TDA8002CG/C1,518

Specialized Overview

The TDA8002CG/C1,518 is an IC card interface manufactured by NXP Semiconductors. It operates within a supply voltage range of 3.0 to 6.5 V and supports ambient temperatures from -25 °C to +85 °C. The device provides a regulated card supply output of 4.6 to 5.4 V for 5 V environments or 2.76 to 3.24 V for 3 V environments. It features three protected half-duplex bidirectional buffered I/O lines with a maximum frequency of approximately 200 kHz. Clock generation for the card reaches up to 12 MHz using internal oscillators or external strobe inputs. The component is housed in a 32-lead LQFP package (SOT401-1) and includes thermal protection, short-circuit protection, and a low-power sleep mode.

Specialized Feature Summary

• Supports synchronous and asynchronous smart cards compliant with ISO 7816, GSM 11.11, and EMV specifications.
• Integrates a step-up converter for card supply generation and a supply supervisor for spike elimination.
• Includes chip select functionality to enable parallel operation of multiple devices.

Specialized Applications

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

Specialized Procurement Notes

Verify the specific ordering suffix /C1,518 against manufacturer documentation to confirm exact packaging and marking details. Confirm that the LQFP32 package variant matches the design requirements. Check current availability status as older series components may have limited stock or end-of-life implications.

Specialized Selection Notes

Select this component when designing contact-based smart card readers requiring single-supply operation between 3.3 V and 5 V. Ensure the application utilizes the LQFP32 package format. Verify that the required clock frequencies and I/O line counts align with the device's capabilities for both synchronous and asynchronous protocols.

Specialized Part Context

The TDA8002C belongs to the TDA80xx series of contact smart card reader ICs from NXP Semiconductors. This series is designed for easy integration into set-top boxes, mobile devices, and standalone readers. The CG variant specifically denotes the plastic low profile quad flat package configuration within this product family.

Specialized Replacement Considerations

Consult official NXP documentation for direct pin-compatible substitutes within the TDA80xx series. Verify functional equivalence regarding voltage levels and protocol support before replacing.
