Domestic Chip List: Xin Xin recommends the newly discovered 1.8 yuan Bluetooth chip, Lenze ST17H66, what do you think? [Copy link]

 

EEWorld's initial draft of the "Best Competitive Domestic Chip List", I wonder if you have browsed it? If not, please click here to browse it . If you comment before March 28, you will have a chance to win a gift (a total of 10 gifts, gift details ).

Today I would like to share with you a newly discovered 1.8 yuan Bluetooth chip recommended by expert Xin Xin. What do you think about it? Welcome to post a comment to discuss.

Recommender: @辛昕

Recommended product model: ST17H66
Manufacturer: Lenze

Recommended reasons:

Of course, I just learned about this chip and haven't had time to verify it yet. However, what I'm interested in is that the price is as low as 1.8 yuan! It's even packaged in tssop20 . Friends, friends! Do you remember anything? STM8S003F6P6, friends. Yes, yes, yes, it also provides an STM32-style development board !

There are two major pain points for Bluetooth chips: 1. The most painful is that if you are not a corporate customer with an order volume, there is no SDK, no sample purchase channel, and even the datasheet is not shown to you. I really don’t know when such a common market as MCU will become as strict as cellular and network card chips. 2. The price is not low. Today’s domestic MCUs, no matter which market, do not seem to care about or are willing to do low-price markets, and they all go the route of increasing quantity without increasing prices. For example, Hengxuan and Ambiq have even put on 2D GPUs, but the price just won’t come down. Who can you talk to? You say I just want to make an ordinary little thing, brother, I don’t need a screen, what do you do with a GPU for me? (Including the price-performance ratio, it is so bad that I will basically be asked if I can do it in an interview now. Jerry) Therefore, the price of Bluetooth SoC, in my opinion, is from the 1-dollar series of foreign brands to the half-dollar series. Anyway, it still costs three or four yuan, which is not a low price. However - I have been looking for low-priced Bluetooth chips in the past, but at that time, I rarely found one that could reach this price range. Finally, I have found it now - in fact, it was my good friend Xianzai who told me about it first - Lenze's 66 series, the price is only 1.8 yuan, 8 yuan. And it also has the magical tssop20 package. The key is that it is also an ARM CM0 core! However, as a domestic Bluetooth SoC, it has an advantage - regardless of the company, the order volume, or whether it is business-to-business, 1.8 yuan is the Taobao price. Don't ask 1KU, don't ask 100 pieces... Oh, sorry, it's 1.8 yuan for more than 50 pieces. But... less than 5 pieces is only 2.5 yuan! The most important thing is - you can get the SDK and read the datasheet at will, although the original manufacturer may not guarantee to serve you well - but it's already 1.8 yuan, what else do you want?

The most difficult part about Bluetooth is compatibility and technical support. If compatibility is not good and technical support is not up to par, I won’t dare to use it no matter how cheap it is. I don’t know how this company does in these two aspects.

I have a project that uses Bluetooth recently. Is there any way to contact the manufacturer to provide a demo board for testing?

There is a new Xiangyuan in Nanjing, which is difficult to use

But the price is really cheap

I don't know if it's the low price that attracts customers, but it would be pretty good if it remained this price.

This SOP16 SH1766B, which is the 1.8 model, is an ARM core, but I just found a very bad thing about it.

It does not bring out the SWD interface, that is, there is no SWDIO and SWCLK.

The serial port is used to download the program, and simulation is not supported.

It’s very regrettable, it feels like we have returned to the 51 era.

Of course, this also saves more IO ports.

However, in the long term, this is an unsettling place.

I will continue to look at SH1765, it is a bit more expensive, after all, it is only about 3 yuan.

Still much cheaper than others.

And it is QFN32, and the resources are also rich.

I hope that friends who have used it can share some experience and performance parameters, which can provide reference information for everyone.

I have seen netizens say that Lentz's main feature is its cheapness, and its advantage is its cheapness. Other aspects are quite ordinary, but I haven't heard of any major problems. If it can be cheap without any big pitfalls, many people will like it.

The price of Bluetooth SoC, as far as I know, has dropped from the 1 dollar series of foreign brands to the half dollar series, which is still three or four dollars, which is not low. However, I have been looking for low-priced Bluetooth chips in the past, but I rarely found them in this price range.
