DESCRIPTION

The HCS360 is a code hopping encoder designed for

secure Remote Keyless Entry (RKE) systems. The

HCS360 utilizes the K

which incorporates high security, a small package

outline and low cost, to make this device a perfect

solution for unidirectional remote keyless entry sys-

tems and access control systems.

The HCS360 combines a 32-bit hopping code

generated by a nonlinear encryption algorithm, with a

28/32-bit serial number and 7/3 status bits to create a

67-bit transmission stream.
