TDA8007BHL/C4,118

Specialized Overview

The TDA8007BHL/C4,118 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. The device features an integrated ISO UART, FIFO buffers, and time-out counters. It provides dual VCC generation (5 V at 65 mA, 3 V at 50 mA, or 1.8 V at 30 mA) 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 and enhanced ESD protection.

Specialized Feature Summary

• Integrated ISO UART with automatic convention processing and variable baud rate programming
• Dual independent card interfaces supporting asynchronous protocols T=0 and T=1
• Built-in step-up converter enabling operation from low supply voltages
• 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 C4 suffix indicates non-multiplexed access only. Confirm package type matches LQFP48 SOT313-2. Check RoHS compliance status as datasheet may vary by revision. Ensure ordering quantity aligns with distributor minimums.

Specialized Selection Notes

Select this component when dual card support is required without multiplexed bus complexity. The C4 variant simplifies design by fixing the communication mode. Consider the C3 version if multiplexed address/data bus compatibility with controllers like 80C51 is necessary.

Specialized Part Context

This part belongs to the TDA8007BHL family of smart card interfaces. The C4 suffix specifically denotes the non-multiplexed configuration variant. It serves as a cost-effective solution for high-security card reader implementations requiring robust hardware protection and flexible protocol support.

Specialized Replacement Considerations

TDA8007BHL/C3 offers identical functionality but supports both multiplexed and non-multiplexed configurations. Verify pin compatibility and software library updates when substituting between C3 and C4 variants.
