产品特点 Features

• Integrated circuit smart card interface
• 3 V, 1.8 V or 1.2 V smart card supply
• Low power consumption in inactive mode
• Three protected, half duplex, bidirectional buffered input/output lines (C4, C7 and C8)
• VCC regulation:
  • 3 V, 1.8 V or optionally 1.2 V at +- 5 pct using one 220 nF and one 470 nF low ESR multilayer ceramic capacitor.
  • Current pulse handling for pulses of 40 nAs at VCC = 3 V, 15 nAs at VCC = 1.8 V or VCC = 1.2 V up to 20 MHz
• Thermal and short-circuit protection for all card contacts
• Automatic activation and deactivation sequences triggered by short-circuit, card take-off, overheating, falling VDD(INTF) and VDD(INTREGD)
• Enhanced card-side ElectroStatic Discharge (ESD) protection of > 6 kV
• Clock signal using the internal oscillator or an external crystal (≤ 26 MHz) connected to pin XTAL1
• Card clock generation up to 20 MHz with synchronous frequency changes of fxtal, 1/2 fxtal, 1/4 fxtal or 1/8 fxtal using pins CLKDIV1 and CLKDIV2
• Non-inverted control of pin RST using pin RSTIN
• NDS certified
• Supply supervisors during power on and off:
  • VDD(INTREGD) using a fixed threshold
  • VDD(INTF) using resistor bridge threshold adjustment
• Built-in debouncing on card presence contacts (typically 4.5 ms)
• Multiplexed status signal using pin OFFN
