Add Microchip MCS3142 Keeloq enocder #1885

Closed swbr closed 6 years ago

swbr commented 6 years ago

The Microchip MCS3142 is used in many car key fobs to detect pressed buttons, encode an encrypted data package, and send it via e.g. 433MHz. Two crystals, the buttons and a battery are the only necessary external components for this TSSOP20 IC. See http://ww1.microchip.com/downloads/en/DeviceDoc/40001747A.pdf

The device has pins DATA_IN/OUT and CONTROL_IN/OUT, which are not described in the datasheet, except that the OUTs should be connected to the INs. So, I have grouped those four pins together on the left for a more clear schematic.
