NCN8024DWR2G

Specialized Overview

The NCN8024DWR2G is a single smart card interface IC designed for 3.0 V and 5.0 V reader/writer applications, compatible with ISO 7816-3, EMV, and NDS standards. It features three bidirectional buffered I/O level shifters (C4, C7, C8) and an internal DC/DC converter providing a regulated card power supply up to 75 mA at 3.3 V or 5.5 V. The controller interface operates on an independent supply range of 2.7 V to 5.5 V. It supports clock frequencies up to 18 MHz via internal division ratios of 1/1, 1/2, 1/4, and 1/8. The device includes thermal and short-circuit protection, ESD protection up to 8 kV HBM, and an interrupt signal for card presence and faults. It is available in SOIC-28 and TSSOP-28 packages.

Specialized Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to ensure package type and compliance status match requirements. Confirm moisture sensitivity level and reflow soldering profile compatibility with assembly processes. Check for any product change notifications regarding pinout or electrical characteristics updates before finalizing procurement specifications.

Specialized Selection Notes

Select this component when a dedicated single-chip solution for ISO 7816-3 compliant smart card interfaces is required. Ensure the system controller voltage falls within the 2.7 V to 5.5 V range for VDD. Verify that the application requires support for both 3 V and 5 V smart cards and can accommodate the recommended external capacitor values for the DC/DC converter and charge pump circuits.
