DESCRIPTION
The Microchip Technology Inc. HCS509 is a code hop-
ping decoder designed for secure Remote Keyless
Entry (RKE) systems. The HCS509 utilizes the pat-
ented K
EE
L
OQ
code hopping system and high security
learning mechanisms to make this a canned solution
when used with the HCS encoders to implement a uni-
directional remote keyless entry system.
PACKAGE TYPE
BLOCK DIAGRAM
The manufacturer’s key, transmitter keys, and synchro-
nization information are stored in protected on-chip
EEPROM. The HCS509 uses the DAT and CLK inputs
to load the manufacturer’s key and cannot be read out
of the device.
The HCS509 operates over a wide voltage range of
3.0 volts to 6.0 volts. The decoder employs automatic
baud rate detection which allows it to compensate for
wide variations in transmitter data rate. The decoder
contains sophisticated error checking algorithms to
ensure only valid codes are accepted.
