TDA8002CT/C/C1,518

Specialized Overview

The TDA8002CT/C/C1,518 is a low-power analog interface for asynchronous and synchronous IC cards, manufactured by NXP Semiconductors. It operates on a single supply voltage of 3.0 to 6.5 V and provides regulated card supply voltages of 5 V ±5% or 3 V ±5%. The device features three protected half-duplex bidirectional buffered I/O lines and generates clock signals up to 12 MHz internally or accepts external clocks up to 20 MHz. It supports ISO 7816, GSM 11.11, and EMV specifications with integrated step-up converters, supply supervisors, and thermal protection.

Specialized Feature Summary

• Integrated power management including step-up converter and supply supervisor for stable operation
• Supports both synchronous and asynchronous smart card protocols with flexible clock generation
• Includes chip select input for parallel configuration of multiple units

Specialized Applications

• GSM applications
• Banking systems
• Electronic payment terminals
• Identification readers
• Pay TV interfaces

Specialized Procurement Notes

Verify the specific ordering suffix against the manufacturer's current product specification to confirm package type and environmental compliance status. Ensure the component matches the required pinout variant (CT/C) for the intended PCB layout. Cross-reference the datasheet revision date to confirm functional parameters remain unchanged from historical documentation.

Specialized Selection Notes

Select this component when designing interfaces requiring ISO 7816 compatibility with low-power constraints. Verify that the system voltage falls within the 3.0 to 6.5 V range. Consider the SOP28 package dimensions if space is limited. Ensure the microcontroller can handle the required activation and deactivation sequences via CMDVCC and MODE pins.

Specialized Part Context

This part belongs to the TDA8002 family of IC card interfaces produced by Philips/NXP Semiconductors. It serves as an intermediary between the smart card and the host microcontroller, handling all supply, protection, and control functions. The CT/C variant specifically utilizes a plastic small outline package with 28 leads.

Specialized Replacement Considerations

TDA8004AT and TDA8004T are documented similar parts in the same family. Verify pin compatibility and feature set differences before substitution.
