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

DESCRIPTION

The HCS361 is a code hopping encoder designed for

secure Remote Keyless Entry (RKE) systems. The

HCS361 utilizes the KEELOQ® code hopping technol-

ogy, which incorporates high security, a small package

outline and low cost, to make this device a perfect

solution for unidirectional remote keyless entry sys-

tems and access control systems.

DESCRIPTION

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.
