TDA8035HN: High integrated and low power smart card interface

Protection of the contact smart card

• Thermal and short-circuit protection on all card contacts
• V_CC regulation:
  • 5 V, 3 V, 1.8 V ± 5 % on 2 × 220 nF multilayer ceramic capacitors with low ESR
  • current spikes of 40 nA/s (V_CC = 5 V and 3 V) or 15 nA/s (V_CC = 1.8 V) up to 20 MHz, with controlled rise and fall times, filtered overload detection is approximately 120 mA
• Automatic activation and deactivation sequences initiated by software or by hardware in the event of a short-circuit, card take-off, overheating, falling V_REG V_DD(INTF),V_DDP
• Enhanced card-side ElectroStatic Discharge (ESD) protection of (> 8 kV)
• Supply supervisor for killing spikes during power on and off:
  • threshold internally fixed
  • externally by a resistor bridge

Easy integration into your contact reader

• SW compatible to TDA8024 and TDA8034
• 5 V, 3 V, 1.8 V smart card supply
• DC-to-DC converter for V_CC generation separately powered from 2.7 V to 5.5 V supply (V_DDP and GNDP)
• Very low power consumption in Deep Shutdown mode
• Three protected half-duplex bidirectional buffered I/O lines (C4, C7 and C8)
• External clock input up to 26 MHz
• Card clock generation up to 20 MHz using pins CLKDIV1 and CLKDIV2 with synchronous frequency changes of f_XTAL, f_XTAL/2, f_XTAL/4, f_XTAL/8
• Non-inverted control of pin RST using pin RSTIN
• Built-in debouncing on card presence contact
• Multiplexed status signal using pin OFFN
• Chip Select digital input for parallel operation of several TDA8035 ICs.
