TDA8026ET/C2,518

Specialized Overview

The TDA8026ET/C2,518 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 in a TFBGA64 package. The device operates with a supply voltage between 2.7 V and 5.5 V and features an I2C-bus controlled interface. It includes a DC-to-DC converter generating VCC(n) voltages of 5 V, 3 V, or 1.8 V with ±5% accuracy. Key electrical parameters include a maximum clock frequency of 20 MHz, current limitation of ±15 mA on I/O lines, and shutdown mode current consumption of 25 µA.

Specialized Feature Summary

• Supports up to five smart card slots with integrated power management
• I2C-bus controlled interface for microcontroller communication
• Integrated DC-to-DC converter for flexible card supply voltages
• Enhanced ESD protection and thermal/short-circuit safeguards

Specialized Applications

• Point of Sale (POS) terminals
• Multiple SAM contact readers

Specialized Procurement Notes

Verify the specific ordering suffix C2 against the official datasheet to confirm compliance requirements. Ensure the TFBGA64 package type matches the design constraints. Confirm that the component version aligns with the required EMVCo standards for the target application.

Specialized Selection Notes

Select this component when designing systems requiring multiple simultaneous smart card interfaces within a compact footprint. Consider the TFBGA64 package for space-constrained PCB layouts. Evaluate the power modes to optimize energy consumption during idle periods in portable devices.

Specialized Part Context

This part belongs to the TDA8026 series of analog interface ICs from NXP Semiconductors. It serves as a specialized solution for managing smart card communications in payment terminals. The series provides robust hardware support for ISO 7816-3 and EMV protocols.

Specialized Replacement Considerations

The TDA8026ET/C3 is a functional alternative within the same series. Verify if the C3 version meets specific EMVC0 4.31 compliance requirements not present in the C2 variant.
