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.  
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.  
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.
