1. Logical bank and Chip WidthAfter explaining the external form of the SDRAM, we should have a deep understanding of the internal structure of the SDRAM. The main concept here is the logical bank. Simply put, the internal structure of SDRAM is a storage array. Because it is a pipe-type storage (such as queuing to buy tickets), it is difficult to achieve random access.The array is like a table. You can fill in the data as a table. Like table search, y

{Tagshow (Event)} "> Minimum MCU {Tagshow (Event)} "> System, or minimum {Tagshow (Event)} "> An application system is a system that can work with a single-chip microcomputer consisting of the least components.For 51 series single-chip microcomputer, the minimum system should generally include: single-chip microcomputer, crystal oscillator {Tagshow (Event)} "> Ci

Single-chip microcomputer and (serial screen) touch screen communication based on Modbus Protocol (graphic)Introduction: Touch screen can be intuitive, vivid display of operating parameters and operating state, and through the touch screen screen can directly modify the system operating parameters, human-machine interaction is good. Touch screen and single-chip communication, the need for a single-

Chip design This business, from the big aspect, mainly divided into analog and digital two chunks, and each large and sub-front and back end, I think most of the students on this is definitely very clear, the following on the digital circuit chat chip design Some things, is the chip design has what to do, this is not a complete system introduction, Just a persona

As the main control unit of the embedded system-single-chip microcomputer, its software is often a micro real-time operating system, and most of them are specially designed for a certain application. The system program is capable of real-time process control or real-time information processing. It must be able to respond to random external events in a timely manner and quickly process the events. However, the time-sharing operating system divides the

When the user encountered a U disk failure will usually use U disk production to repair, but in the U disk volume production operation must master U disk main control chip model before the next operation, then how can you know the main control chip model of U disk? Let's see what the easiest way for us to share is the master. 1, first, plug the need to test the U disk, and then run the

The continued popularity of the smartphone market has also escalated the battle for upstream processors. Recently, the traditional chip manufacturers- -Broadcom, Inc., announced that it will exit the mobile phone communication chip market (baseband processor chip), let people sigh unceasingly. But at the same time, the "upstart" Intel is accelerating the layout

Learning to use single-chip microcomputer is to understand the hardware structure of single-chip microcomputer, as well as the application of internal resources, to learn initialization settings of various functions in the compilation or C language, and to implement programming of various functions. Step 1: use of digital I/O With the button input signal, the Light Emitting Diode shows the output level, you

Before Yan Freescale series single-chip microcomputer is the flagship product developed by feisikar. The former Motorola semiconductor department is one of the world's largest semiconductor companies. It has four R D centers in Beijing, Shanghai, Suzhou and Tianjin, we have established Freescale single-chip microcomputer labs and training cooperation institutions on more than 20 key university campuses in

Serial screen (touch screen) configuration Software + 51 single-chip Modbus RTU Multi-machine serial communication program source codeRealization of the touch screen (serial screen) and SCM communication, mainly to solve the problem of communication protocols. This paper uses the open Modbus Communication protocol to Guangzhou Hmimaker touch screen as host (master), single chip microcomputer as Slave (slave

(a) mobile terminal developmentA mobile phone to achieve the most basic function-call to send text messages, this mobile phone will include the following parts: RF section, baseband section, power management, peripherals, software and so on. Look back at the history of mobile phones:1, Function mobile phone (Feature phone): Only with baseband chip, can only be used to call, send text messages.2, Multimedia Mobile: Use baseband

Hardware: Microprocessor (MPU, up ):A device composed of a computer's processor and a controller integrated into a chip is called a microprocessor, also known as a central processing unit (CPU, central processing uint). a cpu is the brain of a computer system, various logical and arithmetic operations, program execution, and generation of various control signals are implemented. Other components in the computer system are coordinated under the command

The debugging of the algorithm porting encryption chip contains 2 parts: Communication Debugging and Algorithm debugging. Before talking about the communication debugging skills, the next chapter will be the algorithm debugging problems in the analysis and summary, to help customers to complete the debugging smoothly.Frequently asked questions in algorithmic debugging:1. Do not build your own projectWhen porting the algorithm, the customer does not ne

Hello everyone, this is the use of a blog, this article is the ATSHA204A encryption chip configuration, mentioned above, atsha204a encryption chip internal ROM three areas, one is Config zone, one is slot zone, there is an OTP zone, This article not only explains Config zone configuration, but also explains the slot and OTP area configuration method, and unifies the official library to demonstrate the code.

Speaking of the 51 MCU clock first thought about 51 o'clock how to work. Micro-controller to work must have a "power", for 51 single-chip microcomputer, this "power" is the clock source. A 12MHz crystal oscillator is used as the clock source for general applications. Generally the first method is used more often. When the internal oscillation mode is selected, there are two small capacitors next to the crystal oscillator. These two capacitors are call

use of particularly frequent and infrequent variables.In contrast, the 51-core microcontroller storage structure is a bit strange, it has 3 storage space: Program memory space (on-chip, off-chip), off-chip data memory space (64KB), on-chip data memory and special function register space. It has no real register, and i

Recently, Tsinghua Purple, Wuhan New core in the field of memory chips frequently, so that we look at the previously neglected memory chip. For a long time, in the CPU,GPU, baseband and other "advanced" chip spotlight under the cover-up, memory chip has been in obscurity, however, any one involving digital IC products, small to the bank card, big to the server, i

Introduction Flash Memory, also known as flash memory, is a new kind of non-volatile semiconductor storage developed in the late 1980s S. It has the features of Ram and Rom, which can be erased and rewritten online, and keep data intact after power loss. Nor flash is the first kind of flash memory. Compared with other types of flash memory, nor flash has the following advantages: high reliability, fast random reading speed, and single-byte or single-word programming, allows the CPU to directly r
