SEC1210T/PV-URT

Specialized Overview

The SEC1210T/PV-URT is a single-chip Smart Card bridge to UART interface manufactured by Microchip Technology. It integrates an enhanced 8051 microcontroller with two Smart Card interfaces compliant with ISO/IEC 7816, EMV 4.2/4.3, ETSI TS 102 221, and PC/SC standards. The device supports T=0 and T=1 protocols with ETU rates up to 826 Kbps and includes a full-packet FIFO of 261 bytes for transmit and receive operations. It operates on a 3.6V to 5.5V supply input and features a self-clocking internal oscillator eliminating the need for external crystals. The component is housed in a QFN-24 package.

Specialized Feature Summary

• Dual Smart Card interfaces supporting Class A, B, C, and AB cards with automatic power regulation and deactivation sequences.
• Integrated USB 2.0 controller with 12 Mbps operation capability alongside UART interface support.
• Enhanced 8051 processor with 9.6 MHz maximum clock speed and 16 KB OTP ROM.
• Comprehensive protocol timer management including Guard, Timeout, and CWT timers for EMV compliance.

Specialized Applications

• UART-based Smart Card readers
• Dual Smart Card reader systems
• Secure authentication modules

Specialized Procurement Notes

Verify the specific suffix UR2 against official documentation if dual interface functionality is required, as the URT suffix typically denotes UART-only configuration. Confirm moisture sensitivity levels and reflow soldering profiles prior to assembly. Ensure the QFN-24 thermal pad connection requirements are met during PCB design to maintain optimal thermal performance and electrical reliability.

Specialized Selection Notes

Select this component when a single-chip solution bridging Smart Cards to a host via UART is required. It is suitable for applications needing dual card slots without USB connectivity overhead. Consider the 16 KB OTP ROM size for firmware storage needs. Verify that the 3.6V to 5.5V operating voltage range aligns with the system power architecture.

Specialized Part Context

This part belongs to the SEC1210 series, which provides dual Smart Card interfaces. Unlike the SEC1110 which offers only one interface, the SEC1210 supports two. The URT suffix indicates UART interface availability, whereas other suffixes like UR2 may include USB capabilities. The series is designed for secure communication and processing of smart card data across various network environments.

Specialized Replacement Considerations

The SEC1210/PV-UR2 is a confirmed substitute offering dual Smart Card interfaces with both USB and UART capabilities. Ensure the application does not require the USB functionality if replacing with the URT variant, or verify compatibility if moving from URT to UR2.

Specialized FAQ

Does the SEC1210T/PV-URT support USB connectivity?

No, the URT suffix indicates that this specific variant supports UART interface only. The SEC1210 series can support USB, but that functionality is associated with different ordering suffixes such as UR2.

What Smart Card standards does the SEC1210 comply with?

The device is fully compliant with ISO/IEC 7816, EMV 4.2/4.3, ETSI TS 102 221, and PC/SC standards.

Can the SEC1210 handle both T=0 and T=1 protocols?

Yes, the device provides full support for both T=0 and T=1 Smart Card protocols.
