SEC1210/PV-URT

Specialized Overview

The SEC1210/PV-URT is a single-chip Smart Card bridge to UART interface manufactured by Microchip Technology. It 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. The device supports one Smart Card interface compliant with ISO/IEC 7816, EMV 4.2/4.3, ETSI TS 102 221, and PC/SC standards, handling Class A, B, C, and AB cards (1.8V, 3.0V, 5.0V). It includes a full-packet FIFO of 261 bytes for transmit and receive, supporting T=0 and T=1 protocols with ETU rates up to 826 Kbps. The UART interface supports standard PC baud rates and a high-speed rate of 3 M baud. Power supply input ranges from 3.6V to 5.5V, with user-accessible I/O pins tolerant to 5.0V.

Specialized Feature Summary

• Provides a unified solution for bridging Smart Card interfaces to UART communication.
• Integrates an enhanced 8051 microcontroller for direct peripheral control via SFR or XDATA registers.
• Supports comprehensive Smart Card protocol compliance including ISO/IEC 7816 and EMV standards.
• Features internal power regulation for multiple voltage classes and automatic card deactivation sequences.

Specialized Applications

• UART-based Smart Card readers
• Dual Smart Card reader systems utilizing the second slot via SPI or GPIO
• Secure identification terminals requiring TrustSpan technology integration

Specialized Procurement Notes

Verify the specific ordering suffix PV-URT confirms the UART host interface configuration, as other suffixes may indicate USB connectivity. Ensure the QFN-24 package variant matches the design footprint requirements. Confirm that the commercial temperature range (0ºC to +70ºC) aligns with the operational environment specifications before finalizing procurement orders.

Specialized Selection Notes

Select this component when a UART interface is required instead of USB for the host connection. The SEC1210 variant provides two Smart Card slots, whereas the SEC1110 offers only one. Consider the 16 KB OTP ROM capacity for firmware storage needs. Verify that the 3.6V to 5.5V supply range fits the system power architecture, noting the internal 4.8V comparator behavior regarding Class A card support.

Specialized Part Context

The SEC1210 belongs to the SEC1110/SEC1210 family of Smart Card bridge ICs. While the SEC1110 connects exclusively via USB, the SEC1210 offers flexibility with either USB or UART host interfaces. This specific part utilizes the UART option, distinguishing it from the UR2 variant which supports dual Smart Card interfaces with USB connectivity. The family shares a common core architecture based on the enhanced 8051 processor.

Specialized Replacement Considerations

The SEC1110 serves as a functional substitute if only a single Smart Card interface and USB connectivity are sufficient. For dual Smart Card applications requiring USB, the SEC1210T/PV-UR2 is the appropriate alternative within the same product family.
