The HCS300-I/SN from Microchip Technology is a secure code hopping encoder utilizing KEELOQ® technology. It is designed for unidirectional remote keyless entry and access control systems, offering high security with a small package outline and low cost.
Key features include a programmable 28-bit serial number, a programmable 64-bit encryption key, and a 66-bit transmission code length. The 32-bit hopping code ensures each transmission is unique, preventing code scanning and capture. The device operates from 2.0V to 6.3V and includes four button inputs, with internal pull-down resistors. It also offers selectable baud rates and an automatic code word completion feature.
This encoder is ideal for applications such as automotive RKE systems, alarm systems, immobilizers, gate and garage door openers, and identity tokens. The HCS300-I/SN is housed in an 8-SOIC package and supports surface mount installation.
The integrated EEPROM stores crypt keys, serial numbers, and configuration data, which are read-protected to prevent unauthorized access. An easy-to-use serial interface is provided for programming necessary keys and system parameters. The device also includes an on-chip oscillator and timing components, reducing external circuitry requirements.
