一.产品概述mWi嘉泰姆

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

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

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

are required  mWi嘉泰姆

二.产品特点mWi嘉泰姆

◆IC card interface  mWi嘉泰姆

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

◆Three specifically protected half-duplex bidirectional buffered I/O mWi嘉泰姆

  lines to card contacts C4, C7 and C8  mWi嘉泰姆

◆DC/DC converter for VCC generation separately powered from a 5 V ± 20% supply mWi嘉泰姆

 (VDDP and PGND) mWi嘉泰姆

◆3 or 5 V ± 5% regulated card supply voltage (VCC) with appropriate decoupling has the  following capabilities:mWi嘉泰姆

 - ICC < 80 mA at VDDP = 4 to 6.5 V mWi嘉泰姆

 - Handles current spikes of 40 nAs up to 20 MHz mWi嘉泰姆

 - Controls rise and fall times mWi嘉泰姆

 - Filtered overload detection at approximately 120 mA  mWi嘉泰姆

◆Thermal and short-circuit protection on all card contacts  mWi嘉泰姆

◆Automatic activation and deactivation sequences; initiated by software or by mWi嘉泰姆

 hardware in the  event of a short-circuit, card take-off, overheating, VDD mWi嘉泰姆

 or VDDP drop-out  mWi嘉泰姆

◆Enhanced ESD protection on card side (>6 kV)  mWi嘉泰姆

◆26 MHz integrated crystal oscillator  mWi嘉泰姆

◆Clock generation for cards up to 20 MHz (divided by 1, 2, 4 or 8 through CLKDIV1 and CLKDIV2 signals) with synchronous frequency changes  mWi嘉泰姆

◆Non-inverted control of RST via pin RSTIN  mWi嘉泰姆

◆ISO 7816, GSM11.11 and EMV (payment systems) compatibility  mWi嘉泰姆

◆Supply supervisor for spike-killing during power-on and power-off and Power-on reset (threshold fixed internally or externally by a resistor bridge)  mWi嘉泰姆

◆Built-in debounce on card presence contacts  mWi嘉泰姆

◆One multiplexed status signal OFF  mWi嘉泰姆

◆Package:SOP28mWi嘉泰姆
