TDA8029HL/C207,118

Specialized Overview

The TDA8029HL/C207,118 is a low-power single smart card reader integrated circuit manufactured by NXP Semiconductors. It features an embedded 80C51 core with 16 kB ROM, 256 bytes RAM, and 512 bytes XRAM. The device supports ISO 7816 asynchronous protocols T=0 and T=1, including EMVCo4.3 compliance. It provides programmable VCC generation (1.8 V to 5 V) with controlled slew rates and card clock frequencies up to 20 MHz. Key electrical parameters include a supply voltage range of 2.7 V to 6.0 V, shutdown current under 20 μA, and enhanced ESD protection on card contacts exceeding 6 kV.

Specialized Feature Summary

• Integrated 80C51 microcontroller with dedicated hardware for ISO 7816 protocol handling
• Programmable DC-to-DC converter supporting multiple card supply voltages
• Hardware sequencer for automatic activation and deactivation sequences
• Low power modes including shut-down, sleep, and power-down states

Specialized Applications

• Portable card readers
• General purpose smart card readers
• EMV compliant payment terminals

Specialized Procurement Notes

Verify the specific ordering suffix C207,118 against the manufacturer's latest documentation to confirm package type and embedded software version. Ensure compatibility with existing host serial interface requirements before procurement. Cross-reference the revision date of the datasheet to confirm regulatory compliance status.

Specialized Selection Notes

Select this component for applications requiring a standalone smart card interface with minimal external components. Consider the embedded 80C51 core if firmware flexibility is needed without a separate host MCU. Evaluate power consumption requirements against the available low-power modes. Verify that the required smart card protocols are supported within the device's hardware capabilities.

Specialized Part Context

The TDA8029 series serves as a complete solution for smart card interfacing, combining analog drivers, a DC-to-DC converter, and a microcontroller on a single chip. It is designed to replace discrete solutions in portable devices where space and power efficiency are critical constraints. The C2 variant specifically includes standard embedded software for common card types.

Specialized Replacement Considerations

For EMVCo4.3c support, the PN7412AU is recommended as the TDA8029 is no longer compliant with this specific standard. Direct pin-compatible replacements may not exist due to the integrated microcontroller; consider redesigning the firmware layer if switching to a different smart card controller family.
