TDA8035HN/C2/S1QL

Specialized Overview

The TDA8035HN/C2/S1QL is a high-integrated, low-power smart card interface IC manufactured by NXP Semiconductors. It serves as the cost-efficient successor to the TDA8024 and complies with ISO 7816, NDS, and EMV 4.3 standards. The device features a DC-to-DC converter generating 5 V, 3 V, or 1.8 V card supplies from a 2.7 V to 5.5 V input (VDDP). It includes thermal and short-circuit protection on all contacts, enhanced ESD protection exceeding 8 kV, and supply supervision. The IC operates in an HVQFN32 package with three protected half-duplex bidirectional buffered I/O lines.

Specialized Feature Summary

• Compliant with EMV 4.3 standard for secure payment systems
• Integrated DC-to-DC converter for flexible card voltage generation
• Automatic activation and deactivation sequences triggered by software or hardware faults

Specialized Applications

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

Specialized Procurement Notes

Verify the specific ordering suffix S1QL against official documentation to confirm packaging details. Ensure compatibility with the C2 version requirements for EMV 4.3 compliance. Cross-reference the part number with authorized distributors to confirm availability and authenticity before procurement.

Specialized Selection Notes

Select this component for applications requiring EMV 4.3 compliance and low power consumption. The C2 version specifically supports copper wiring standards. Ensure the host system can manage the Deep Shutdown mode to minimize standby current. Verify that the external capacitor values meet the ESR requirements for the DC-to-DC converter operation.

Specialized Part Context

This part belongs to the TDA8035HN series of smart card interface ICs. It is functionally similar to the TDA8034 but offers enhanced security features and lower power consumption. The C2 variant distinguishes itself through compliance with the EMV 4.3 standard, making it suitable for modern contactless and contact payment environments.

Specialized Replacement Considerations

The TDA8035HN/C1/S1J is a compatible alternative within the same family. Note that the C1 version does not support EMV 4.3 compliance. Ensure that any replacement maintains the HVQFN32 package footprint and pin configuration for direct integration.
