SEC1210-CN-02

Specialized Overview

The SEC1210-CN-02 is a dual smart card bridge IC manufactured by Microchip Technology. It interfaces two ISO/IEC 7816 compliant smart cards to a host via UART or SPI, while also supporting USB connectivity in the broader SEC1210 family. The device integrates an enhanced 8051 microcontroller with 16 KB OTP ROM and 1.5 KB RAM. Electrical specifications include a supply voltage range of 3.6V to 5.5V, a maximum clock speed of 9.6 MHz for the CPU, and support for baud rates up to 3 Mbps on the UART interface. It operates within commercial temperature ranges.

Specialized Feature Summary

• Dual smart card interface supporting Class A, B, C, and AB cards with automatic power regulation.
• Integrated enhanced 8051 processor with hardware protocol handling for T=0 and T=1 standards.
• Flexible host connectivity options including UART and SPI interfaces.

Specialized Applications

• UART-based dual smart card readers
• SPI-based smart card terminals
• Security authentication modules requiring dual SIM access

Specialized Procurement Notes

Verify the specific ordering suffix against the manufacturer's Product Identification System to confirm interface selection. Ensure the selected variant matches the required host communication protocol for the target design.

Specialized Selection Notes

Select this component when a single-chip solution for dual smart card management is required. Consider the integrated 8051 controller for applications needing embedded protocol processing without an external MCU.

Specialized Part Context

This part belongs to the SEC1110/SEC1210 series of smart card bridges. While the SEC1110 supports a single card interface, the SEC1210 provides dual interfaces. The CN suffix typically denotes specific package or interface configurations within the product line.

Specialized Replacement Considerations

The SEC1210/PV-UR2 is a documented alternative within the same family offering dual smart card support with different interface characteristics.

Specialized FAQ

Does the SEC1210-CN-02 support simultaneous USB and UART connections?

No, the SEC1210 interfaces to the host via either USB or UART/SPI, but not both simultaneously.

What smart card classes are supported by this device?

The device supports Class A (1.8V), Class B (3.0V), Class C (5.0V), and Class AB smart cards.
