There is a parameter Tsrc, which is called SDRAM Semi Row Cycle Time in the manual. But I still don't understand what it is used for. Please help explain it to me, thank you....
Designs based on digital signal processors (DSPs) are particularly vulnerable to intrusion if the DSP does not have adequate security capabilities. In many applications, advanced security features can...
I couldn't find a download link for this chip's information on the official website. I found some second-hand SDKs online, but I'm not very reassured. Is there an official channel to obtain this infor...

Today I spent half a day on the loopback mode of MIBSPI. As a beginner, there are many things worth reflecting on. I usually read a lot of technical posts in the forum and benefited a lot. Therefore, ...
Preface
Sleep apnea is a very common sleep breathing disease. According to research, about 24% of adult men and 9% of adult women, or more than 2 million people, suffer from this disease ...[Details]
This article introduces a miniature home electrocardiograph. The instrument has powerful functions: display monitoring, storage, playback, printing, record management, power alarm, telephone or Intern...[Details]
As a single-host multi-slave bus system, the number of slave devices that can be connected to a 1-Wire bus is almost unlimited. In order to avoid logical conflicts, the 1-Wire bus interfaces of all...[Details]
In the field of software development, the most critical but also the most unpredictable phase is the debugging phase. There are many factors that play a role in the process of software debugging, a...[Details]
WiMax technology needs to demonstrate its advantages in specific application scenarios in order to gain market recognition, which requires application testing to measure system performance para...[Details]
Complex circuits and 3D EM simulation tools have reached a point where complex system-level behavior can be simulated before fabrication. Performing EM simulations simultaneously with circuit simul...[Details]
Most
embedded
systems are powered from a 48V backplane. This voltage is typically stepped down to a lower intermediate bus voltage of 24V, 12V, or 5V to power the circuit board racks withi...[Details]
A financial analyst pointed out that the signal reception problems of Apple's 3G iPhone may be caused by some defective chips.
Richard Windsor, an analyst at Nomura Securities, said in a resea...[Details]
The microwave multifunctional therapeutic device uses microwave radiation for heating treatment, which can achieve the effects of sterilization and blood circulation. Using microwaves to directly c...[Details]
Abstract: This paper introduces the controller, interface, display principle and driving method of the handheld computer LCD display based on the SA1110 microprocessor. Combined with the HPC projec...[Details]
FSK (Frequeney-Shift Keying) uses carriers of different frequencies to transmit digital signals. FSK signals have the advantages of strong anti-interference ability and long transmission distance, and...[Details]
Focus shift problem
Visible light and infrared light have different wavelengths, so the imaging focus is not on the same plane, which results in a clear image under visible light condition...[Details]
Today, the value of electronic components in cars accounts for 15-20% of the total vehicle. In the future, as more safety electronic devices, fuel consumption and fuel emission control electronic s...[Details]
Analysis of automotive sensor testing requirements
At present, the control system used in automobiles can be functionally divided into three parts: sensor unit, control unit and execution ...[Details]
In the past one or two years, driven by Apple's iPhone, the smartphone market has expanded rapidly. An important feature of portable products such as smartphones is that they have more and more fun...[Details]
