FEATURES

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.

• Encrypted storage of manufacturer’s code

• Encrypted storage of encoder decryption keys

• Up to seven transmitters can be learned code

All encoders and transponders configured for the fol-

lowing setting:

OSCILLATOR

• PWM modulation format (1/3-2/3)

• TE in the range from 100 µs to 400 µs

• 10 x TE Header

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_CLKinputs to communicate

with a host controller device.

• 28-bit Serial Number

• 16-bit Synchronization counter

• Discrimination bits equal to Serial Number 8 LSbs

• 66- to 69-bit length code word.

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-
