DESCRIPTION  
The HCS360 is a code hopping encoder designed for  
secure Remote Keyless Entry (RKE) systems. The  
HCS360 utilizes the KEELOQ code hopping technology,  
which incorporates high security, a small package  
outline and low cost, to make this device a perfect  
solution for unidirectional remote keyless entry systems  
and access control systems.  
Typical Applications  
The HCS360 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 HCS360 combines  
a 32-bit hopping code  
generated by a nonlinear encryption algorithm, with a  
28/32-bit serial number and 7/3 status bits to create a  
67-bit transmission stream. The length of the  
transmission eliminates the threat of code scanning  
and the code hopping mechanism makes each  
transmission unique, thus rendering code capture and  
resend (code grabbing) schemes useless.  
• Burglar alarm systems
