SEC1210-CN-02NC

Specialized Overview

The SEC1210-CN-02NC is a dual smart card bridge IC manufactured by Microchip Technology. It integrates two ISO/IEC 7816 compliant smart card interfaces and supports host communication via UART or SPI, as indicated by the 'CN' suffix in the product identification system. The device features an enhanced 8051 microcontroller with 16 KB OTP ROM and 1.5 KB RAM. Electrical specifications include a supply voltage range of 3.6 V to 5.5 V, a maximum operating temperature of +70°C for the commercial variant, and support for Class A, B, C, and AB smart cards at 1.8 V, 3.0 V, and 5.0 V.

Specialized Feature Summary

• Dual smart card interface supporting T=0 and T=1 protocols with full-packet FIFO
• Integrated USB 2.0 controller with PHY and programmable endpoint buffers
• Enhanced 8051 processor with internal oscillator and hardware power management

Specialized Applications

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

Specialized Procurement Notes

Verify the specific ordering suffix against the manufacturer's Product Identification System documentation to confirm interface selection and temperature grade. Ensure the selected variant matches the required host communication protocol and environmental operating conditions for the target application design.

Specialized Selection Notes

Select this component when a single-chip solution for bridging smart cards to host interfaces is required. Consider the integrated USB capabilities and dual card support. Verify that the commercial temperature range meets the system requirements and that the OTP programming infrastructure is available for firmware deployment.

Specialized Part Context

This part belongs to the SEC1210 family within the SEC1110/SEC1210 series. These devices provide a unified platform for smart card access, combining standard interface compliance with embedded processing capabilities. The family distinguishes between single and dual card variants and offers flexible host connectivity options.

Specialized Replacement Considerations

The SEC1110 serves as a single-card interface alternative within the same family. Other SEC1210 variants with different suffixes may offer UART-only or SPI-only host connections instead of the combined configuration.
