Wuhan Xinyuan Semiconductor continues to delve into the field of the Internet of Things, and after launching the Bluetooth series chip CW32R030, it has once again launched the Sub-1G series product CW32W031. This product is based on the SIP chip of CW32L031 and PAN3028, using 7.5mm × 7.5mm × 0.75mm ultra small QFN64 package with integrated wireless transceiver. The highly integrated design greatly reduces other external components, thereby reducing the overall BOM cost. The CW32W031 series of products not only simplifies the development process and accelerates product launch, but also provides higher security and flexibility.

CW32W031 adopts ChirpIoT^TM modulation and demodulation technology, supports half duplex wireless communication, and operates in the frequency bands of 370-590 MHz and 740-1180 MHz. It has high anti-interference, high sensitivity, low power consumption, and ultra long-distance communication characteristics. The highest sensitivity of -140dBm and output power of 22dBm make it the best choice for long-distance transmission and applications with high reliability requirements.

ChirpIoT^TM  introduction

ChirpIoT ™ is a wireless communication modulation and demodulation technology based on linear spread spectrum signals (Chirp signals). By improving the signal in both the time and frequency domains, it has the following main advantages compared to conventional modulation techniques:

There are significant advantages in blocking and neighboring channel selection, which can further improve communication reliability.

Greater flexibility allows users to adjust the spread spectrum modulation bandwidth, spread spectrum factor, and error correction rate, effectively improving the trade-off between distance, anti-interference ability, and power consumption of chips using conventional modulation techniques.

CW32W031 also has a Cortex-M0+core built-in, with a maximum main frequency of 48MHz, FLASH capacity of 64KB, and SRAM capacity of 8KB; The peripheral devices mainly include functional modules such as 1 channel 12 bit ADC, 3 channels UART, 1 channel IIC, 1 channel SPI, and multiple timers. Very suitable for narrowband IoT product applications, such as wireless automatic meter reading, long-distance data communication, smart home, industrial IoT, smart agriculture, supply chain logistics, etc.
