Typical Applications

The HCS300 is ideal for Remote Keyless Entry (RKE)

applications. These applications include:

The HCS300 combines

a 32-bit hopping code

generated by a non-linear encryption algorithm, with a

28-bit serial number and six status bits to create a

66-bit transmission stream. The length of the

transmission eliminates the threat of code scanning

and the code hopping mechanism makes each

transmission unique, thus rendering code capture and

resend (code grabbing) schemes useless.

• Automotive RKE systems

• Automotive alarm systems

• Automotive immobilizers

• Gate and garage door openers

• Identity tokens

• Burglar alarm systems

The encryption key, serial number, and conﬁguration

data are stored in EEPROM which is not accessible via

any external connection. This makes the HCS300 a

very secure unit. The HCS300 provides an easy to use

serial interface for programming the necessary security

keys, system parameters, and conﬁguration data.

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, which incorporates high secu-

rity, a small package outline and low cost, to make this

device a perfect solution for unidirectional remote key-

less entry systems and access control systems.

The encyrption keys and code combinations are pro-

grammable but read-protected. The keys can only be

veriﬁed after an automatic erase and programming

operation. This protects against attempts to gain

access to keys and manipulate synchronization values.

KeeLoq is a trademark of Microchip Technology Inc.

*Code hopping encoder patents allowed and pending.
