The debugger I used had no problems and had been using it for a long time. Today, it suddenly stopped recognizing the chip when I was burning it. I reinstalled the TI flash program many times, but it ...
Renesas Technology Corp. today announced the addition of 36 new models to the R8C/Tiny series of small, low -pin-count, high-performance 16-bit microcontrollers with on-chip flash memory. The new mode...
1. What is the concept and structure of thyristor? Thyristor is also called thyristor. Since its introduction in the 1950s, it has developed into a large family. Its main members include unidirectiona...
Can the oldest asynchronous SRAM (without clock, such as IS61LV256AL) be written continuously? That is, set the chip select CE, write signal WE and OE low, and then change the write address and write ...

The hardware circuit principle is shown in Figure 1. In the specific design, each part should consider the anti-interference problem to minimize the impact of interference on the performance of the...[Details]
TD-SCDMA terminal conformance test includes three types of tests: RF index test (reference standard: 3GPPTS34.122), protocol signaling test (reference standard: 3GPPTS34.123) and other tests (refer...[Details]
This summary will introduce the transmitter characteristic test of TD terminal products - uplink power control. According to the 3GPP TS34.122 standard, UE uplink power control is divided into uplink ...[Details]
The small size and low cost of home appliance control boards mean that high-cost materials will not be used in the circuit to solve the electromagnetic interference problem. The interference of hom...[Details]
Multiple Input and Multiple Output (MIMO) technology is arguably the next most important development in wireless communications since the advent of digital communications. Many new wireless commun...[Details]
There are many ways to attenuate signals. The most commonly used method is to divide the voltage using resistors. The common circuits are as follows:
Oscilloscope pre-stage attenuation c...[Details]
Industrial control
often requires multi-channel fault detection and multi-channel command control (this multi-task setting is very common). A single CPU chip is difficult to directly complete ...[Details]
