TDA8037
TDA8037 is Low power 3V smart card interface manufactured by NXP Semiconductors.
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 ponent 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 n F multilayer ceramic capacitors with low ESR
- Current spikes of 40 n A up to 20 MHz, with controlled rise and fall times, filtered overload detection approximately 120 m A
- 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 Electro Static Discharge (ESD) protection of (> 8 k V)
- 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 patible 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 CLKIN, f CLKIN/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)
