DESCRIPTION
The HCS300 from Microchip Technology Inc. is a code
hopping encoder designed for secure Remote Keyless
Entry (RKE) systems. The HCS300 utilizes the K
EE
L
OQ
code hopping technology, incorporating high security, a
small package outline and low cost. The HCS300 is a
perfect solution for unidirectional remote keyless entry
systems and access control systems.

Typical Applications
The HCS300 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 HCS300 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.
