TDA8034HN Low power smart card interface Rev. 3.5 13 March 2020 Product data sheet 1. General 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. 2. Features and benefits Integrated circuit smart card interface in an HVQFN24 package 5V, 3V or 1.8V smart card supply Very low power consumption in Deep Shutdown mode Three protected half-duplex bidirectional buffered I/O lines (C4, C7 and C8) V regulation: CC 5V, 3V or 1.8V 5 % using two low ESR multilayer ceramic capacitors: one of 220 nF and one of 470 nF current spikes of 40 nA/s (V = 5 V and 3 V) or 15 nA/s (V =1.8 V) up to CC CC 20 MHz, with controlled rise and fall times and filtered overload detection of approximately 120 mA Thermal and short-circuit protection for all card contacts Automatic activation and deactivation sequences triggered by a short-circuit, card take-off, overheating, falling V , V or V DD DD(INTF) DDP Enhanced card-side ElectroStatic Discharge (ESD) protection of > 8 kV External clock input up to 26 MHz connected to pin XTAL1 Card clock generation up to 20 MHz using pins CLKDIV1 and CLKDIV2 with 1 1 1 synchronous frequency changes of f , f f or f xtal 2 xtal, 4 xtal 8 xtal Non-inverted control of pin RST using pin RSTIN 1 Compatible with ISO 7816, NDS and EMVCo4.3 payment systems Supply supervisor for killing spikes during power on and off: using a fixed threshold using an external resistor bridge with threshold adjustment Built-in debouncing on card presence contacts (typically 8 ms) Multiplexed status signal using pin OFFN 1.
