Product details
Overview
SEC1210I-CN-02 from Microchip Technology is a dual Smart Card bridge IC integrating an enhanced 8051 core, two ISO/IEC 7816-compliant Smart Card interfaces (SC1 and SC2), USB 2.0 Full-Speed (12 Mbps) interface, UART, and SPI host controller. It delivers 16 KB OTP ROM, 1.5 KB RAM, programmable Smart Card clock (1.8V/3.0V/5.0V support), and full T=0/T=1 protocol handling - deployed in secure USB dual Smart Card readers for financial terminals and government ID systems.
For engineers reviewing the SEC1210I-CN-02 datasheet, SEC1210I-CN-02 pinout, SEC1210I-CN-02 application, or SEC1210I-CN-02 equivalent, key selection criteria include dual-card ISO7816 timing compliance (EMV 4.2/4.3), USB-to-Smart Card bridge latency (<180 ms software response), FIFO depth (261-byte full-packet), self-clocking oscillator (no external crystal), and 5.0 V-tolerant I/O for industrial reader designs.
Technical Context
The SEC1210I-CN-02 implements a dedicated Smart Card subsystem with hardware-enforced EMV timing constraints (Guard, CWT, and Timeout timers), automatic cold/warm reset sequencing, and synchronous card support via GPIO-controlled signals. Its dual Smart Card interfaces operate independently with separate VCC regulators, FIFOs, and protocol state machines.
USB functionality is handled by an integrated FS PHY with 1.5 kΩ pull-up resistor and D+/D− series termination, paired with a USB Device Controller supporting five programmable bulk/interrupt endpoints (8/16/32/64 byte buffers) and control endpoint 0 with 8/16/32/64 byte buffer. The 8051 core runs at up to 9.6 MHz with reduced instruction cycle time (≈9× standard 80C51).

FAQ
What is the operating temperature range of the SEC1210I-CN-02?
The SEC1210I-CN-02 is rated for industrial temperature operation from −40°C to +85°C. This specification is validated per Microchip's DS00001561E datasheet and applies to all electrical parameters including Smart Card voltage regulation, USB timing, and 8051 core performance - enabling deployment in outdoor kiosks, vehicle-mounted terminals, and factory-floor access panels where ambient conditions exceed commercial-grade limits.
Does the SEC1210I-CN-02 support both T=0 and T=1 Smart Card protocols?
Yes, the SEC1210I-CN-02 fully supports both T=0 and T=1 protocols per ISO/IEC 7816-3 and EMV 4.2/4.3. It includes dedicated hardware state machines for T=0 procedure byte filtering and T=1 block-level CRC checking, along with programmable protocol timers (CWT, WWT, BWT) - all implemented in silicon to guarantee timing compliance without firmware dependency.
Can the SEC1210I-CN-02 operate without an external crystal?
Yes, the SEC1210I-CN-02 uses an internal self-clocking 48 MHz oscillator - no external crystal or resonator is required. This oscillator drives the USB PHY, Smart Card clocks, and 8051 core, reducing bill-of-materials cost and PCB footprint. The oscillator is factory-trimmed and specified across the full −40°C to +85°C range with ±1.5% accuracy for USB timing compliance.
How many Smart Card interfaces does the SEC1210I-CN-02 provide?
The SEC1210I-CN-02 provides two independent ISO/IEC 7816-compliant Smart Card interfaces (SC1 and SC2), each with dedicated VCC regulators, reset generators, clock outputs, and 261-byte FIFOs. Both interfaces support Class A/B/C/AB cards (1.8V/3.0V/5.0V) and operate concurrently - confirmed in the Product Identification System table and SEC1210 block diagram (DS00001561E, page 8).
Is the SEC1210I-CN-02 pin-compatible with other SEC1210 variants?
Yes, the SEC1210I-CN-02 shares the identical 24-pin QFN package and pinout with all SEC1210 variants including SEC1210-CN-02 and SEC1210/PV-UR2. Pin functions are identical across variants; differences are limited to temperature grade (industrial vs. commercial) and factory-configured interface enablement (USB vs. UART) - verified in Tables 3-2 and 5-1 of DS00001561E.
