DESCRIPTION

The HCS361 is a code hopping encoder designed for

secure Remote Keyless Entry (RKE) systems. The

HCS361 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.

Typical Applications

The HCS361 is ideal for Remote Keyless Entry (RKE)

applications. These applications include:

The HCS361 combines

a 32-bit hopping code

• Automotive RKE systems

• Automotive alarm systems

• Automotive immobilizers

• Gate and garage door openers

• Identity tokens

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.

• Burglar alarm systems
