TDA8034HN Overview
Description
The TDA8034HN is a cost-effective analog interface for asynchronous and synchronous smart cards operating at 5 V, 3 V or 1.8 V. Using few external components, the TDA8034HN provides all supply, protection and control functions between a smart card and the microcontroller.
Key Features
- Integrated circuit smart card interface in an HVQFN24 package
- 5 V, 3 V or 1.8 V smart card supply
- Very low power consumption in Deep Shutdown mode
- Three protected half-duplex bidirectional buffered I/O lines (C4, C7 and C8)
- Thermal and short-circuit protection for all card contacts
- Automatic activation and deactivation sequences triggered by a short-circuit, card take-off, overheating, falling VDD, VDD(INTF) or VDDP
- Enhanced card-side ElectroStatic Discharge (ESD) protection of > 8 kV
- External clock input up to 26 MHz connected to pin XTAL1
- Non-inverted control of pin RST using pin RSTIN
- Compatible with ISO 7816, NDS and EMVCo4.3 1 payment systems
