FEATURES

DESCRIPTION  
The HCS201 from Microchip Technology Inc. is a code  
hopping encoder designed for secure Remote Keyless  
Entry (RKE) systems. The HCS201 utilizes the KEELOQ  
code hopping technology, incorporating high security, a  
small package outline and low cost. The HCS201 is a  
perfect solution for unidirectional remote keyless entry  
systems and access control systems.  
• Programmable 28-bit serial number  
• Programmable 64-bit encryption key  
• Each transmission is unique  
• 66-bit transmission code length  
• 32-bit hopping code  
• 34-bit fixed code (28-bit serial number,  
4-bit button code, 2-bit status)

• The HCS201 is ideal for Remote Keyless Entry  
(RKE) applications. These applications include:  
V
DD  
• Automotive RKE systems  
• Automotive alarm systems  
• Automotive immobilizers  
• Gate and garage door openers  
• Identity tokens  
The HCS201 combines a 32-bit hopping code,  
generated by a nonlinear encryption algorithm, with a  
28-bit serial number and 6 information bits to create a  
66-bit code word. The code word length eliminates the  
threat of code scanning and the code hopping mecha-  
nism makes each transmission unique, thus rendering  
code capture and resend schemes useless.
