TDA8037 Low power 3V smart card interface Rev. 1.2 — 30 June 2016 Product data sheet 1. General description The TDA8037 is the cost efficient successor of the established integrated contact smart card reader IC TDA8035. It offers a high level of security for the card performing current limitation, short circuit detection, ESD protection as well as supply supervision. Operating in 3 V supply domain, the current consumption during the shutdown mode of the contact reader is very low. It is therefore the ideal component for a power efficient contact reader. 2. Features and benefits 2.1 Protection of the contact smart card  Thermal and short-circuit protection on all card contacts  VCC regulation:  3 V  5 % on 2  220 nF multilayer ceramic capacitors with low ESR  Current spikes of 40 nA up to 20 MHz, with controlled rise and fall times, filtered overload detection 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, VDDhost, VREG and VDD dropping  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 (with SO28 package only) 2.2 Easy integration into your contact reader          SW compatible to TDA8024, TDA8034 and TDA8035 3 V smart card supply Three protected half-duplex bidirectional buffered I/O lines (C4, C7 and C8) External clock input up to 20 MHz Card clock generation up to 20 MHz using pin CLKDIV with synchronous frequency changes of fCLKIN, fCLKIN/2 (with SO28 package only) 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 TDA8037 ICs (with SO28 package only) PDF
