GigaDevice
GigaDevice Semiconductor Inc. is a Beijing-based fabless chipmaker that designs flash memory, microcontrollers, sensors, and analog products. Its flash memory lines cover SPI NOR, SPI NAND, and Parallel NAND, while its microcontrollers include the GD32 series (ARM Cortex-M3) and the GD32V series (RISC-V). The company was founded in 2005, launching China’s first SPI NOR flash in 2008 and entering the MCU market in 2013.
In 2015, GigaDevice joined Uphill Investment Co. to help acquire Integrated Silicon Solution Inc. (ISSI) for about $731 million, beating Cypress Semiconductor. The Uphill group included eTown MemTek Ltd and several Beijing-backed investors. GigaDevice listed on the Shanghai Stock Exchange in August 2016. It signed the UN Global Compact in June 2023, established its global headquarters in Singapore in June 2025, and completed a secondary listing on the Hong Kong Stock Exchange on January 13, 2026.
The GD32 MCU line is based on the ARM Cortex-M3 core and was introduced in 2013, spanning six product families: Basic, Mainstream, Value, Connectivity, Performance, and Extend, with clock speeds from 48 to 120 MHz. Some GD32 parts are pin-compatible with STMicroelectronics’ STM32. The GD32V line, launched in 2019, uses a custom RISC-V core called the Bumblebee Core, designed by Nuclei System Technology.
