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.

PACKAGE TYPES

HCS201 BLOCK DIAGRAM

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.
