FEATURES  
Security  
DESCRIPTION  
The HCS301 from Microchip Technology Inc. is a code  
hopping encoder designed for secure Remote Keyless  
Entry (RKE) systems. The HCS301 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.  
• 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)  
PACKAGE TYPES  
PDIP, SOIC  
• Encryption keys are read protected

Typical Applications  
The HCS301 is ideal for Remote Keyless Entry (RKE)  
applications. These applications include:  
S2  
S3  
S1 S0  
• Automotive RKE systems  
• Automotive alarm systems  
• Automotive immobilizers  
• Gate and garage door openers  
• Identity tokens  
The HCS301 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.
