DESCRIPTION

The Microchip Technology Inc. HCS515 is a code hop-

ping decoder designed for secure Remote Keyless

Entry (RKE) systems. The HCS515 utilizes the pat-

ented code hopping system and high security learning

mechanisms to make this a canned solution when used

with the HCS encoders to implement a unidirectional

remote and access control systems. The HCS515 can

be used as a stand-alone decoder or in conjunction

with a microcontroller.

PACKAGE TYPE

BLOCK DIAGRAM

The manufacturer’s code, encoder decryption keys,

and synchronization information are stored in

encrypted form in internal EEPROM. The HCS515

uses the S_DAT and S_CLK inputs to communicate

with a host controller device.

The HCS515 operates over a wide voltage range of

4.5V – 5.5V. The decoder employs automatic bit rate

detection, which allows it to compensate for wide vari-
