Low-power RF daily consumption? This has been mentioned by many manufacturers for many years, but the conceptual products that are still illusory today are finally going to go down the altar. “Think about it, you can control all the appliances in your home with a remote control, and you don't have to operate the appliance directly,†Chen Xiongji, marketing manager of Texas Instruments' low-power wireless products division in Asia, introduced the company's newly launched low. Looking forward to the power consumption RF product CC2530. The CC2530 supports the IEEE 802.15.4 standard and includes a wide range of applications including ZigBee PRO networks, ZigBee RF4CE remote control, smart energy, home and building automation, environmental monitoring, and wireless medical. "In addition to remote control, the CC2530 can also meet the needs of audio/video consumer electronics, advanced home automation, and personal wireless medical devices to build smart homes," Chen Xiongji added. According to Chen Xiongji, CC2530 is another 2.4GHz (2.4~2.483GHz) ISM Zigbee product after CC2340 and CC2341. There are three reasons for choosing to continue to introduce the crowded 2.4G frequency band: first, it is a global frequency band, and the developed products are globally versatile; secondly, its overall bandwidth is better than other ISM bands, which improves the overall data. The transmission rate allows the system to coexist; the third is the size, the 2.4 GHz radio and antenna can be the smallest size, and the product size can be smaller. And because of the protection of many mechanisms in the IEEE 802.15.4 standard, Zigbee has a stronger anti-interference advantage in the 2.4GHz band than Wi-Fi, Bluetooth, WirelessUSB and home cordless phones and microwave ovens. In the CC2530 preaching process, Chen Xiongji repeatedly pointed out to the non-net reporter that "we are not providing a pure hardware product, but a complete solution for the entire system." The so-called complete solution refers to the hardware, software and development tools that the product may use during the development process. “With years of market experience, in terms of development tools and software requirements, we always provide more customers with more than he needs. In addition, the easy upgrade between different products is also one of the competitive advantages of TI products.†He said . Compared with competing products, 256K memory capacity is also one of the characteristics of CC2530. Chen Xiongji said: "Like ZigBee smart energy today requires more powerful Flash storage, 256K CC2530 can meet more complex designs and applications." In the ZigBee, ZigBee PRO design process, how many nodes can the network specifically access? It is also one of the concerns of the majority of engineers. Chen Xiongji replied to the non-network reporter: "For us, it is to design different networks according to different customers. The following picture shows the ZigBee Demo of our US office. Through different hardware and protocol stacks, they can coexist. Network. There are probably more than 100 nodes in this network. Our goal is to install 400 nodes in this small office. So the customer has a concept: What can ZigBee do?" Whether it's 100 or 400, that's not to say that they are the limits of ZigBee's network development, it's just the numbers that our office can achieve," he added. Wireless is in the development stage, and many applications are not what we can imagine today. "Our biggest hope is to provide customers with a platform for customers to build wireless applications they can imagine on this platform," Chen Xiongji said with infinite expectation.
