HCS515  
KEELOQ® Code Hopping Decoder  
FEATURES  
Security  
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  
hopping technology  
• Normal and secure learning mechanisms

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_DATand 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-
