Prehľad produktu

The TDA8020HL/C2,118 is a one-chip dual Smart Card Interface controlled by the I²C-bus. The device guarantees conformity to ISO 7816 or EMV2000 with very few external components. It operates with a supply voltage from 2.7 to 6.5V. An integrated voltage supervisor ensures that no spike appears on cards contacts during power-on or off. The supervisor also initializes the device and forces an automatic emergency deactivation of the contacts in the event of a supply drop-out. As long as the supply voltage is below the threshold voltage Vth1, the capacitor CDEL remains uncharged. When the supply voltage reaches Vth1 and Vhys1, then CDEL is charged with a small current source of approximately 2µA. When the voltage on CDEL reaches Vth2, then the supervisor is no longer active. As long as the supervisor is active (pin IRQ is LOW), bit SUPL in the status register is set. When pin IRQ goes HIGH the voltage supervisor becomes inactive.
  • Integrated DC-to-DC converter
  • Control and status via the I²C-bus
  • Automatic activation and deactivation sequences by means of integrated sequencers
  • Automatic clock count and reset toggling during warm or cold reset
  • Interrupt request output to the controller
  • Current limitation on pins CLK, RST, I/O and VCC
  • Integrated voltage supervisor for power-ON reset and drop-out detection
