AN4409 Datasheet, PDF (1/8 Pages) STMicroelectronics – Using the same antenna for M24LRXXE-R and M24SRXX-Y Dual Interface EEPROM families

AN4409
Application note
Using the same antenna for M24LRXXE-R and M24SRXX-Y
Dual Interface EEPROM families
Introduction
The purpose of this document is to explain why the different tuning capacitance allows
customers to use the same 13.56 MHz antenna design for M24LRXXE-R ISO15693 and
M24SRXX-Y ISO14443 Dynamic NFC/RFID tag IC families. This document clarifies also the
reference value of the tuning capacitance for M24LRXXE-R and M24SRXX-Y antenna
design.
Table 1 lists the products concerned by this application note.
