MFRC531中文资料飞利浦数据手册PDF规格书

INTRODUCTION

Scope

The MF RC531 is member of a new family of highly integrated reader ICs for contactless communication at 13.56 MHz. This reader IC family utilises an outstanding modulation and demodulation concept completely integrated for all kinds of passive contactless communication methods and protocols at 13.56 MHz. The MF RC531 is pin- compatible to the MF RC500, the MF RC530 and the SL RC400.
