The HCS370T/ST from Microchip Technology is a state-of-the-art secure remote keyless entry (RKE) system designed to provide an unparalleled level of security and convenience for automotive and remote control applications. This advanced system is built around a KEELOQ® hopping code encryption algorithm, which ensures that every transmission between the key fob and the receiver is unique, thereby preventing code grabbing and unauthorized access.

Robust Security Features

The HCS370T/ST is equipped with a range of security features that safeguard against various forms of attacks. The KEELOQ technology is a proven encryption method that uses a hopping code to prevent replay attacks. Additionally, the system includes a 32-bit serial number and a 28-bit function code with a 66-bit encryption key, providing a high level of cryptographic security.

Flexible and User-Friendly Design

This RKE system is designed for flexibility, offering manufacturers the ability to program and configure the device to meet specific application requirements. It supports up to 15 different function codes, allowing for a wide range of control options within a single system. The user-friendly design ensures that end-users can easily operate their devices with minimal effort.

Low Power Consumption

Efficiency is at the heart of the HCS370T/ST design. The system is optimized for low power consumption, making it ideal for battery-operated devices where power management is crucial. This feature extends the battery life of the key fob, reducing the need for frequent replacements and maintenance.

Wide Range of Applications

While primarily used in automotive RKE systems, the versatility of the HCS370T/ST makes it suitable for a variety of other applications, including garage door openers, home security systems, and other remote-controlled devices. Its robust security and easy-to-use interface make it an excellent choice for any application requiring secure and reliable wireless communication.
