As the most important wireless connection technology in IoT applications - "Bluetooth, WiFi, ZigBee, Sub-G" are all supernatural. Shiqiang, which has been continuously developing in the field of Internet of Things, has focused on Zigbee and SUB-G technologies, which are derived from the complete, powerful, reliable and easiest-to-use wireless solution of Shiqiang's Silicon Labs. Silicon Labs has the most comprehensive SUB-GHz wireless interconnect products, including EZRadio, EZRadioPRO, and Wireless MCU. Its core advantages include: transmit power up to 20dbm, accept sensitivity up to -126dbm, and sleep current as low as 50nA. Meter reading, electronic tags, wireless smoke, RKE, etc. Silicon Labs Ember ZigBee integrates cortex-M3 MCU, sleep current as low as 0.4uA, the industry's best protocol stack, free networking, etc., making it a smart home, smart energy monitoring, LED control (ZLL) ... the best choice for you. The most comprehensive SUB-GHz wireless interconnect solution to seize huge business opportunities In wireless applications, the wireless market below 1 GHz (Sub-GHz) has huge and growing business opportunities. Take the automobile and consumer electronics markets as an example: only the car's keyless entry system has 150 million sets of product market per year; and the market capacity of consumer electronics products is hundreds of millions of sets per year. In addition, home automation and automatic meter reading applications also have high market demand. Silicon Labs has the most comprehensive set of SUB-GHz wireless interconnects to meet these growing IoT applications, and these products are available in a wide range of product models, as shown in Figure 1. Figure 1. Silicon Labs SUB-GHz wireless products are available in a wide range of product models. EZRadioPRO includes all the attractive features of EZRadio RF transmitters, receivers and transceivers (eg high integration, low cost, flexibility, low BOM and easy design) while targeting more complex ISM band applications, and Several enhancement parameters and features are available, including frequency coverage from 119 to 1050 MHz and output power up to +20 dBm. It also includes built-in features such as wake-up timer, low-power detector, transmit and receive data FIFOs, power-on reset circuitry, and general-purpose digital I/O. The Wireless MCU integrates an 8-bit low-power MCU, coupled with the high-end wireless performance of EZRadioPRO, is a SOC wireless MCU product that not only has the best wireless features, but also has its own unique 8051 MCU features. 1. EZRadio - simple design, lower BOM cost application The EZRadio series is designed to be simple and suitable for lower BOM cost applications. The Si4010 RF Transmitter is the industry's first single-chip remote control IC that requires a single external bypass capacitor, a printed circuit board, battery, and a housing with buttons to form a complete wireless remote control. The Si4010 features a patented crystalless oscillator architecture with carrier frequency accuracy of ±150 ppm over the commercial temperature range and ±250 ppm over the industrial temperature range. It is more accurate than traditional surface acoustic waves (SAW). The transmitter is twice as high and does not require an external crystal oscillator. Figure 2. The Si4010 transmit solution requires only one capacitor externally. As shown in Figure 2 above, the Si4010 launch solution requires only one capacitor external to the competitor solution. 2. EZRadioPRO - superior performance and cost over competitive products The performance of all aspects of the EZRadioPRO series has been improved compared to EZRadio, with an excellent price/performance ratio. As shown in Figure 3 below, the transmit power can reach 20dBm compared to competing products (compared to competitive devices typically only reach 13 dBm). EZRadioPRO achieves -126 dBm compared to the competitor's sensitivity of -115 dBm. The full frequency range can reach 115-1050MHz, and can pass the full frequency test, and the competitive products are generally fixed frequency points. Figure 3. The advantages of EZRadioPRO over competing products. EZRadioPRO has lower system cost, and competitive products need to add PA/LNA to achieve the same performance as EZRadioPRO, so the overall cost is greatly saved. In addition, lower operating current (18mA at +10dBm, ~85mA at +20dBm), 50nA sleep current, and reduced MCU load are all advantages of EZRadioPRO. Especially worth mentioning is the Si4438, which is tailor-made for China's smart meters. It is the most energy-efficient sub-GHz wireless solution in the smart meter market in China. It provides sleep/standby current (50nA, register content retention) compared to similar transceivers. The device is 40 times lower. Utilizing an efficient on-chip power amplifier (PA), the Si4438 IC extends transmission distance and provides a reliable communication link for smart meters by providing +20dBm output power, -124dBm sensitivity, 114dB link budget, and 58dB adjacent channel rejection. . At the same time, the built-in diversity antenna and frequency hopping support can further extend the transmission distance and enhance wireless performance. Because the diversity antenna is tightly integrated into the Si4438 transceiver, it can increase the system link budget by 8~10dB, which can effectively extend the transmission distance even under harsh environmental conditions. 3. Lowest Power Wireless MCU - Integrated 240-960MHZ Wireless Transceiver The Si10xx Wireless MCU family is the industry's lowest power single-chip solution, combining an MCU solution with a Sub-GHz integrated RF transceiver. These products are designed to meet the specific requirements of low power embedded systems that require RF bidirectional communication links. Key features include: l Longer battery life (the industry's lowest sleep power consumption of 100nA) l Support single battery power supply l Industry leading link budget (146 dB) l No need for external PA transmit power up to +20 dBm The acceptance sensitivity of l -126 dBm greatly improves the acceptance range l Unique DC-DC boost conversion can reduce battery consumption l 5x6mm QFN-36 small package is ideal for space-constrained IoT applications l 2uS wake-up time l Support antenna diversity Figure 4.
