The HCS301T-I/SN from Microchip Technology is a secure code hopping encoder utilizing KEELOQ technology for Remote Keyless Entry (RKE) applications. This device generates a 66-bit code word, combining a 32-bit hopping code with a 28-bit serial number and 6 information bits, making each transmission unique and resistant to code scanning.
Key security features include a programmable 64-bit encryption key and a programmable 28-bit serial number, with encryption keys protected from external access. The encoder operates over a wide voltage range of 3.5V to 13.0V and offers 15 functions with four button inputs. It includes an on-chip EEPROM for storing configuration data and synchronization information.
Designed for ease of use, the HCS301T-I/SN features an easy-to-use programming interface and requires minimal external circuitry. It is supplied in a standard 8-SOIC surface mount package, suitable for various automotive RKE systems, alarm systems, immobilizers, and access control applications.
