Its research and development centers are located in both Shenzhen and Hong Kong.
Read full description
The company's business model is centered on the fabless manufacturing strategy, concentrating on the design and sale of high-tech semiconductor products while outsourcing the fabrication process. Its product portfolio is engineered to serve an array of markets, including mobile phones, wearable devices, digital keys, and smart trackers. GiantSemi's technology is applicable in various consumer and commercial sectors such as access control, smart payments, smart homes, and smart cities. The company generates revenue through the sale of its semiconductor chips and system solutions to manufacturers and partners in these sectors.
A key product is the GT1500, a UWB System-on-Chip (SoC). This single-chip solution integrates a radio frequency transceiver, baseband unit, a microcontroller, and other components, operating in the 4 to 9 GHz frequency range. The GT1500 is notable for its small footprint, occupying just 9mm², which makes it suitable for space-constrained applications like wearables and other IoT devices. It is designed to reduce design complexity and bill of materials costs for product developers. The chip is compliant with standards set by the FiRa Consortium and the Car Connectivity Consortium (CCC), ensuring interoperability for applications like digital car keys. In June 2022, its GT1000 chip became the first in China to receive FiRa Consortium certification, with mass production starting in May 2022.
