TDA8029HL/C207,151

Specialized Overview

The TDA8029HL/C207,151 is a complete single-chip smart card reader manufactured by NXP Semiconductors. It integrates an 80C51 core with 16 kB ROM, 256 byte RAM, and 512 byte XRAM. The device supports ISO 7816 asynchronous protocols T=0 and T=1, featuring a specific UART for automatic convention processing and variable baud rates. It includes a versatile 24-bit Elementary Time Unit (ETU) counter for timing processing during Answer To Reset (ATR) and protocol execution. The TDA8029 provides controlled VCC generation up to 65 mA at 5 V, card clock generation up to 20 MHz, and multiple power reduction modes including shut-down, sleep, and power-down states.

Specialized Feature Summary

• Integrated 80C51 microcontroller with dedicated memory and enhanced serial communication capabilities
• Hardware support for ISO 7816 T=0 and T=1 asynchronous protocols with automatic error management
• Built-in DC-to-DC converter enabling wide supply voltage operation from 2.7 V to 6 V
• Multiple low-power operating modes with independent sequencer for activation and deactivation sequences

Specialized Applications

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

Specialized Procurement Notes

Verify the exact ordering suffix against the manufacturer's current documentation to ensure package type and embedded software version match project requirements. Confirm RoHS compliance status and material declarations prior to procurement. Check for any discontinued status or lifecycle notices associated with this specific part number variant before finalizing orders.

Specialized Selection Notes

Select this component when designing portable or general-purpose smart card interfaces requiring low power consumption and integrated protocol handling. Ensure the host system can interface via standard full-duplex serial link. Verify that the required card supply voltage and current limits align with the device's DC-to-DC converter capabilities and output specifications.

Specialized Part Context

The TDA8029 series belongs to NXP's portfolio of low-cost, low-power smart card reader solutions. It is designed for portable equipment where power efficiency and robust hardware control are critical. The device simplifies design by integrating the microcontroller, analog drivers, and power management into a single LQFP32 package.

Specialized Replacement Considerations

For EMVCo 4.3c support, the PN7412AU is recommended as the TDA8029 is no longer compliant with this specific standard. Direct functional replacements should be evaluated based on pin compatibility and embedded software library availability.
