TDA8026ET/C3E

Specialized Overview

The TDA8026ET/C3E is a multiple smart card slot interface IC designed for Point Of Sale terminals. It supports up to two main cards and four Security Access Modules within a TFBGA64 package. The device operates with a supply voltage between 2.7 V and 5.5 V, featuring a dedicated microcontroller interface supply of 1.6 V to 3.6 V. It includes an integrated DC-to-DC converter generating regulated 5 V, 3 V, or 1.8 V outputs with ±5% accuracy. Key electrical parameters include a shutdown current of 25 µA typical, active mode current of 210 mA typical, and I/O lines limited to 15 mA at 1 MHz.

Specialized Feature Summary

• I2C-bus controlled interface in a TFBGA64 package
• Integrated DC-to-DC converter for card supply generation
• Programmable power reduction modes triggered by inactive slots
• Enhanced ESD protection on card-side up to 6 kV

Specialized Applications

• Point Of Sale terminals
• Multiple SAM contact readers

Specialized Procurement Notes

Verify the specific ordering suffix against official documentation to confirm compliance version. The C3 variant ensures compatibility with EMVCo 4.31 standards. Confirm package details match the TFBGA64 specification. Ensure all procurement channels provide original manufacturer documentation to validate authenticity and revision history.

Specialized Selection Notes

Select this component when designing POS systems requiring multiple simultaneous smart card interfaces. Verify that the system controller supports the required I2C bus speeds. Ensure the PCB layout accommodates the external components needed for the DC-to-DC converter operation. Check thermal dissipation requirements based on the total power dissipation specifications under maximum load conditions.

Specialized Part Context

The TDA8026 series serves as an analog interface solution for addressing multiple smart card slots in payment terminals. It allows manufacturers to integrate synchronous and asynchronous smart card support alongside Security Access Modules efficiently. The packaging is designed to meet modern payment terminal security requirements while maintaining cost-effectiveness.

Specialized Replacement Considerations

The TDA8026ET/C2 is a functional alternative with identical hardware capabilities but different compliance certification. Both versions utilize the same TFBGA64 package and pinout. Select the C2 version only if EMVCo 4.31 compliance is not a strict requirement for the target application.
