Programming applications of commonly used serial EEPROM (part 3)

SPI busThe serial peripheral interface bus is a three-line serial bus developed by Motorola for data transmission using three lines, which are the sck clock pins, SI data input pin and so data output pin. In addition, the CS chip selection pin can be used to select chips on the same bus, SPI bus has been widely used in EEPROM, single chip microcomputer and various devices. The 25xx series chips in commonly

This is a very simple mini-game: First the computer gives the first integer, then the player bets bet the second integer will be larger or smaller than the first number, the player bets T chips, the computer gives a second number. If the player guesses the right, the system rewards the player T

Analysis of the method of solid-state hard disk and U disk

first, the main control algorithm is not the same SSD is a special algorithm, this algorithm is different from each manufacturer, and is encapsulated in the main control chip. With this algorithm, the data can be distributed evenly to each flash on the SSD, while the speed is increased, the life of the flash is greatly prolonged. More efficient algorithms can be high speed data compression read and write, especially the reading speed can be achieved very high, more efficient algorithm may be f

My interest lies in the Small PCB Board on the back of most hard disks with SATA and power interfaces. This PCB looks like this: We can see that there are four chips on the PCB. Let's talk about these chips: This is a

Analysis and elimination of random crash-hardware maintenance

maintenance statistics, the random fault caused by software causes is about 20% of the total number of failures. Third, the hardware reason Hardware system caused by panic, mainly due to the internal components of the machine quality, compatibility or improper matching caused. Usually includes: 1. Pluggable chip contact failure. There are some pluggable chips on the motherboard bad contact, this kind of failure is very easy to happen in CPU

Which is better for Intel and AMD?

It is well known that assembling a personal computer is incredibly complicated for ordinary people, especially if they don't have any experience. Because of the need to assemble an unusually large number of parts and components together to make it a huge system. But then there are many problems, that is, a set of components are compatible with each other difficult to distinguish, and in addition to the above reasons, but also need to take into account the price, demand and more factors.

One of the storage principles _ storage

roughly how a basic SRAM chip works. SRAM is the abbreviation for "Static RAM", which is named because it does not disappear when the data is deposited (unlike DRAM dynamic random memory, which must be refreshed in a certain amount of time to keep the data stored therein). An SRAM unit is usually composed of 4-6 transistors, and when the SRAM cell is given a state of 0 or 1, it retains that state until the next time it is given a new state or the power is off before it changes or disappears. SR

Four measures to ensure RFID credit card security

The worry about RFID security is not new. However, these concerns grew when the US MRT company and Chase started issuing RFID-enabled credit cards last year. The fear escalated when researchers at the University of Massachusetts announced in October this year that they had breached the credit card RFID security feature. RFID usage So far, RFID chips have been used only for labels of goods, transport containers and livestock. These

Comprehensive comparison between GPON access technology and EPON

cost of the GPON access technology is too high, in addition, it was previously considered that the technology was not mature enough. Which PON is used has always been the focus of debate in the industry. Recently, with the development of optical access networks in China, the competition between GPON access technology and EPON has become lively, and both camps have argued that with the increasing maturity of GPON access technology, recently, it seems that the voice of GPON access technology has
