HCS512 Datasheet
http://www.microchip.com/stellent/images/mchpsiteimages/dwnfolder.gifHCS512 DatasheetThe HSC512 is a code hopping decoder designed for secure Remote Keyless Entry (RKE) systems. The HCS512 utilizes the patented KEELOQ® code-hopping system and high security learning mechanisms to make this a canned solution when used with the HCS encoders to implement unidirectional remote keyless entry systems. The manufacturer’s code, transmitter keys, and synchronization information are stored in protected on-chip EEPROM. 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. Sophisticated error checking algorithms are built in to ensure only valid codes are accepted. Typical applications include automotive remote entry systems, automotive alarm systems, automotive immobilizers, gate and garage openers, electronic door locks, identity tokens and burglar alarms. HCS512 is available in 18-pin DIP/SOIC packages.
