The HCS370 is a code hopping encoder designed for

secure Remote Keyless Entry (RKE) and secure

remote control systems. The HCS370 utilizes the

KEELOQ 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 authentication systems and access control sys-

tems.

The HCS370 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

The HCS370 combines a hopping code generated by a

nonlinear encryption algorithm, a serial number, and

status bits to create a secure transmission code. The

length of the transmission eliminates the threat of code

scanning and code grabbing access techniques.

• Burglar alarm systems
