TDA8037T/C1Y

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 V regulation: CC 3V 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, V , VREG and V DDhost DD 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 f , f /2 (with SO28 package only) CLKIN CLKIN 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)TDA8037 NXP Semiconductors Low power 3V smart card interface 2.2.1 Other TSSOP16 and SO28 package SO28 version is footprint compatible with TDA8024T Compliant with ISO 7816, Cisco technology and EMV 4.3 payment systems 3.
