TDA8007BHL/C2,118

Specialized Overview

The TDA8007BHL/C2,118 is a double multiprotocol IC card interface designed for dual smart card readers. It supports asynchronous protocols T=0 and T=1 per ISO 7816 and EMV 3.1.1 standards. The device features an integrated ISO UART with parallel access, automatic convention processing, and variable baud rate programming. It provides dual VCC generation (5 V ± 5%, 3 V ± 8%, or 1.8 V ± 10%) and dual card clock generation up to 10 MHz. Controlled via an 8-bit parallel interface compatible with multiplexed or non-multiplexed memory access, it includes current limitation, short-circuit detection, and enhanced ESD protection (>6 kV). The unit operates within a supply voltage range of 2.7 to 6 V using an internal step-up converter.

Specialized Feature Summary

• Integrated ISO UART with FIFO reception and automatic re-transmission capabilities
• Dual independent card interfaces with separate buffering for fast swapping
• Built-in step-up converter enabling operation from low supply voltages
• Hardware-based security features including ESD protection and power supervision

Specialized Applications

• Multiple smart card readers for multiprocessor applications
• EMV banking terminals
• Digital pay TV systems
• Access control systems

Specialized Selection Notes

Select this component for designs requiring dual smart card support with minimal microcontroller overhead. The integrated UART handles protocol timing, reducing CPU load. Choose the C2 version for EMV 3.1.1 compliance. Ensure the host system can provide the necessary 8-bit parallel interface signals (D0-D7, RD, WR, CS, ALE/AD0-AD3). Verify that the external crystal frequency falls within the 4 to 20 MHz range for proper clock generation.

Specialized Part Context

The TDA8007B is part of NXP's (formerly Philips Semiconductors) smart card interface portfolio. It serves as a cost-effective solution for dual reader applications, succeeding earlier single-interface designs. The device simplifies reader implementation by integrating analog drivers, sequencers, and the ISO UART into a single LQFP48 package, reducing board space and component count compared to discrete solutions.

Specialized Replacement Considerations

The TDA8007BHL/C3 is a software-compatible alternative offering support for ISO 7816 and EMV 2000 standards in addition to EMV 3.1.1. When replacing, verify that the application does not rely on specific timing parameters unique to the C2 variant, such as the minimum delay between characters in reception mode.

Specialized 118

corresponds to the LQFP48 package variant as specified in the datasheet. Confirm that the specific C2 designation matches the required protocol compliance (ISO 7816 and EMV 3.1.1) versus the C3 variant. Ensure compatibility with the target microcontroller's bus configuration before procurement.
