TDA8023TT/C1,118

Specialized Overview

The TDA8023TT/C1,118 is a low-power analog interface for synchronous or asynchronous smart cards. It operates with a supply voltage range of 2.7 V to 6.5 V and features an integrated DC-to-DC converter generating 5 V, 3 V, or 1.8 V outputs. The device includes one protected half-duplex bidirectional I/O line limited at ±15 mA with a maximum frequency of 1 MHz, plus two auxiliary I/O lines (C4 and C8). It supports a 20 MHz clock input and generates card clocks up to 10 MHz. Power consumption in shutdown mode is less than 10 µA.

Specialized Feature Summary

• I2C-bus controlled IC card interface
• Integrated DC-to-DC converter for VCC generation
• Enhanced ESD protection on card side exceeding 6 kV
• Supply voltage supervisor for spike killing

Specialized Applications

• Banking terminals
• Internet terminals
• Set-top boxes
• Portable IC card readers

Specialized Procurement Notes

Verify the specific ordering suffix 'C1,118' against official NXP documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with existing PCB layouts using the TSSOP28 package. Confirm that the required external components for the DC-to-DC converter match the capacitive or inductive configurations detailed in the datasheet.

Specialized Selection Notes

Select this component when designing systems requiring a complete analog interface for ISO 7816-3, GSM 11.11, and EMVCo 4.3 compatible smart cards. It is suitable for applications needing independent interface supply voltages and low power consumption during inactive periods. Consider the TSSOP28 package constraints and the need for external decoupling capacitors for the DC-to-DC converter.

Specialized Part Context

The TDA8023 serves as a cost-efficient solution for managing smart card connections in embedded systems. It bridges microcontrollers and smart cards by handling all necessary supply, protection, and control functions. This integration reduces the number of external components required, simplifying the design process for portable and fixed card reader applications.

Specialized Replacement Considerations

The TDA8024 is mentioned as a successor in some contexts, but direct replacement requires verifying pinout and feature parity. No other specific substitute part numbers are confirmed in the provided documentation.
