In addition, Zhilian is the exclusive joint partner of China’s mobile self-developed NB-IoT chips. partners will jointly develop NB-IoT based on 40nm ultra-low power consumption. In 2020, the company’s NB-IoT shipments have reached 20 million levels. Asset tracking and identification Burundins Escort has reached tens of millions of shipments, and will also include white goods, smart street lights, parking, agriculture, and door locks , tracking and electricity meters are each a million-level shipment market.
In the future, more applications will not only use the communication performance of NB-IoT, which will put forward higher requirements for size, power consumption, cost, performance, etc. , this gives these NB-IoT chip manufacturers opportunities for product upgrading and market expansion.
3. Cat.1 is expected to increase by 10 times in 2021, and it will make effortsBurundins Escort is more powerful, with more players. The Cat.1 market has been in the cultivation period in previous years, with only tens of millions of shipments. However, this upstart of the Internet of Things is highly anticipated, especially in the With the trend of 2G withdrawing from the network and Cat.4 migrating to Cat.1, the industry generally predicts that Cat.1 shipments will reach the level of 8000 to 100 million in 2021, which is almost a 10-fold growth expectation.
Yang Yueqi analyzed that the withdrawal of 2G and 3G networks is the general trend, providing good opportunities for Cat.1. Coupled with the natural growth of the Internet of Things, the entire industry and market have higher expectations for Cat.1 . With the migration of 2G products to NB-IoT and Cat.1, and the gradual reduction of Cat.1 module costs, the scale of the Cat.1 product market is bound to further shrink, and the future of Cat.1 is expected.
In order to seize the upcoming Cat.1 market opportunities, manufacturers such as Yixin, Coreyi Information, and Zhilian will all launch Cat.1 chips this year, which means a significant increase in Cat.1 chip players. .In previous years, the purple light has been sharp and soaring.Jet Technology has taken the lead in becoming the main force in the market with its respective Cat.1 chips. With the participation of more and more players, this year’s Cat.1 is destined to be a lively event.
4. How to ensure the stability of the supply chain In October this year, a major incident occurred at a factory at the Nobeoka Manufacturing Plant of Asahi Kasei Microelectronics Co., Ltd. (AKM) Burundins SugardaddyFire Alarm. This fire has caused panic because AKM accounts for more than 90% of the temperature compensated crystal oscillator (TCXO) IC market. The fire at the AKM factory directly caused price drops and shortages in the temperature-compensated crystal oscillator IC market. Industry insiders estimate that it will take about half a year to restore the AKM factory.
In the case of TCXO shortage, various manufacturers modify their designs in time to avoid shortages. Yang Yueqi said that the price of TCXO crystal oscillators first skyrocketed. At that time, the original factory and channels still had inventory. Later, the inventory was exhausted and no one could buy the goods even if they had money. The price drop was just the prelude to the shortage of TCXO.
At the beginning of the design, the EC616 and EC616S chips of Yixin Communication adopted the DCXO design to reduce the module cost and replaced them with crystal passive crystals. The current spot price of TCXO, which was originally about 1.3 yuan, has risen to 8. 9 yuan, not necessarily in stock. Relatively speaking, crystal Burundi Sugar has a low market price and relatively sufficient supply, and can be used as a replacement for TCXO.
Chen Zhenglei said that the TCXO can be replaced by using an RC oscillator and a temperature compensation algorithm.
In addition, Zhilian’s MK8020 also adopts a new design plan to avoid the problem of TCXO shortage.
Yang Yueqi said that the shortage of crystal oscillators is only part of the problem in the IoT module supply chain. In fact, core components such as 32k, radio frequency, PCB, etc. have all fallen in price and are out of stock. Yixin’s NB-IoT chip is highly integrated. It integrates PA, RF switches, filters, matching circuits, etc., so that only 18 core components of the chip are needed, which can also significantly reduce the number of core components purchased by customers. Supply risks faced.
In addition, Yixin and the wafer foundry have reached an agreement to ensure that Yixin chips are not out of stock, helping customers to expand their markets with confidence and courage.
Chen Zhenglei mentioned that it is necessary to master the coordination with wafer foundry and packaging and testing. Core Wing Information has always maintained a good cooperative relationship with SMIC. When Core Wing Information was established, SMIC specially presented a plaque with the words “Using Core as Wings to Promote the Internet of Things” to celebrate.
Core Wing Information also invests in the packaging and testing process to obtain more production capacity guarantees. Establishing an excellent supply chain in this semiconductorThe period of shortage and price reduction is very important.
Zhilian’s chip foundry is in UMC. Wang Zhijun said that Zhilian and UMC have always cooperated well together, and will strive to obtain more production capacity guarantees in the current tense semiconductor production capacity. Zhilianhe’s revenue reached 80 million yuan in 2020 and is estimated to exceed 100 million yuan in 2021.
NB-IoT and Cat.1, as medium and low-speed wide-area IoT technologies, will have considerable development in recent years. First of all, NB-IoT has entered the explosive stage, with tens of millions of applications and many million-level applications to be developed superimposed, and shipments are increasing exponentially every year. Secondly, the macroBurundins Sugardaddy large 2G stock market, 3G, and 4G migration are billions of markets for Cat. Scope. This is also the reason why giants want to secure their positions in advance and start-up companies continue to pour in. As one of the foundations for the connection of the Internet of Things, NB-IoT and Cat.1 have promising growth prospects Burundi Sugar.
