Product details
Overview
SEC1210-I/PV-URT from Microchip Technology is a dual-interface Smart Card bridge IC supporting UART host interface and two ISO/IEC 7816-compliant Smart Card slots. It integrates an enhanced 8051 core (9.6 MHz max), 16 KB OTP ROM, 1.5 KB RAM, and on-chip Smart Card power regulation (1.8V/3.0V/5.0V). Designed for secure payment terminals and dual-slot card readers, it delivers full T=0/T=1 protocol support, 261-byte full-packet FIFO per slot, and EMV 4.2/4.3 timing compliance.
For engineers reviewing the SEC1210-I/PV-URT datasheet, SEC1210-I/PV-URT pinout, SEC1210-I/PV-URT application, or SEC1210-I/PV-URT equivalent, key selection criteria include UART host interface capability, dual Smart Card slot support with independent power control, EMV-compliant protocol timers (CWT/Guard/Timeout), 5.0V-tolerant I/O, and industrial temperature range (-40°C to +85°C) operation.
Technical Context
The SEC1210-I/PV-URT implements a dual Smart Card subsystem with independent SC1 and SC2 interfaces, each featuring dedicated reset, clock, I/O, presence detection, and C4/C8 pins - all compliant with ISO/IEC 7816-3 and EMV 4.2/4.3 timing constraints. Its UART interface supports standard PC baud rates up to 115.2 kbps plus non-PC 3 Mbps mode, with register compatibility to 16450 architecture.
Control is handled by an enhanced 8051 microcontroller running at up to 9.6 MHz, accessing peripherals via SFR/XDATA space. The device includes hardware-enforced Smart Card deactivation on removal, internal ESD protection per JESD22-A114D/A115A, and programmable FIFO thresholds with byte-granularity for ATR handling - eliminating software real-time dependency during card exchange.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Smart Card bridge applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SEC1210-I/PV-UR2 | Same die, identical UART and dual Smart Card functionality; differs only in marking (UR2 vs URT) - confirmed pin-to-pin and firmware-compatible per Microchip Product Identification System | Identical use cases; UR2 variant used in same industrial reader designs where marking denotes final test configuration | Select SEC1210-I/PV-UR2 only if legacy BOM specifies that marking; URT and UR2 share identical electrical, thermal, and functional behavior |
| SEC1110-I/PV-URT | Single Smart Card slot only; no SC2 interface or associated pins (SC2_VCC, SC2_RST_N, etc.); UART interface otherwise identical | Suitable for cost-sensitive single-slot readers but cannot support dual-card workflows like simultaneous ID+credential validation | Choose SEC1110-I/PV-URT only when dual-slot capability is unnecessary; SEC1210-I/PV-URT provides full feature set with no layout change penalty |
Compared with SEC1210-I/PV-UR2, the SEC1210-I/PV-URT offers identical dual Smart Card performance and UART interface but with distinct traceability marking; versus SEC1110-I/PV-URT, it adds second Smart Card channel with independent power and protocol control - enabling true concurrent dual-card authentication without external multiplexing.

FAQ
What host interface does the SEC1210-I/PV-URT support?
The SEC1210-I/PV-URT supports UART host interface only - not USB. It operates at standard PC baud rates (9600–115200 bps) and a high-speed 3 Mbps mode. This is explicitly defined in the Product Identification System table of DS00001561E, where SEC1210/PV-URT is listed under "UART" host interface with two Smart Card slots.
Does the SEC1210-I/PV-URT support dual Smart Card operation simultaneously?
Yes, the SEC1210-I/PV-URT supports true concurrent dual Smart Card operation via independent SC1 and SC2 interfaces. Each slot has dedicated VCC, RST_N, CLK, IO, PRSNT_N, and C4/C8 pins - enabling simultaneous activation, power control, and protocol handling without shared resources or software arbitration.
What Smart Card voltage classes does the SEC1210-I/PV-URT support?
The SEC1210-I/PV-URT supports Class A (5.0V), Class B (3.0V), and Class C (1.8V) Smart Cards on both SC1 and SC2 slots. Voltage is programmable per slot via internal regulators; an internal 4.8V comparator disables Class A support if VDD5 falls below threshold - ensuring safe operation per ISO/IEC 7816-3.
Is the SEC1210-I/PV-URT pin-compatible with other SEC1210 variants?
Yes, SEC1210-I/PV-URT is pin-compatible with all SEC1210 variants in the 24-pin QFN package (e.g., SEC1210-I/PV-UR2, SEC1210-I/PV-URT), as confirmed by identical pin tables (DS00001561E Table 3-2) and shared package outline drawings. Differences are limited to marking and final test configuration - not pin function or layout.
What is the maximum Smart Card data rate supported by the SEC1210-I/PV-URT?
The SEC1210-I/PV-URT supports Smart Card data rates up to 826 Kbps via versatile ETU rate generation, as stated in the General Description and Feature Highlights of DS00001561E. This covers current and proposed ISO/IEC 7816 transmission speeds, with hardware timers enforcing EMV-defined timing constraints at all rates.
