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 sys-  
tems 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.  
• Burglar alarm systems
