SEC1210I-CN-02-TR

Specialized Overview

The SEC1210I-CN-02-TR is a dual smart card bridge IC from Microchip Technology, designed to interface with USB and UART host systems. It integrates an enhanced 8051 microcontroller with 16 KB OTP ROM and 1.5 KB RAM. The device supports two ISO/IEC 7816 compliant smart card interfaces and operates on a 3.6V to 5.5V supply. Key electrical parameters include a maximum operating temperature of +85°C, a minimum of -40°C, and a typical operating current of 55 mA. It features a QFN-24 package and supports USB 2.0 Full Speed at 12 Mbps.

Specialized Feature Summary

• Dual smart card interface supporting Class A, B, C, and AB cards with integrated power regulation
• Integrated USB 2.0 Full Speed controller with built-in PHY and endpoint buffers
• UART interface supporting standard PC baud rates and high-speed 3 M baud operation
• Enhanced 8051 processor with self-clocking internal oscillator eliminating external crystal requirements

Specialized Applications

• USB-based dual smart card readers
• UART-based dual smart card readers
• Secure authentication modules requiring dual SIM or smart card support

Specialized Procurement Notes

Verify the specific ordering suffix CN-02 against the manufacturer's Product Identification System to confirm interface configuration and temperature grade. Ensure the component meets RoHS compliance requirements for your target market. Cross-reference the datasheet revision number to ensure compatibility with any known errata sheets published by Microchip Technology.

Specialized Selection Notes

Select this model when a single-chip solution for dual smart card communication via USB or UART is required. The SEC1210 series is appropriate for applications needing ISO/IEC 7816 compliance without external protocol controllers. Consider the industrial temperature range (-40°C to +85°C) indicated by the 'I' suffix for environments with extreme thermal conditions.

Specialized Part Context

This component belongs to the SEC1110/SEC1210 family of smart card bridges. While the SEC1110 provides a single smart card interface, the SEC1210 variant offers dual interfaces, making it suitable for multi-card applications. Both share the same core architecture, including the enhanced 8051 controller and TrustSpan technology for secure data processing.

Specialized Replacement Considerations

Direct functional replacements within the same family include the SEC1210T/PV-UR2, which shares the dual smart card interface capability but may differ in temperature rating or packaging. Verify pinout compatibility and software register mapping before substituting.
