[Domestic chip] Recommended: 69P21 from Sinowin Electronics

Recommendation: Zhongying Electronics' 69P21. Let me talk about a project I have done. It was a controller with a timer function for a brand. The timer part used Zhongying Electronics' 69P21. I had a very deep impression that I made about 200,000 pieces. After burning, I put on SMT patches and then ran the production test function. In total, only about 10 chips were found to be defective. Because the burning was encrypted, there was no way to determine whether it was a defective burning or a defective chip itself. The failure rate is very low.
