SEC1210T/PV-UR2

Specialized Overview

The SEC1210T/PV-UR2 is a dual smart card bridge IC manufactured by Microchip Technology, designed to interface with USB and UART host systems. It integrates an enhanced 8051 microcontroller with 16 KB OTP ROM and 1.5 KB RAM. The device supports two smart card interfaces compliant with ISO/IEC 7816 and EMV standards, handling Class A, B, C, and AB cards (1.8V, 3.0V, 5.0V). Key electrical parameters include a supply voltage range of 3.6V to 5.5V, a maximum operating current of 55 mA, and a maximum clock speed of 9.6 MHz. It operates within a commercial temperature range of 0°C to +70°C and utilizes a QFN-24 package.

Specialized Feature Summary

• Dual smart card interface supporting T=0 and T=1 protocols with full-packet FIFO for half-duplex operation.
• Integrated USB 2.0 controller with built-in PHY and programmable endpoint buffers.
• Embedded enhanced 8051 processor with self-clocking internal oscillator eliminating external crystal requirements.
• Hardware-managed power regulation for 1.8V, 3.0V, and 5.0V smart cards with over-current protection.

Specialized Applications

• USB-based smart card readers
• UART-based smart card readers
• Dual smart card reader devices

Specialized Procurement Notes

Verify the specific ordering suffix UR2 against the manufacturer's Product Identification System documentation to confirm interface configuration and package type. Ensure that the required quantity aligns with the factory reel packaging specifications provided in the official datasheet. Confirm RoHS compliance status through the latest product release notes before finalizing procurement orders.

Specialized Selection Notes

Select this component when a single-chip solution is required for bridging dual smart card slots to a host via USB or UART. The SEC1210 is appropriate for designs needing integrated power regulation for multiple voltage classes without external components. Consider the 8051 architecture if firmware development tools compatible with this core are available for the application.

Specialized Part Context

This part belongs to the SEC1210 series, which provides smart card bridge functionality. It differs from the SEC1110 by offering two smart card interfaces instead of one and including additional host interface options such as UART and SPI. The SEC1210 serves as a comprehensive interface controller for secure identification applications requiring multi-card support.

Specialized Replacement Considerations

The SEC1110 is a related variant within the same family but provides only a single smart card interface. Verify functional equivalence regarding the number of supported smart card slots and host interface requirements before substituting.
