STMicroelectronics has announced the launch of a new computer chip aimed at the rapidly expanding AI data centre market. Developed in collaboration with Amazon Web Services (AWS), the photonics chip uses light rather than electricity, which helps increase speed and reduce power consumption in AI data centres. These chips are expected to be used in transceivers, which are crucial components in data centre infrastructure.

As top US software companies plan to invest$500 billion into AI infrastructure, there is rising demand for specialised chips, not only for computing but also for memory, power, and communications applications. ST's new chip targets the communications sector, with a focus on improving the efficiency of transceivers, which are essential in AI data centres. The company also has a collaboration agreement with AWS to deploy this technology in their infrastructure later this year.

ST is working with a leading provider of optical solutions, although the company's name has not been disclosed, to integrate the new chip into next-generation transceivers. The market for such devices, valued at$7 billion in 2024, is expected to grow significantly, reaching$24 billion by 2030. ST will begin mass production of these chips at its facility in Crolles, France.
