SEC1110-A5-02NC-TR

Specialized Overview

The SEC1110-A5-02NC-TR is a smart card bridge IC from Microchip Technology, providing a single-chip solution for connecting smart cards to USB interfaces. It features an enhanced 8051 microcontroller with 16 KB OTP ROM and 1.5 KB RAM. The device supports USB 2.0 Full Speed (12 Mbps) operation and includes a comprehensive smart card interface compliant with ISO/IEC 7816, EMV, and PC/SC standards. It operates within a supply voltage range of 3.0 V to 5.5 V, with a maximum operating current of 55 mA. The component is housed in a QFN-16 package and is rated for commercial temperature ranges from 0°C to +70°C.

Specialized Feature Summary

• Integrates an enhanced 8051 microcontroller with 16 KB OTP ROM and 1.5 KB RAM for embedded application control.
• Provides a full-packet FIFO of 261 bytes for smart card transmit and receive operations, supporting half-duplex communication without software intervention.
• Includes an integrated USB 2.0 Full Speed PHY with built-in pull-up and series termination resistors.
• Supports Class A, B, C, and AB smart cards with internal power regulation for 1.8V, 3.0V, and 5.0V supplies.

Specialized Applications

• USB-based smart card readers
• Secure authentication devices requiring USB connectivity
• Embedded systems interfacing with ISO/IEC 7816 compliant smart cards

Specialized Procurement Notes

Verify the specific ordering suffix -A5-02NC-TR against the manufacturer's Product Identification System to confirm package type, temperature grade, and tape-and-reel packaging details. Ensure compatibility with the required USB descriptor configuration and smart card protocol requirements before integration into the final design.

Specialized Selection Notes

Select this component when a single-chip USB-to-smart-card bridge is required with embedded processing capabilities. The SEC1110 variant is appropriate for applications needing only one smart card interface, unlike the SEC1210 which supports dual interfaces. Consider the QFN-16 package constraints and thermal management requirements for the PCB layout.

Specialized Part Context

This part belongs to the SEC1110/SEC1210 family of smart card bridges. The SEC1110 specifically provides a single smart card interface connected via USB, whereas the SEC1210 offers dual smart card interfaces and additional UART/SPI options. The -TR suffix indicates reel packaging, distinguishing it from tray-packaged variants like the SEC1110-A5-02.

Specialized Replacement Considerations

Direct substitutes include other parts within the SEC1110 family with different packaging or temperature ratings, such as SEC1110-A5-02. Cross-family replacements are not directly documented; verify functional equivalence with SEC1210 variants if dual card support is needed.
