It is a new generation of single-chip wireless/receiving chip launched by a French company, which is mainly used in the field of wireless radio frequency remote control. Higher sensitivity than previous generation products. In the application environment, the sensitivity can be achieved, greatly increasing the receiving distance. At the same time, it has a higher level of integration, and all high-frequency signal receiving functions are integrated on-chip to achieve the most reliable receiving effect with the fewest peripheral components and the lowest cost. Therefore, it is a single-chip receiving device that inputs high-frequency signals to the antenna and outputs digital signals in the true sense. At the same time, all processing and tuning are automatically completed on-chip, thus eliminating the manual adjustment process during development and production, which naturally reduces costs and enhances the competitiveness of the product.
In order to make the product have a longer standby time, it has two unique functions
Off mode. Used to stop operation and the system enters a low power consumption state.
Wake-up function. After receiving a signal input, the chip will send a wake-up signal to the main controller to wake it up and notify it of the exit status. These functions are more conducive to users designing low-power or ultra-low-power products, such as
