GENERAL DESCRIPTION

• Button inputs have internal pull-down resistors

• LED output

The HCS365 is a code hopping encoder designed for

secure Remote Keyless Entry (RKE) and secure

remote control systems. The HCS365 utilizes the

• PLL control for ASK and FSK

• Low external component count

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.

Typical Applications

The HCS365 is ideal for Remote Keyless Entry (RKE)

applications. These applications include:

The HCS365 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.

• Automotive RKE systems

• Automotive alarm systems

• Automotive immobilizers

• Gate and garage door openers

• Identity tokens

• Burglar alarm systems
