TDA8029HL/C206,118

Specialized Overview

The TDA8029HL/C206,118 is a low-power single-chip smart card reader featuring an embedded 80C51 core with 16 kB ROM, 256 byte RAM, and 512 byte XRAM. It includes a specific ISO7816 UART supporting T=0 and T=1 protocols, a 24-bit ETU counter, and programmable VCC generation (1.8 V to 5 V). The device supports card clock frequencies up to 20 MHz and operates on a supply voltage range of 2.7 V to 6.0 V. It provides enhanced ESD protection on card contacts and multiple power reduction modes for portable applications.

Specialized Feature Summary

• Integrated 80C51 microcontroller with dedicated memory and specialized ISO7816 UART for automatic protocol handling.
• Programmable DC-to-DC converter generating controlled VCC levels with current limitations on card contacts.
• Hardware sequencer managing automatic activation and deactivation sequences for smart cards.
• Support for asynchronous T=0 and T=1 protocols with character-level error management and parity counters.

Specialized Applications

• Portable card readers
• General purpose card readers
• EMV compliant card readers

Specialized Procurement Notes

Verify the complete part number including the suffix /C206,118 against official NXP documentation to confirm package type and embedded software version. Ensure compatibility with required EMVCo standards, noting that newer revisions may recommend alternative components for specific compliance requirements.

Specialized Selection Notes

Select this component for applications requiring a robust, low-power smart card interface with integrated microcontroller capabilities. Consider the available GPIOs and serial communication options when designing the host interface. Verify that the embedded software library meets the specific protocol requirements of the target smart cards.

Specialized Part Context

The TDA8029 series serves as a complete solution for smart card reading, integrating power management, clock generation, and protocol processing into a single LQFP32 package. It is designed to replace discrete component solutions in portable devices, reducing board space and simplifying design through its versatile hardware features and standard serial interface control.

Specialized Replacement Considerations

For EMVCo 4.3c support, the PN7412AU is recommended as the TDA8029 is no longer compliant with this specific standard. Check for updated application notes regarding software integration if migrating from older variants within the TDA8029 family.
