TDA8007BHL/C3,118

Specialized Overview

The TDA8007BHL/C3,118 is a multiprotocol IC card interface designed for dual smart card readers. It supports ISO 7816, GSM 11-11, and EMV standards via an 8-bit parallel bus with optional multiplexed access. The device integrates an ISO UART, FIFO buffers, and time-out counters to manage asynchronous protocols T=0 and T=1. It features dual VCC generation (5V/3V/1.8V) and clocks up to 10 MHz. Operating within a supply voltage range of 2.7 V to 6 V, it includes a step-up converter, enhanced ESD protection, and power-down modes.

Specialized Feature Summary

• Supports asynchronous protocols T=0 and T=1 with automatic convention processing and variable baud rates.
• Integrates dual card interfaces with independent sequencers for activation and deactivation sequences.
• Provides flexible addressing through non-multiplexed or multiplexed memory access configurations.
• Includes hardware protections against short-circuiting, power failure, and ESD events.

Specialized Applications

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

Specialized Procurement Notes

Verify the ordering suffix C3 indicates support for both multiplexed and non-multiplexed access modes, whereas C4 variants are restricted to non-multiplexed access only. Confirm package specifications match the LQFP48 form factor. Ensure compatibility with the required crystal frequency range of 4 MHz to 20 MHz for the intended system design.

Specialized Selection Notes

Select this component when designing dual-slot smart card readers requiring ISO 7816 compliance. Choose the C3 variant if multiplexed bus interfacing with microcontrollers like the 80C51 is necessary. Consider the integrated step-up converter for low-voltage operation scenarios where supply rails may drop below standard logic levels.

Specialized Part Context

This device belongs to NXP's smart card interface family, specifically engineered for high-security applications. It serves as a cost-effective solution for implementing robust card reader functionalities in portable and stationary devices. The integration of analog drivers and digital control reduces external component count compared to discrete solutions.

Specialized Replacement Considerations

TDA8007BHL/C4 offers identical functionality but restricts operation to non-multiplexed access only. Verify that any substitute maintains the LQFP48 package dimensions and pinout compatibility to ensure direct board replacement without redesign.
