Ubilite Licenses RISC-V Application Processor IP Core from CAST

RISC-V Summit, Santa Clara, California — November 7, 2023


Semiconductor intellectual property provider CAST today announced that ultra-low-power Wi-Fi chipset developer Ubilite, Inc. has licensed a RISC-V IP core for use as an application processor in Ubilite’s next generation of products.

Ubilite designs and fabricates custom system chips that provide the advantages of Wi-Fi connectivity with ultra-low power consumption equivalent to or less than Bluetooth Low Energy. Their current UBI206 Wi-Fi chip uses a tenth of the power of competing Wi-Fi chipsets, making it ideal for Internet of Things and other battery-powered applications that must wirelessly exchange significant amounts of data. It combines a Wi-Fi 802.11b/g/n radio, media access controller (MAC), power management unit (PMU), memories, a network application processor, and other functions to provide a complete Wi-Fi solution.

Ubilite previously licensed the BA20 Processor Core and a peripherals platform from CAST. The company’s upcoming new Wi-Fi products will now make use of the BA51 Ultra-Low-Power Deeply Embedded RISC-V Processor as an application processor.

“Like Ubilite with Wi-Fi, CAST provides extremely competitive IP core products that are high-quality, complete, and easy to integrate and use,” said Peter Gammel, chief executive officer for Ubilite. “We expect the RISC-V processor core we’ve licensed from CAST to help us maintain — and extend — the advantages of our low-power Wi-Fi SoCs over competing IoT products.”

Sourced from CAST partner Beyond Semiconductor, the BA51 Core is available royalty-free for ASICs or FPGAs. It supports the 32-bit RISC-V instruction set with an ultra-low-power, two-stage pipelined architecture. The processor is full featured yet uses remarkably little power and silicon area, and can run at over 500MHz in 16nm ASIC technologies.
