GigaDevice

GigaDevice Semiconductor Inc. (SSE: 603986) is a global fabless semiconductor company that designs and supplies non-volatile memory (NVM) devices, 32-bit microcontrollers (MCUs), and sensors. Founded in April 2005 by Yiming Zhu, the company is headquartered in Beijing, China, and has established a worldwide presence with offices in multiple countries to provide local customer support. Zhu, a Tsinghua University alumnus who also studied at Stony Brook College in New York, brought a Silicon Valley-influenced leadership style to the company's foundation.

The company operates on a fabless business model, concentrating on the research, development, and sale of its integrated circuits while outsourcing manufacturing to strategic partners. This approach allows GigaDevice to focus on its core competencies in chip design. Revenue is generated primarily from the sale of its flash memory and microcontroller products. The company serves a wide array of markets, including industrial, automotive, computing, consumer electronics, IoT, mobile, networking, and communications.

GigaDevice's product portfolio is centered around three main categories: Flash memory, MCUs, and sensors. Its flash memory offerings include high-performance SPI NOR Flash and SPI NAND Flash. The company's GD32 MCU family, introduced in 2013, is based on the 32-bit ARM Cortex-M core and has seen significant adoption, with some chips being pin-compatible with STMicroelectronics' STM32 series. In 2019, GigaDevice expanded its MCU lineup with the GD32V series, which utilizes a custom RISC-V core. The sensor division develops human-computer interaction solutions like fingerprint and touch-screen controller chips.

A significant milestone in the company's history was its initial public offering on the Shanghai Stock Exchange in August 2016. In 2015, GigaDevice was part of a consortium that acquired Integrated Silicon Solution Inc., a major producer of NOR flash memory. The company has also been active in strategic acquisitions to enhance its technological capabilities, such as its planned acquisition of a majority stake in Suzhou Syschip Electronics Technology to bolster its battery management technology. In June 2025, the company established a global headquarters in Singapore to enhance its international influence.
