What is the difference between the Si4432 module and the Si4463 module

In the past few years, the Si4432 module of the wall-through king has been deeply loved by customers. However, since the birth of the Si4463 wireless radio frequency IC of Silicon, it has gradually replaced the Si4432 widely used by customers. Below, Si4432 and Si4463 are adopted by NiceRF Wireless. Take the wireless module of the chip as an example. Let’s take a look at the difference between the wireless modules of these two different ICs. To make it easier for everyone to read and save time, a comparison chart has been made so that everyone can see the difference at a glance. 

The receiving current of the Si4463 module is 10.7 mA, the receiving sensitivity is -126dbm, the transmission power can be adjusted to 128, the second generation of Ezradio_pro, the highest rate is 1Mbps, the measured distance is 2 kilometers, and it can be used in narrow bands, with better frequency selectivity and resistance. The interference is better, four GPIOs, and the price is more expensive.

The receiving current of the Si4432 module is 18 mA, the receiving sensitivity is -121dbm, the transmission power can be adjusted to 8, the first generation of Ezradio_pro, the highest rate is 256bps, the measured distance is 1.4 kilometers, it can not be used for narrowband, the frequency selectivity is normal, and the anti-interference General sex, three GPIO, cheap price.

The receiving sensitivity and the maximum output power basically determine the transmission distance of the si4432 and si4463 wireless modules, which is the wall penetration capability that users are most concerned about. Of course, the channel range is the wider the coverage, the better, because if the module is to be exported to other countries, some countries The frequency points used may be relatively rare, so the channel range transmission speed is of course the faster the better for the transmission of large amounts of data.

From the above comparison chart, we can see that the improvement of Si4463 compared to Si4432 is more significant. It can be said that Si4463 is an upgraded version of Si4432. The price of Si4432 and Si4463 wireless modules on the market is similar, and the price of the Si4463 wireless modules is slightly more expensive. In the case of similar prices, choosing Si4463 is undoubtedly correct.

Through the above analysis, I believe that everyone has a deeper understanding of the Si4432 and Si4463 wireless modules, and also understands the difference between the two. Finally, introduce the RF4463PRO module of Shenzhen NiceRF Wireless Technology Co., Ltd. This module is a 100mW wireless transceiver module made of the Silicon Lab Si4463C version of the device. It is in the range of receiving current, receiving sensitivity, transmitting power, and receiving speed. , Anti-interference ability, communication distance, etc. have been greatly improved.
