M31 Foundation & Interface Silicon IP

M31 Technology is a Taiwanese silicon IP company that positions itself as an IP boutique. It supplies silicon-proven building blocks so chip designers can avoid developing standard cells, memories and high-speed interfaces themselves, reducing integration risk and time to market.

Its foundation IP portfolio of more than 400 IPs covers standard cell libraries with power, low-power and high-performance kits, memory compilers, PLLs, ADC and temperature sensors and I/O libraries, developed for 15 foundries from 3nm to 180nm. More than 280 interface IPs include USB4, USB 3.2, USB 2.0 and eUSB2 PHYs, PCIe 5.0/4.0 PHYs, MIPI C/D-PHY and controllers, SerDes, LPDDR4, ONFI, DisplayPort and UFS controllers, covering 8 foundries down to 2nm. It also offers IP integration services.

• Standard cell libraries: base libraries with power management, low-power and high-performance kits.
• Memory compilers: configurable on-chip memories for multiple foundries.
• Analog and I/O IP: PLLs, ADC and temperature sensors, general-purpose and high-ESD I/O.
• USB and PCIe PHYs: USB4, USB 3.2, eUSB2 and PCIe 5.0/4.0 PHY IP.
• MIPI and display IP: C-PHY/D-PHY combo, M-PHY, MIPI controller and DisplayPort TX/RX.
• IP integration service: support for integrating USB, MIPI, PCIe and ONFI PHYs and controllers.

A Vietnamese chip startup can license a USB or MIPI PHY for an imaging or IoT SoC. A design services firm can use M31 standard cell and memory compilers on a mature node for cost-sensitive microcontrollers. A local team porting a design between foundries can rely on IP available for both processes.

Chip teams license proven foundation and interface blocks instead of designing and qualifying them in-house. Coverage of 15 foundries for foundation IP gives flexibility in choosing a process. Interface IP silicon-proven on advanced TSMC nodes supports AI, edge and automotive SoCs. Integration services help smaller teams bring PHYs and controllers into their designs.

The move to 3nm and 2nm processes and the growth of AI and automotive chips make licensed IP a larger share of SoC content. Royalties from advanced-node designs are rising for IP vendors. New design houses in Vietnam and Southeast Asia rely on licensed foundation and interface IP to compete without large internal IP teams.

Taiwanese IP company listed on the Taipei Exchange. Received TSMC Specialty IP Partner Awards in 2016 and 2018 to 2025, and Forbes Best Under a Billion recognition in 2023 and 2024. TSMC OIP IP Alliance member since 2012. Reported nearly fourfold growth in advanced-node royalties in August 2026.
