Nanjing qinheng micro

http://www.wch.cn

Nanjing qinheng Microelectronics Co., Ltd. is an integrated circuit design company , Founded on 2004 year , The company is located in Nanjing, Jiangsu ;

Rely on its advantages in interface and simulation , It introduces integration USB, Ethernet , Touching BLE SoC; Here's the picture ;

Read its official information , The product has several major features

• Support 5V Power supply and 3.3V Power supply , compatible 5V I//O And 3.3V IO;

• built-in USB2.0 And TouchKey peripherals

• Since the research RISC-V kernel

   

• The product information is very comprehensive

Different from general process chips , Information of qinheng's products , Supporting development board , development tool , Aspects are very comprehensive ;

And the electrical parameters in the data book are very detailed , for instance , For power consumption , The situation is as follows ：

Of course , Its products also have some unreasonable places , For example, it matches RAM resources ,512KB Flash Configuration of , Provided only 18KB Of SRAM;

This resource and the mainstream in the market 64KB Of SRAM There is still a big difference ; Do many applications , Will be constrained ;

Lingsi microelectronics

Ling Siwei was not established for a long time ,2019 Founded in , At present, there is no official website available ;

See the product information for the first time , The most characteristic is [email protected] Sensitivity ; This should be regarded as the top in the industry ;

Remove sensitivity , The power consumption characteristics of its products are also first-class in China , It is a high-performance Bluetooth data transmission core ;

In a highly competitive market ,LE501x The performance index of still makes engineers' eyes shine ;

Telink

As the leader of low-power Bluetooth in China , The previous product line of tailing micro is basically based on private 32 position RISC nucleus , Developers roast a lot about the difficulty of software development ;

On the other hand , Tailing micro product line has been full BLE, Classic Bluetooth is missing ;

TLSR951x Release , It perfectly complements the product line of tailing ;

TLSR951x be based on RISC-V processor , classic bluetooth & bluetooth 5.2 Bimodal , The highest dominant frequency 96MHz, To configure 256KB SRAM  +  Maximum 2MB Flash; It is worth mentioning that , Chip support 5V Power supply , as well as 125°C High temperature of ;

TLSR951x series , Focus on headphones , High end wearable , High end human-computer interaction ;

Ambiq

Ambiq Of MCU With its lowest power consumption in the industry ;

2019 year ,Ambiq The release is based on CEVA IP Low power Bluetooth chip ; The biggest feature still depends on it SPOT Patented technology (Subthreshold Power Optimized Technology), That is, low power consumption ;

In addition to power consumption ,Appollo 3 Blue One is also provided Stepper Motor Controller; 

be based on Appolo 3 Blue Low power consumption characteristics of , as well as 96MHz High dominant frequency ,FPU, Its main push is voice detection 、 Wearable applications ;

Appollo 3 Blue On the other hand is High complex design and high cost ; The following figure shows the circuit design , Especially the power supply and RF Matching part ;

InPlay, Qun Wei

https://www.inplay-tech.cn

Inplay It is a representative of a typical Bluetooth chip company with integrated software and hardware design ;

For asset management , Launched by real-time positioning NanoBeacon,IN100 chip ; adopt OTP Burn relevant configuration information , Power on the chip and operate according to the beacon ;

IN100 Support 1.1V~3.6V Battery powered ,DFN8(2.5mm*2.0mm) Ultra small package of ;

Launched for low delay wireless networking IN618, Main application game peripherals , Low delay wireless audio , Industrial robot , Smart classroom ;

IN618 Provides 96KB The big SRAM, And audio processing engine ;
