DESCRIPTION

The Microchip Technology Inc. HCS512 is a code hop-

ping decoder designed for secure Remote Keyless

Entry (RKE) systems. The HCS512 utilizes the pat-

ented KEELOQ 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 Code, transmitter keys, and syn-

chronization information are stored in protected on-chip

EEPROM. The HCS512 uses the DATA and CLK inputs

to load the Manufacturer’s Code which cannot be read

out of the device.

The HCS512 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.
