　 HCS200 DESCRIPTION

　　The HCS200, from Microchip Technology 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.

　　The HCS200 combines a 32-bit hopping code 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.
