TDA8020HL/C1,118

Specialized Overview

The TDA8020HL/C1,118 is a dual smart card interface integrated circuit manufactured by NXP Semiconductors. It provides two independent ISO/IEC 7816 and EMV2000 compliant contacts. The device operates with a supply voltage (VDD) of 2.7 V to 6.5 V and supports card supply voltages of 3 V or 5 V. It features an integrated DC-to-DC converter for power generation. Control and status are managed via an I2C-bus interface supporting up to four parallel devices. The component is housed in an LQFP32 package (SOT358-1) and operates within an ambient temperature range of -30 °C to +85 °C.

Specialized Feature Summary

• Dual independent smart card interfaces conforming to ISO 7816 and EMV2000 standards
• Integrated DC-to-DC converter allowing operation from a wide input voltage range
• Automatic activation, deactivation, and reset sequences controlled by internal sequencers
• Comprehensive protection against overcurrent, overheating, and supply drop-outs

Specialized Applications

• Set top boxes
• Banking terminals
• Internet terminals

Specialized Procurement Notes

Verify the specific suffix /C1,118 against the manufacturer's current product database to confirm availability and exact pinout compatibility. Ensure that the LQFP32 package dimensions match the target PCB footprint. Confirm that the operating temperature range meets the environmental requirements of the final assembly.

Specialized Selection Notes

Select this component when designing systems requiring dual contact smart card readers. Ensure the host microcontroller supports the required I2C bus speeds. Verify that the system power supply can provide the necessary current for the DC-to-DC converter during peak card activation loads. Consider the thermal resistance characteristics if multiple units are placed in close proximity.
