Domestic alternatives to stm8s003f3p6 [Copy link]

 

The industry has not been very prosperous in the past two years, and everyone is trying to save money and cut costs. Coupled with the US ban on the sale of chips to Huawei, this thing we have always worried about but always thought would never happen has finally happened.

Although Huawei is barely holding on for now, there will be a second time after the first one, and no one knows when these things will develop into a complete sales ban.

At the same time, domestic products have also developed in recent years and are becoming more and more competitive, from peripherals to general-purpose MCUs.

As early as a few years ago, the STM8S003F3P6 chip successfully hit the domestic MCUs, including STC, which were under the banner of cheapness and patriotism.

The first thing that came to my mind was the 20-pin cheap microcontroller.

However, I later heard from a colleague that the price of STM8S003F3P6 had increased, and the supply was cut off. At that time, I listened to him and used a domestic MCU called CX32L003.

I didn’t think much about it at the time, and later on it almost caused a big mess. Luckily there are no major problems now.

At this time, I began to look for a variety of domestic MCUs that could replace this material.

Just a quick search.

Found the following models, waiting to be screened and tested

Nuvoton N76E003AT20 1.33 should be 32-bit, more expensive
MS51FB9AE
Xinsheng HC89S003F4 is similar to
Saiyuan Jinrui CA51F351P4
Lingdong MM32F003 series
Zhongji Guowei SM51F003
Taixin STK6037 Huada
HC32F003
a certain Taiwan series MS84F2004
Saiyuan SC92F8003X20U about 1 yuan, suitable for
HK8S003
Apte APT32F003F6P6 1.5 tax included, too expensive

The official price of STM8S003F3P6 10KU is $0.22 to $0.23, which is about RMB 1.4. This is the same price as a 74-piece model I bought a few years ago.

I consulted the agent today and he said it was the same price.

The prices of domestic alternatives are usually locked at around 1 yuan - this is the general price, not the price negotiated with agents for large quantities.

The idea is actually very simple:

The price should be kept within 1 yuan, and I don't have the stm8s003f3p6 product on hand, so if it is not pin2pin, but the functions are the same, I can accept it.

Of course, you must test it to make sure there is no problem - because when I used CX32L003, I used the tape-out when the chip was first released, and the library and data were also early,

Even according to the FAE found yesterday, this information may be considered tampered...

Therefore, once you decide to try to test one of the products, you should still find the original manufacturer or a better agent to get the official information and make sure that at least it is not

The chip just taped out.

STC's 8 series has TSSOP20, but the pins are not compatible. But there are also customized models: GS8S003
Shanghai AiSi Semiconductor: E85F003

I just saw someone else mentioned these three as alternatives, so I added them here.

Great, Xin Xin is really awesome! ! ! !

STC seems to have pin to pin compatibility, so you need to contact their customer service.

Now is the spring of domestic substitution, and ST prices have increased by dozens of times. However, domestic products have also been swept away by everyone.

N9001 can also be used as a replacement. Welcome to add friends to discuss. Some are in stock and were previously customized for large customers.

The author is indeed far-sighted and has a thorough analysis. I have learned a lot!
