SD NAND and STM32 series successful experience sharing [Copy link]

For MCU, the all-round evolution of integration, cost, power consumption and security can meet the endless market demand. I believe that many engineer friends have used a classic series of MCU - SMT32 series. Today I will mainly talk about the demand for storage chips of STM32 series. In the past, it was basically enough to use built-in E2PROM or external NOR Flash. Due to the rise and development of the Internet of Things, the application of STM32 series has become more and more extensive, resulting in large-capacity storage requirements for storing audio, pictures (GUI), video cache, protocol stack, etc. In this scenario, it can be said that SD NAND and STM32 series are the best partners.

First of all, in terms of the architecture of SD NAND, in simple terms, it uses the NAND Flash (SLC NAND) with the longest service life and the most stable performance. The MCU is equipped with a Flash controller and firmware for NAND Flash management, and uses the most universal SD interface (almost all MCUs have SD interface).

In terms of cost, customers can choose the corresponding capacity according to their needs and reduce costs reasonably.

Plus? SD NAND has built-in bad block management, leveling, dynamic and static EDC/ECC management algorithms. This makes the product quality more stable and extends the product life. It also has built-in Flash management algorithms, which allows the MCU to not worry about managing NAND Flash.

In summary, STM32 series and SD NAND are a best match. Among many customers, we often encounter customers who use STM32 series. When combined with SD NAND, it can be said that it can escort their product research and development, saving time, effort and cost.

SD NAND costs money, right?
