Function introduction of three internal resources in single chip microcomputer

Here I talk about the internal resources of single-chip microcomputer, and the traditional books about single-chip microcomputer internal structure is different. The internal resources I’m talking about here refer to the things that SCM provides to us as MCU users. To sum up, there are three main resources Flash: program storage space, early microcontroller is […]

How to encrypt HCS12 Series MCU

In HCS12 Series MCU, encryption can be divided into two methods: complete encryption and encryption using password. These two encryption methods are used in different occasions according to the needs of users. Full encryption The so-called complete encryption is to completely protect the chip and shield all read operations of the chip. In MC9S12DP256, encryption […]

Bootstrapping method of flash program based on DSP chip

Authors: Chen ruozhu, Hu Jinping, Li Zhanming With the rapid development of digital signal processing technology, DSP is widely used in various digital signal processing systems. The program code must be stored in nonvolatile memory if the final system is to run without emulator. Flash is a kind of memory that can be used for […]

Design of a power down data access scheme based on flash kflashfile

kFlashFile 1、 Introduction Kflashfile is a lightweight file data storage scheme based on NOR flash, which is used for projects that need to save power-off data. Kflashfile is mainly designed for i.mxrt series, but its layered framework design makes it easy to transplant to other MCU platforms. Kflashfile is divided into three layers in design […]

What is pslc NAND flash

NAND flash structure the internal organization of NAND flash is composed of blocks and pages. Each block contains multiple pages For those cost sensitive projects, designers sometimes regard MLC NAND as an alternative, which has high capacity and low cost. However, MLC NAND has low durability (about 1 / 20 of SLC NAND), high bit […]
