The HCS301-I/SN is a high-performance code hopping encoder designed and manufactured by Microchip Technology Inc., specifically for secure Remote Keyless Entry (RKE) systems. This device utilizes Microchip's patented KEELOQ® hopping technology, which combines high security, a small package outline, and low cost, making it an ideal solution for unidirectional remote keyless entry systems and access control systems. The HCS301-I/SN generates a 32-bit hopping code using a non-linear encryption algorithm, along with a 28-bit serial number and six status bits, creating a 66-bit transmission stream. This length of transmission eliminates the threat of code scanning, and the code hopping mechanism makes each transmission unique, rendering code capture and re-send schemes useless. The encryption key, serial number, and configuration data are stored in EEPROM, which is not accessible via any external connection, enhancing the security of the HCS301-I/SN. It operates in a voltage range of 3.5V to 13.0V and is available in an 8-pin SOIC package .
