Recently, I have been paying attention to some chips (mostly domestic) [Copy link]

 

A few days ago, I wrote two articles (Hangshun + Shengbangwei) in the theme event of the most powerful domestic chips. Later, I added another article, which I mentioned later under the Hangshun post, and it is also my recent

I only learned about the cheapest domestically produced Bluetooth chip among Bluetooth SOCs from a younger brother: Lenze.

But later I went back and found that I had not received any rejection.

Of course, regarding Shengbangwei’s chip, it seems that the administrator MM talked to me for a while, and then said that she would discuss it again when she got back, but there was no follow-up.

So, I didn’t continue writing.

However, later on, starting from Hangshun, a post was made and my name was specifically mentioned, which was a great honor.

Of course, I am more regretful that I actually hope that the first wave of mentions is Shengbangwei's power chip, because as I said, it is really the first domestic chip I feel is widely used, although it is just an ordinary

Power chip.

As for Hangshun, hi, although this model is indeed very affordable and full of sincerity, after all, it was not released too early. Moreover, although it is also a rare "tssop20+1 almost 2 cents", the problem is that it is not the only one~

As I was writing, I thought about the fact that I have been paying attention to several chips recently - mainly MCU, of course, especially BLE MCU.

So, I suddenly thought about writing a post and chatting about it.

This also includes the DA14531 wristband kit that I rushed to produce with PCB+SMT in the early stage——

The embarrassing thing about it is that when I first paid attention to this chip, I was thinking of a smart ring - that is, I just wanted it to be small.

I just wanted it to be cheap... But to be honest, at that time, I didn't consider the scenario of using a display screen, especially a color screen.

So later, when I thought of the form of the bracelet kit, in fact, everything else is easy to say, but once the GUI is used, the MCU is obviously

Not quite enough.

So, I started paying attention to some other chips.

Unify, let’s just chat briefly in this post

Of course, I can mention one thing first - its main feature is that it is cheap, and it is best if it is domestically produced.

Also, don’t be disdainful of small clients.

Because, in an era when domestic substitution is just the right time and everyone is competing with each other, to be honest, domestic chips are plentiful, cheap, and in great demand.

However, there are usually only one or two companies that do not look down on small customers.

For wild developers, it is better to have good data performance, unless you want to make it into a product.

I remember someone said that Hangshun does not produce chips, but only does OEM.

Does it mean package die?

It seems so, but his is indeed cheap.

The more famous domestic power chip manufacturers include Huawei HiSilicon, Unisoc, Senmu Leishi, Mojie, etc.

Among them, Huawei HiSilicon and Unisoc have outstanding performance in the field of communication equipment, and Mojie has a high position in the field of power management chips. In particular, it is an innovative code-free digital power control chip that can achieve code-free rapid development of high-power power supplies. Each chip has its own advantages and characteristics, and the specific decision should be based on demand and budget.

What model?

A few days ago, I finally got the job done and will start work on April 1st.

Because moving from Foshan to Shenzhen is another troublesome process. Moving is not life-threatening, but packing up is.

Then, because I had more time, I quietly cleaned up and read the book "Daisy and Declutter".

(Speaking of "Datsu-shō-ri", I actually read a book and found out that this is the experience of an old Japanese woman who has been practicing it for eight or nine years. So even though I feel uncomfortable with many of the things she said, after all, it is a summary of more than 8 years of experience, and it is effective, so I just hold my nose and bear it.)

After cleaning up, I suddenly realized that my electronic tools, components, boards, etc. were too many and too messy.

Similar~~

My "MCU" folder is as high as 99.9G!

It was nearly 100G, which scared me, so I started to clean it up.

Then discovered some chips I had long forgotten about.

BlueX micro

Ah, yes, it may be called BXMicro for short

This is a domestic BLE SOC chip factory that seems to be not very well-known so far.

I know him because a few years ago, my friend said that he was going to cooperate with an agent to develop a solution with a color screen based on this high-configuration, low-cost BLE SOC, bla bla bla

Then, I found that this chip also has some good features that I expect:

1. SDK and datasheet are available

Of course, I didn’t find a direct channel to buy this chip - mainly because it’s not available on LiChuang, Taobao, or the first few Baidu lists, and I didn’t go out of my way to look for it.

But then I thought, this folder can be deleted.

After all, the information is easy to get, right?

And it's been a few years, and its SDK is not updated very quickly.

But at least there will be updates on gitee in 2023.

Yes, I checked it out, lvgl is still in there~~

It just seems to be more mature now and is put in the demo.

So I really don’t need to keep all those things I had, of course I have to keep my own pictures and stuff.

This one is not Bluetooth, it is just a regular 32-bit one. Yes, it was one of the many alternatives to STM8S003 back then.

CX32L030, actually this model was introduced to me by a forum friend, and the price is also 1.2 yuan, which is similar to the Hangshun one.

It’s just that it’s not available for sale on LiChuang.

I just searched on Baidu and found out which company it belongs to.

But now, after knowing Puran, I......

I was chatting with his agent on Taobao the other day, and he said bluntly -

The purpose is to kill these people.

Yes, other people have already made it to 40 or 50 cents or 70 or 80 cents, so let’s just say whether it’s worth it or not.

Damn, what's wrong? Why are there several old screenshots?
