GENERAL DESCRIPTION

The HCS370 is a code hopping encoder designed for

secure Remote Keyless Entry (RKE) and secure

remote control systems. The HCS370 utilizes the

K

EE

L

OQ 廬

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 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.

Typical Applications

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

Burglar alarm systems
