GigaDevice intros automotive MCU based on Arm Cortex-M33

Staff reporter, Taipei; Jessie Shen, DIGITIMES Asia 0

GigaDevice has developed an automotive-grade MCU based on the Arm Cortex-M33 core, marking its entry into the car-use MCU segment, according to the China-based fabless company.

Codenamed GD32A503, the first series of GigaDevice automotive MCUs are manufactured using 40nm embedded flash memory process, the company said.

GigaDevice's GD32A503 series of MCUs are well suited for the development of automotive electronics applications including body control modules, lighting, smart cockpits, ADAS and power supplies, the company indicated.

The new GigaDevice automotive MCU series have gone through preliminary user verification, and now are available for samples delivering. The series are available in four packages with a total of 10 product models.

GigaDevice has expressed optimism about memory and sensor demand coming from the automotive and industrial sectors in the second half of 2022, but is cautious about demand for consumer electronics applications. GigaDevice is among the world's major NOR flash memory suppliers.

GigaDevice expects its MCU product line to post significant sales growth in 2022, thanks to its deployments in the industrial and automotive segments. Industrial MCUs have now become a major source of GigaDevice's MCU revenue.

GigaDevice specializes in high-performance, general-purpose 32-bit MCUs fabricated using 40nm, 55nm and 110nm process technologies. The company is developing 28nm designs to further expand its MCU offerings.

In addition to GigaDevice, ChipON, Geehy Semiconductor and Fudan Microelectronics are other China-based companies looking to step up their deployments in the automotive MCU segment, according to industry sources in China.

ChipON recently completed its series C2 round of fundraising, less than nine months after the company completed its C1-series fundraising, the sources indicated. With more working capital, ChipON will be working more closely with First Automobile Works (FAW) and other major China-based automobile vendors.

Fudan Microelectronics plans to roll out its automotive MCU series based on the Arm Cortex-M33 core, while Geehy remains focused on industrial and automotive 32-bit MCUs, the sources said.
