including Malaysia and Vietnam, are building space and semiconductor programmes and seeking design partners that can transfer know-how locally.
