SEC1210-CN-02NC-TR

Specialized Overview

The SEC1210-CN-02NC-TR is a dual smart card bridge IC from Microchip Technology, designed to interface with USB and UART host systems. It integrates two ISO/IEC 7816 compliant smart card interfaces, supporting Class A, B, C, and AB cards with voltages of 1.8V, 3.0V, and 5.0V. The device features an enhanced 8051 microcontroller with 16 KB OTP ROM and 1.5 KB RAM, operating at a maximum clock speed of 9.6 MHz. It supports USB 2.0 Full Speed (12 Mbps) and UART communication up to 3 M baud. The component operates within a supply voltage range of 3.6V to 5.5V and is available in a QFN-24 package.

Specialized Feature Summary

• Dual smart card interfaces fully compliant with ISO/IEC 7816, EMV, ETSI, and PC/SC standards
• Integrated USB 2.0 Full Speed controller with built-in PHY and endpoint buffers
• Embedded enhanced 8051 processor for direct peripheral control via SFR or XDATA registers
• Supports T=0 and T=1 protocols with automatic half-duplex turnaround and protocol timers

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-02NC-TR against the manufacturer's current product identification system to confirm package type, temperature range, and tape-and-reel packaging status. Ensure compatibility with existing PCB footprints for the QFN-24 package and validate power supply requirements before integration.

Specialized Selection Notes

Select this component when a single-chip solution for dual smart card management is required alongside USB or UART connectivity. It is suitable for applications needing robust protocol handling for T=0/T=1 without external protocol controllers. Consider the integrated 8051 resources for firmware implementation needs.

Specialized Part Context

This part belongs to the SEC1210 family, which provides dual smart card interfaces compared to the single-interface SEC1110. The SEC1210 variant supports both USB and UART host connections, offering flexibility in system design for smart card reader implementations.

Specialized Replacement Considerations

The SEC1210/PV-UR2 is a documented alternative within the same family, providing dual smart card interfaces with UART and USB capabilities. Verify pinout and register compatibility if substituting.
