FEATURES

DESCRIPTION  
The Microchip Technology Inc. HCS512 is a code hop-  
ping decoder designed for secure Remote Keyless  
Entry (RKE) systems. The HCS512 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 keyless entry system.  
• Secure storage of Manufacturer’s Code  
• Secure storage of transmitter’s keys  
• Up to four transmitters can be learned  
• KEELOQ code hopping technology  
• Normal and secure learning mechanisms  
PACKAGE TYPE  
Operating  
PDIP, SOIC  
• 4.0V – 6.0V operation  
• 4 MHz external RC oscillator  
• Learning indication on LRNOUT  
• Auto baud rate detection  
• Power saving SLEEP mode

• 28-bit Serial Number  
The Manufacturer’s Code, transmitter keys, and syn-  
chronization information are stored in protected on-  
chip EEPROM. The HCS512 uses the DATA and CLK  
inputs to load the Manufacturer’s Code which cannot  
be read out of the device.  
• 16-bit Synchronization counter  
• Discrimination bits equal to Serial Number 8 LSbs  
• 66- to 69-bit length code word.
