Product details

Smart card interface with flexible host connectivity

The Microchip SEC1210-I/PV-UR2 is a specialized interface IC designed for smart card reader applications, handling the electrical-level translation and protocol sequencing between a smart card and a host controller. It supports both 3V and 5V smart cards directly, thanks to a supply range of 3V to 5.5V, which covers the two common card voltage standards without an external regulator. The part communicates with the host through any of three interfaces: SPI Serial, USB, or UART, giving the designer flexibility in how it connects to the system MCU or SoC.

3V to 5.5V supply — covers both card standards

The supply voltage range of 3V to 5.5V is the headline spec for this part. It means the SEC1210-I/PV-UR2 can power a 5V smart card from a 5V rail, or a 3V card from a 3.3V rail, without needing a separate level shifter. This simplifies the power tree and reduces BOM cost. If your design targets dual-voltage card support, this single IC handles both.

24-QFN with exposed pad — thermal and layout notes

The part comes in a 24-VFQFN Exposed Pad package (5x5 mm body), surface-mount only. The 24-QFN footprint is compact, suited for space-constrained reader modules or handheld terminals.

ROHS3 compliant.

Frequently asked questions

Is SEC1210-I/PV-UR2 compatible with 5V smart cards?

Yes. The supply voltage range of 3V to 5.5V covers the 5V smart card standard directly, so no external level translation is needed for 5V cards.

Is SEC1210-I/PV-UR2 compatible with 3V smart cards?

Yes. The 3V to 5.5V supply range also covers 3V smart cards. The part handles both 3V and 5V card voltages without additional components.

What interfaces does SEC1210-I/PV-UR2 support?

It supports SPI Serial, USB, and UART interfaces, giving flexible connectivity to a host microcontroller or system-on-chip.

What is the difference between SEC1210-I/PV-UR2 and SEC1210-I/PV?

The difference is in the packaging and shipping medium: SEC1210-I/PV-UR2 ships in Tray format, while the SEC1210-I/PV variant may ship in a different medium. The die and electrical specifications are identical.
