TDA8035HN/C1/S1J

Specialized Overview

The TDA8035HN/C1/S1J is a high-integrated, low-power smart card interface IC manufactured by NXP Semiconductors. It operates with a VDDP supply voltage range of 2.7 V to 5.5 V and an interface supply (VDD(INTF)) of 1.6 V to 3.6 V. The device generates regulated card supply voltages of 5 V, 3 V, or 1.8 V using an internal DC-to-DC converter. Power consumption varies from 3 µA in deep shutdown mode to 220 mA in active mode at 5 V. It features thermal and short-circuit protection, enhanced ESD protection exceeding 8 kV, and supports clock frequencies up to 20 MHz. The component is housed in an HVQFN32 package.

Specialized Feature Summary

• Provides comprehensive protection for contact smart cards including thermal shutdown, short-circuit detection on all contacts, and enhanced electrostatic discharge resistance.
• Integrates a DC-to-DC converter capable of generating 5 V, 3 V, and 1.8 V card supplies from a single power domain with controlled activation sequences.
• Supports flexible clock generation up to 20 MHz via external crystal or input, with synchronous frequency division options.

Specialized Applications

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

Specialized Procurement Notes

Verify the specific ordering suffix against the manufacturer's datasheet to ensure correct packaging and compliance version. Confirm that the C1 variant meets the required ISO 7816 standards for the target application. Cross-reference the part number with official NXP documentation to validate availability and lifecycle status before finalizing procurement plans.

Specialized Selection Notes

Select this component for applications requiring a cost-efficient successor to the TDA8024 with software compatibility. Ensure the design accommodates the HVQFN32 package thermal requirements. Verify that the system controller can manage the specific activation and deactivation sequences defined in the functional description.

Specialized Part Context

The TDA8035HN/C1/S1J belongs to the TDA8035HN series of smart card interface ICs. It serves as a direct replacement for older models like the TDA8024 while offering improved power efficiency and integrated protection features. The C1 designation indicates a specific version compliant with standard ISO 7816 protocols.

Specialized Replacement Considerations

The TDA8035HN/C1 is software compatible with the TDA8024 and TDA8034. Designers should verify pinout compatibility and timing parameters when migrating from these legacy components to ensure seamless integration without hardware redesign.
