KEELOQ Code Hopping Decoder

FEATURES

Security

DESCRIPTION

The Microchip Technology Inc. HCS500 is a code

hopping decoder designed for secure Remote Keyless

Entry (RKE) systems. The HCS500 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 a unidirectional 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

Compatible Encoders

All KEELOQ encoders and transponders configured for

the following setting:

The manufacturer’s code, crypt keys, and

synchronization 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 100 us to 400 us

• 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.
