DESCRIPTION
The HCS361 is a code hopping encoder designed for
secure Remote Keyless Entry (RKE) systems. The
HCS361 utilizes the K
EE
L
OQ
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.
The HCS361 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. The length of the
transmission eliminates the threat of code scanning
and the code hopping mechanism makes each
transmission unique, thus rendering code capture and
resend (code grabbing) schemes useless.
Typical Applications
The HCS361 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
