HCS201

KEELOQ Code Hopping Encoder

FEATURES

Security

DESCRIPTION

The HCS201 from Microchip Technology Inc. is a code

hopping encoder designed for secure Remote Keyless

Entry (RKE) systems. The HCS201 utilizes the

KEELOQ^®code hopping technology, incorporating high

security, a small package outline and low cost. The

HCS201 is a perfect solution for unidirectional remote

keyless entry systems and access control systems.

• Programmable 28-bit serial number

• Programmable 64-bit encryption key

• Each transmission is unique

• 66-bit transmission code length

• 32-bit hopping code

• 34-bit fixed code (28-bit serial number,

4-bit button code, 2-bit status)

PACKAGE TYPES

• Encryption keys are read protected

PDIP, SOIC

Typical Applications

VDD

• The HCS201 is ideal for Remote Keyless Entry

(RKE) applications. These applications include:

1 0

• Automotive RKE systems

• Automotive alarm systems

• Automotive immobilizers

• Gate and garage door openers

• Identity tokens

The HCS201 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.

• Burglar alarm systems
