KEELOQ Code Hopping Decoder

FEATURES

Security

DESCRIPTION

The Microchip Technology Inc. HCS500 is a code hop-

ping decoder designed for secure Remote Keyless

Entry (RKE) systems. The HCS500 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 and access control systems. The

HCS500 can be used as a stand-alone decoder or in

conjunction with a microcontroller.

• Encrypted storage of manufacturer’s code

• Encrypted storage of crypt keys

• Up to seven transmitters can be learned

• KEELOQ code hopping technology

• Normal and Secure learning mechanisms

OSCILLATOR

Compatible Encoders

All KEELOQ encoders and transponders configured for

the following setting:

The manufacturer’s code, crypt keys, and synchroniza-

tion information are stored in encrypted form in external

EEPROM. The HCS500 uses the S_DAT and S_CLK

inputs to communicate with a host controller device.

• PWM modulation format (1/3-2/3)

• TE in the range from 100us to 400us

• 10 x TE Header

The HCS500 operates over a wide voltage range of

3.0 volts to 5.5 volts. The decoder employs automatic

bit-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.

• 28-bit Serial Number

• 16-bit Synchronization counter

• Discrimination bits equal to Serial Number 8 LSbs

• 66- to 69-bit length code word.
