TDA8035HN/C1,157

TDA8035HN/C1,157 is a high-integrated and low power smart card interface. It is the cost efficient successor of the established integrated contact smart card reader IC TDA8024. It offers a high level of security for the card by performing current limitations, short-circuit detection, ESD protection as well as supply supervision. The current consumption during the standby mode of the contact reader is very low as it operates in the 3V supply domain. The TDA8035 is, therefore, the ideal component for a power-efficient contact reader. The application includes pay TV, electronic payment, identification, and IC card readers for banking.

• Thermal and short-circuit protection on all card contacts
• Enhanced card-side ElectroStatic Discharge (ESD) protection of (<gt/> 8kV)
• Supply supervisor for killing spikes during power on and off
• DC-to-DC converter for VCC generation separately powered from 2.7 to 5.5V supply (VDDP and GNDP)
• Very low power consumption in deep shutdown mode, multiplexed status signal using pin OFFN
• Three protected half-duplex bidirectional buffered I/O lines (C4, C7 and C8)
• Non-inverted control of pin RST using pin RSTIN, built-in debouncing on card presence contact
• Chip Select digital input for parallel operation of several TDA8035 Ics
• Power supply voltage range from 2.7 to 5.5V (Tamb = 25°C)
• HVQFN32 package, ambient temperature range from -25°C to +85°C
