Cmsemicon Semiconductor has entered the memory market with the launch of its first low-power SPI NOR Flash chip series, expanding beyond its traditional focus on microcontrollers. The move adds a dedicated non-volatile memory line to the Shanghai-listed company’s portfolio and supports its broader strategy of offering tightly coupled MCU and memory solutions for compact, power-sensitive devices.
New SPI NOR Flash Series
The new series debuts with a 4 Mbit SPI NOR Flash device positioned for small-capacity storage needs in embedded and IoT designs.
The chip features a page-based architecture with multiple erase modes, high-speed SPI read/write capability, low power consumption, and data retention without power, making it suitable for code storage, configuration data, and companion storage alongside MCUs and modules.
Typical target applications include embedded MCU program storage, compact smart hardware, low-power IoT terminals, and peripheral or module-side storage where cost and energy budgets are tightly constrained.
First Substantive Step Into The Non-Volatile Memory Segment
The launch closes a gap in Cmsemicon’s Flash product stack and marks its first substantive step into the non-volatile memory segment, a move that complements its established strength in MCU design.
Positioning the product as part of its “MCU+” strategy, the company aims to pair its controllers with in-house memory to offer more integrated solutions for consumer electronics, smart home appliances, industrial control, and automotive-related systems.
By adding NOR Flash, Cmsemicon can capture more bill-of-material value in end devices while differentiating on system-level performance, power efficiency, and cost optimization versus relying solely on third-party memory suppliers.
Key Comments
A Cmsemicon spokesperson said the new SPI NOR Flash family is “an important milestone in our MCU+ roadmap, enabling customers to source controllers and reliable non-volatile storage from a single vendor while keeping power and cost under tight control.”
The company emphasized that entering NOR Flash is not a one-off move, noting that this first 4 Mbit device “lays the foundation for a broader low-power Flash portfolio tailored to IoT, smart appliances, and industrial scenarios where every microwatt and cent matters.”
Management also indicated that the new product is expected to “enrich our product mix, open new application scenarios, and create incremental growth opportunities as the domestic memory ecosystem becomes more competitive.
