"多功能单片学习机 NAND FLASH 驱动设计"

Based on a Multifunction SCM learning machine, the design of the NAND FLASH driver encompasses two main components: the multifunction single-chip learning machine and the NAND FLASH storage. This paper first introduces the software/hardware design of the multifunction single-chip learning machine, which utilizes an automatic program switching circuit that enables the same single-chip to run system programs and user programs, thus achieving online code downloads. The learning machine has externally expanded a large number of hardware resources, and the abundant system hardware resources constitute various practical application circuits. Through the universal expansion interface, it is very convenient to simulate external application circuits and expand user application circuits. The paper then focuses on the software/hardware design of the NAND FLASH expansion board, outlining how the multifunction single-chip learning machine achieves the read and write timing of the NAND FLASH. In summary, the design of the NAND FLASH driver based on a Multifunction SCM learning machine combines the hardware and software design of the machine itself, as well as the specific application of the NAND FLASH storage. The automatic program switching circuit allows for efficient program execution, and the expanded hardware resources provide ample support for a variety of application circuits. The design of the NAND FLASH driver showcases the practical utility and versatility of the multifunction single-chip learning machine in enabling the operation of NAND FLASH storage.
