DESCRIPTION
The HCS301 from Microchip Technology Inc. is a code
hopping encoder designed for secure Remote Keyless
Entry (RKE) systems. The HCS301 utilizes the
K

OQ®
code hopping technology, which incorpo-
rates high security, a small package outline and low
cost, to make this device a perfect solution for unidirec-
tional remote keyless entry systems and access control
systems.

Typical Applications
The HCS301 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
Burglar alarm systems

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.
