Typical Applications

The HCS200 is ideal for Remote Keyless Entry (RKE)

applications. These applications include:

The HCS200 combines

a 32-bit hopping code

• Fixed code replacement

• Automotive RKE systems

• Automotive alarm systems

• Automotive immobilizers

• Gate and garage door openers

• Identity tokens

generated by a non-linear encryption algorithm, with a

28-bit serial number and 6 information 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 schemes useless.

• Burglar alarm systems

DESCRIPTION

The encryption key, serial number, and conﬁguration

data are stored in EEPROM which is not accessible via

any external connection. This makes the HCS200 a

very secure unit. The HCS200 provides an easy to use

serial interface for programming the necessary security

keys, system parameters, and conﬁguration data.

The HCS200, from MicrochipTechnology Inc., is a code

hopping encoder designed for Remote Keyless Entry

(RKE) systems.The HCS200 utilizes the Keeloq code

hopping technology, which incorporates high security, a

small package outline and low cost, to make this device

a perfect solution for replacement of ﬁxed code devices

in unidirectional remote keyless entry systems and

access control systems.

All encryption 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.
