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 K
EE
L
OQ
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.
Operating
4.0V – 6.0V operation
4 MHz external RC oscillator
Learning indication on LRNOUT
Auto baud rate detection
Power saving SLEEP mode
