TDA8026ET/C2,551

Specialized Overview

The TDA8026ET/C2,551 is a multiple smart card slot interface IC designed for Point Of Sale terminals. It addresses up to two main cards and four Security Access Modules via an I2C-bus controlled interface in a TFBGA64 package. The device supports supply voltages between 2.7 V and 5.5 V with a dedicated microcontroller interface supply of 1.6 V to 3.6 V. It features five protected half-duplex bidirectional buffered I/O lines with current limitation at ±15 mA and a maximum frequency of 1 MHz. Card presence detection includes a built-in debouncing system with a typical time of 17.8 ms.

Specialized Feature Summary

• I2C-bus controlled IC card interface supporting synchronous and asynchronous smart cards
• Integrated DC-to-DC converter generating regulated VCC(n) supplies for card slots
• Programmable power reduction modes triggered when card slots are inactive
• Enhanced ElectroStatic Discharge protection on the card-side up to 6 kV

Specialized Applications

• Point Of Sale terminals
• Multiple SAM contact readers

Specialized Procurement Notes

Verify the specific ordering suffix C2 against the official NXP datasheet to confirm compliance requirements. Ensure the TFBGA64 package variant matches the design footprint. Confirm RoHS and REACH status through the manufacturer's product data sheet or certificate of analysis before finalizing procurement specifications.

Specialized Selection Notes

Select this component when designing POS systems requiring multiple smart card interfaces within a compact form factor. The TDA8026ET/C2 version provides standard functionality compatible with ISO 7816-3 and EMV standards. Consider the C3 version if specific EMVC0 4.3 compliance is required, as both versions share identical electrical performance and pinout configurations.

Specialized Part Context

The TDA8026 series serves as a cost-effective analog interface for addressing multiple smart card slots in payment terminals. Manufactured by NXP Semiconductors, it integrates voltage supervisors, thermal protection, and short-circuit protection. The device simplifies system design by handling card sequencing and power management internally.

Specialized Replacement Considerations

The TDA8026ET/C3 is a functional substitute with identical electrical characteristics. Verify that the C3 version meets any specific regulatory compliance needs not addressed by the C2 version.
