SEC1210-I/PV-URT

Specialized Overview

The SEC1210-I/PV-URT is a smart card bridge IC providing UART interface connectivity. It features two ISO/IEC 7816 compliant smart card interfaces supporting T=0 and T=1 protocols with ETU rates up to 826 Kbps. The device integrates 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 3.6 V to 5.5 V and 5.0 V tolerance on user-accessible I/O pins. It operates within the commercial temperature range of 0°C to +70°C and utilizes a QFN-24 package.

Specialized Feature Summary

• Dual smart card interfaces fully compliant with ISO/IEC 7816, EMV, ETSI, and PC/SC standards
• Integrated enhanced 8051 microcontroller with 16 KB OTP ROM and 1.5 KB RAM
• UART interface supporting standard PC baud rates and high-speed 3 M baud operation
• Internal power regulation for 1.8 V, 3.0 V, and 5.0 V smart cards with over-current protection

Specialized Applications

• UART-based smart card readers
• Smart card bridges for embedded systems
• Secure authentication modules requiring serial communication

Specialized Procurement Notes

Verify the specific ordering suffix against official Microchip documentation to confirm interface configuration and temperature grade. Ensure compatibility with system voltage levels and protocol requirements before integration. Cross-reference datasheet revision numbers to account for any silicon errata or functional updates that may affect design implementation.

Specialized Selection Notes

Select this component when dual smart card support is required alongside a UART host interface. The integrated 8051 controller reduces external processing load compared to passive bridge solutions. Verify that the target application falls within the specified 0°C to +70°C commercial temperature range and requires the QFN-24 form factor for board space constraints.

Specialized Part Context

This part belongs to the SEC1210 family, which provides smart card bridging capabilities. Unlike the SEC1110 variant which offers only a single smart card interface, the SEC1210 supports two independent smart card slots. The -URT suffix specifically denotes the UART interface configuration, distinguishing it from USB-only or SPI-enabled variants within the same product line.

Specialized Replacement Considerations

Direct replacements must maintain dual smart card support and UART interface capability. Consider the SEC1210T/PV-UR2 if USB interface functionality is required instead of UART. Verify pinout compatibility and software driver availability when substituting with other Microchip smart card bridge ICs.
