SEC1210T-I/PV-UR2

Specialized Overview

The SEC1210T-I/PV-UR2 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. Electrical specifications include a supply voltage range of 3.6V to 5.5V, a maximum operating current of 55 mA, and support for baud rates up to 3 Mbps on the UART interface. It operates within a commercial temperature range of 0°C to +70°C and is housed 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 with hardware-managed protocol timers and FIFOs
• Internal power regulation supporting multiple smart card voltage classes

Specialized Applications

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

Specialized Procurement Notes

Verify the specific suffix UR2 indicates reel packaging when sourcing components. Confirm the -I designation corresponds to the required commercial temperature range for your application environment. Ensure compatibility with the QFN-24 footprint during PCB layout. Cross-reference the datasheet revision to confirm pinout consistency before finalizing procurement orders.

Specialized Selection Notes

Select this component when a single-chip solution for dual smart card management via USB or UART is required. It is suitable for designs needing integrated protocol handling for T=0 and T=1 without external controllers. Consider the internal oscillator and lack of crystal requirement for simplified board design. Evaluate the 16 KB OTP capacity against firmware size requirements for custom driver implementations.

Specialized Part Context

This part 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 distinct for multi-card applications. The SEC1210T-I/PV-UR2 specifically denotes the industrial/commercial grade version with UART/USB capabilities in a tray/reel configuration depending on the exact suffix interpretation, though the core functionality remains consistent with the SEC1210 series.

Specialized Replacement Considerations

Direct substitutes are limited within the same family. The SEC1210T-I/PV-URT serves as a functional alternative if only one smart card interface is needed. Verify pin-to-pin compatibility and firmware compatibility if migrating between variants within the SEC1210 series.
