I recently went to a friend's house to help him move. My friend gave me a few JM38510/12908BPA to play with. When I went home and checked the specification, I had no idea what gate circuit chip it was...
I have seen some designs add matching resistors of around 50 ohms at memory interfaces such as SRAM and SDRAM.It can be seen as reducing overshoot and sitting phenomenon, but there are also many desig...
I have visited many forums and read many posts, but never replied to any of them. However, eeworld is the first place that makes me want to reply. So I decided to settle down here. Here are two small ...

System design is a complex process. It is not enough to just use ICs. There are many details to consider. This article uses a high-fidelity music playback system as an example to introduce how to s...[Details]
Battery life is critical for portable applications. For applications such as smoke detectors, security devices, and thermostats, factory-installed batteries need to last for more than 10 years. The...[Details]
1 Introduction
Ultrasonic waves have strong directivity, slow energy consumption, and can propagate over long distances in a medium, so they are used for distance measurement. Ultrasonic detec...[Details]
Instrument stepper motor
The stepper motor is an open-loop control element that converts electrical pulse signals into angular displacement or linear displacement. In the case of non...[Details]
1. What is temperature?
Heat is a type of molecular motion. The hotter an object is, the faster its molecules move. Absolute zero is defined as the temperature at which all molecular motion ...[Details]
I've been studying dot matrix recently. It looks simple, but it takes a while to master it completely! The 8*8 dot matrix hardware circuit I'm making now is like this. The row is driven by 74HC138 + t...[Details]
