Typical Applications

The HCS300 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 HCS300 from Microchip Technology Inc. is a code

hopping encoder designed for secure Remote Keyless

Entry (RKE) systems. The HCS300 utilizes the KEELOQ

code hopping technology, incorporating high security, a

small package outline and low cost. The HCS300 is a

perfect solution for unidirectional remote keyless entry

systems and access control systems.

PACKAGE TYPES

HCS300 BLOCK DIAGRAM

The HCS300 combines a 32-bit hopping code,

generated by a nonlinear encryption algorithm, with a

28-bit serial number and 6 information bits to create a

66-bit code word. The code word length eliminates the

threat of code scanning and the code hopping mecha-

nism makes each transmission unique, thus rendering

code capture and resend schemes useless.
