Introduction

HCS365 is a hopping code encoder designed for secure RKE systems and secure remote control systems. The HCS365 utilizes KEELOQ hopping code technology, which combines high security, compact package form factor, and low cost, making this device an ideal solution for one-way authentication systems and access control systems.

The HCS365 creates a secure transmission code by combining a hopping code generated by a nonlinear encryption algorithm with a serial number and status bits. The length of the transmission code eliminates the threat of access techniques such as code scanning and code grabbing.

The encryption key, serial number, and configuration data are stored in an EEPROM array that cannot be accessed through any external connection. Data in the EEPROM is programmable but read-protected. Data can only be verified after an automatic erase-and-program operation. This prevents attempts to retrieve the encryption key or manipulate synchronization values. In addition, the HCS365 supports dual encoder functionality. This means two manufacturers can use the same device without requiring the same manufacturer code in each encoder. The HCS365 provides an easy-to-use serial interface for programming the necessary encryption keys, system parameters, and configuration data.
