The HCS370 is a code hopping encoder designed for  
secure Remote Keyless Entry (RKE) and secure  
remote control systems. The HCS370 utilizes the  
®
KEELOQ code hopping technology, which incorpo-  
Typical Applications  
rates high security, a small package outline, and low  
cost to make this device a perfect solution for unidirec-  
tional authentication systems and access control sys-  
tems.  
The HCS370 is ideal for Remote Keyless Entry (RKE)  
applications. These applications include:  
• Automotive RKE systems  
• Automotive alarm systems  
• Automotive immobilizers  
• Gate and garage door openers  
• Identity tokens  
The HCS370 combines a hopping code generated by a  
nonlinear encryption algorithm, a serial number, and  
status bits to create a secure transmission code. The  
length of the transmission eliminates the threat of code  
scanning and code grabbing access techniques.  
• Burglar alarm systems
