一.产品概述BMZ嘉泰姆

   The CXRS3108 is a complete and cost-efficient analog interface for asynchronousBMZ嘉泰姆

3 or 5 V smart cards. It can be placed between the card and the microcontroller to BMZ嘉泰姆

perform all supply, protection and control functions. Very few external components BMZ嘉泰姆

are required  BMZ嘉泰姆

二.产品特点BMZ嘉泰姆

◆IC card interface  BMZ嘉泰姆

◆3 or 5 V supply for the IC (VDD and GND)  BMZ嘉泰姆
