About Nanjing Yitai Microelectronics Technology

Nanjing Yitai Microelectronics Technology Co., Ltd. (also known as EtlChip) is a fabless semiconductor company established in 2022, specializing in high-performance communication chips for automotive and industrial applications. The company was founded by Zhong Jianfeng and is one of the few teams in China with the capability to develop a full stack of in-vehicle Ethernet chip solutions, including both Physical Layer (PHY) transceivers and Time-Sensitive Networking (TSN) Switch chips.

The company addresses the growing demand for high-speed in-vehicle communication driven by advancements in intelligent cockpits and autonomous driving. While the Chinese market for automotive Ethernet chips has been largely dependent on imports from international giants, EtlChip is focused on providing domestic alternatives. Its product portfolio includes industrial Ethernet chips, which are already in mass production, as well as automotive-grade chips. The company has developed China's first gigabit TSN Ethernet Switch chip, matching the performance of leading international products.

EtlChip serves original equipment manufacturers (OEMs) in the automotive sector, with its "Xingchen" series of switch chips and "Shanhai" series of PHY chips being designated for use in commercial vehicles, passenger cars, and L4 autonomous vehicles. The company projects large-scale application of its chips in vehicle models from 2025 to 2026. The business generates revenue through the sale of its chip products.

Since its founding, EtlChip has completed several funding rounds. After an angel and a Pre-A round in 2023, the company secured a Pre-A+ round in April 2024, led by Zhongke Chuangxing (CASSTAR), to fund further R&D and product delivery. More recently, in August 2025, it announced the completion of a nearly CNY 100 million Series A1 financing round co-led by Changjiang Securities Innovation Investment and CAS STAR.
