Guide to migrating from CLRC663 to derivates

The main objective of this document is to explain the steps for migrating from CLRC663 to MFRC631, MFRC630 or SLRC610. This document will give a short overview about the changes in soft and hardware

Protocol related communication to MIFARE cards is not scope of this document.

From a hardware point of view nothing has to be changed. The MFRC631, MFRC630 and SLRC610 are fully pin compatible to CLRC663. The antenna matching also doesn't need to be changed. But be aware tuning and measurement of the reader antenna has always to be performed at the final mounting position to consider all parasitic effects, e.g. metal influence on quality factor, inductance and additional capacitance.
