拓展存储领域,中微半导推出首款非易失性存储芯片

Core Viewpoint - The company, Zhongwei Semiconductor, is officially entering the Flash memory market with the launch of its first non-volatile memory chip, the CMS25Q40A, which is a low-power SPI NOR Flash chip with a capacity of 4M bits [3][4]. Product Details - The CMS25Q40A chip features a storage array divided into 2048 programmable pages, each with a capacity of 256 bytes, allowing for a maximum of 256 bytes of data to be written in a single programming operation [3]. - It supports various erasure methods, including 1KB sector, 4KB sector, 32KB block, 64KB block, and full chip erasure, emphasizing its low cost, low power consumption, high-speed SPI read/write, and data retention during power loss [3][4]. - The chip operates on a single power supply ranging from 1.65V to 3.6V and supports standard Serial Peripheral Interface (SPI) with compatibility for dual and quad output modes, achieving a maximum SPI clock frequency of 120MHz [4]. Application Scenarios - The product is designed for small storage needs, applicable in embedded MCU program storage, small smart hardware configuration storage, low-power IoT terminal storage, and peripheral/module storage [4]. - The launch of the CMS25Q40A is a significant step in the company's "MCU+" strategy, filling a product gap in the Flash sector and marking a substantial move into the storage field [4]. Strategic Implications - The introduction of this new product enriches the company's product matrix and expands application scenarios, enhancing its overall capability in smart control solutions [5]. - This development is expected to strengthen the company's competitive edge and support the exploration of new storage markets, providing a solid foundation for future growth [5].
