Application of HCS301 encoder in radio transmission circuit

Relevant key device information applied in this article: HCS301 AT93C4B QLK138 HCS301 rolling code encoding chip is a coding chip developed based on nonlinear flowing code algorithm. It includes 66-bit transmission code, 32-bit rolling code, and 64-bit programmable encryption. Key bit, 32-bit source code, can generate 266 combinations, ensuring that the password will not be repeated within 18 years. Its unique algorithm allows the rolling code decoder to not respond to the same password twice within the effective period of use, and each time it is sent The password is random, so it is impossible to decipher it. The application of HCS301 encoder in the radio transmission circuit is shown in the figure.
