† NOTICE:  Stresses above those listed under "Absolute Maximum Ratings" may cause permanent damage to the device.  This is a stress rating only and functional operation of the device at those or any other conditions above hose indicated in the operation listings of this specification is not implied.  Exposure to maximum rating conditions for extended periods may affect device reliability.


Description

The Microchip Technology Inc. HCS512 is a code hop- ing decoder designed for secure Remote Keyless ntry (RKE) systems. The HCS512 utilizes the pat-ented KEELOQ code hopping system and high security earning mechanisms to make this a canned solution hen used with the HCS encoders to implement a uni-directional remote keyless entry system.

The Manufacturer's Code, transmitter keys, and syn-chronization information are stored in protected on-chip EPROM. 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.
