TDA8020HL/C2,151

Specialized Overview

The TDA8020HL/C2 is a dual smart card interface integrated circuit designed for microprocessor-based applications. It provides two independent ISO 7816 and EMV 2000 compliant interfaces controlled via an I²C-bus. The device supports supply voltages from 2.7 V to 6.5 V, utilizing an integrated DC-to-DC converter to generate 3 V or 5 V card supplies with currents up to 55 mA and 60 mA respectively. It features automatic activation sequences, voltage supervision, and protection against overcurrent and overheating. The component is housed in a 32-lead LQFP package (SOT358-1) and operates within an ambient temperature range of -40 °C to +85 °C.

Specialized Feature Summary

• Dual independent smart card interfaces supporting asynchronous communication protocols
• Integrated DC-to-DC converter enabling operation from low input voltages
• Automatic activation, deactivation, and reset sequencing compliant with ISO 7816 standards
• Comprehensive protection mechanisms including current limiting and thermal shutdown

Specialized Applications

• Set top boxes
• Banking terminals
• Internet terminals

Specialized Procurement Notes

Verify the specific ordering suffix /C2 confirms the extended industrial temperature range of -40 °C to +85 °C, distinct from the /C1 variant. Confirm the package designation matches the LQFP32 plastic low profile quad flat package specification. Ensure compatibility with the host controller's I²C bus voltage levels before integration.

Specialized Selection Notes

Select this component when designing systems requiring simultaneous connection to two smart cards. The integrated sequencer reduces external component count compared to discrete solutions. Verify that the system power supply falls within the 2.7 V to 6.5 V range to ensure proper operation of the internal DC-to-DC converter and voltage supervisor circuits.
