How can the new generation of CS sdnand (also known as patch T card) make the old MCU youthful

　　CS A whole new generation SD NAND（ Also known as patch type T card ） How to make the old style MCU Rejuvenate
　　
　　 More and more engineers use CS brand SD NAND, Recently, I encountered some interesting situations . Some engineers came to ask if we could SD NAND Connect to it MCU Of SPI port . Ordinary customers will SD NAND Connect to SDIO. Why do you need SPI Interface ？ These customers use MCU The model is relatively early . Is it related to this ？
　　
　　 After summarizing , There may be two situations ：
　　
　　 First , old MCU, They don't even SDIO Interface , Only SPI Interface . But I want to use mass storage .
　　
　　 secondly ,MCU There is one SD Interface , But the number is very small , For example, there is only one . It is also occupied by other modules , for example wifi modular . But customers still want to use mass storage .
　　
　　 For the above reasons , They want to ask CS Brand SD N??AND Can we solve this problem . in fact , In principle, , As long as the following two conditions are met ：
　　
　　1. MCU Of SPI Interface support SD Agreed SPI Pattern .  SPI The interface can be connected to SD NAND, It can be used normally. . It's a little convoluted , There is a simple and rude way to verify . If you use MCU Of SPI Interface and T The card works properly , So that means MCU have access to SD NAND.
　　
　　2,SD NAND Must be with SPI Mode compatible . However , Many manufacturers in the market have deleted this model for various considerations such as cost .
　　

　　 new generation CS brand SD NAND accord with SPI Pattern , Capacity of 128MB and 512MB. This allows the old MCU Use large capacity memory chips , And the application scenarios of the product can be richer . therefore , It is said that the new generation CS Brand SD NAND Make the old MCU Shine in the second spring .
　　
　　 Welcome customers and friends with the same needs to consult .
