TDA8037T/C1S

Specialized Overview

The TDA8037T/C1S is a low-power smart card interface IC designed for contact readers operating in the 3 V supply domain. It provides comprehensive protection including thermal and short-circuit safeguards, enhanced ESD protection exceeding 8 kV, and supply supervision. The device supports ISO 7816, Cisco technology, and EMV 4.3 standards. It features three protected half-duplex bidirectional buffered I/O lines (C4, C7, C8), an external clock input up to 20 MHz, and a built-in debouncing feature on the card presence contact. Software compatibility extends to the TDA8024, TDA8034, and TDA8035 series.

Specialized Feature Summary

• Integrated thermal and short-circuit protection on all card contacts
• Enhanced electrostatic discharge (ESD) protection exceeding 8 kV
• Built-in debouncing on the card presence contact
• Software compatible with TDA8024, TDA8034, and TDA8035

Specialized Applications

• Pay TV systems
• Electronic payment terminals
• Identification devices
• Banking IC card readers

Specialized Procurement Notes

Verify the specific ordering suffix 'S' against official NXP documentation to confirm package type and tape-and-reel specifications. Ensure the component meets RoHS compliance requirements for your target market. Cross-reference the datasheet revision date to confirm availability of updated application notes and design resources.

Specialized Selection Notes

Select this component for applications requiring strict power efficiency within a 3 V supply domain. The SO28 package offers footprint compatibility with the legacy TDA8024T, facilitating direct upgrades. Verify that the system controller can support the required activation sequences and fault detection logic via the CMDVCCN and OFFN pins.

Specialized Part Context

The TDA8037 serves as a cost-efficient successor to the established TDA8035 integrated contact smart card reader IC. It maintains high security levels while optimizing current consumption during shutdown mode. This positioning makes it suitable for power-sensitive designs where robust card protection and protocol compliance are critical.

Specialized Replacement Considerations

The TDA8037 is software compatible with the TDA8024, TDA8034, and TDA8035. Designers upgrading from these models should verify pin configurations, particularly noting that the SO28 version is footprint compatible with the TDA8024T.
