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.
