Product details
Overview
SEC1210T/PV-UR2 from Microchip Technology is a dual 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). It enables secure USB-to-Smart Card reader designs with EMV 4.2/4.3 and PC/SC compliance.
For engineers reviewing the SEC1210T/PV-UR2 datasheet, SEC1210T/PV-UR2 pinout, SEC1210T/PV-UR2 application, or SEC1210T/PV-UR2 equivalent, key selection criteria include dual-card support, UART-only host interface, embedded Smart Card protocol timers (CWT/Guard/Timeout), full-packet 261-byte FIFO per interface, and Class A/B/C voltage auto-detection without external regulators.
Technical Context
The SEC1210T/PV-UR2 implements two independent ISO/IEC 7816 interfaces with hardware-managed activation/deactivation sequences, cold/warm reset handling, and synchronous card support via GPIO-controlled timing. Each interface includes dedicated protocol timers (Guard, Timeout, CWT) enforcing EMV-defined timing constraints and automatic parity error recovery for T=0 protocol.
Its UART subsystem supports standard PC baud rates (9600–115200) and high-speed 3 Mbaud operation, while the 8051 core accesses peripherals exclusively through SFR/XDATA space. The device uses a self-clocking internal oscillator-no external crystal required-and features 5.0 V-tolerant I/O pins with integrated ESD protection per JESD22-A114D on all Smart Card pins.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Host Interface | UART only - no USB interface enabled; supports 3 Mbaud non-PC-standard rate for high-throughput Smart Card data transfer. |
| Smart Card Interfaces | Two independent ISO/IEC 7816 slots (SC1 & SC2) - each supports T=0/T=1 protocols, Class A/B/C cards (1.8V/3.0V/5.0V), and hardware-enforced deactivation on card removal. |
| FIFO Depth | 261 bytes per interface - full-packet buffering eliminates software real-time constraints during transmit/receive exchange. |
| Processor Core | Enhanced 8051 - 9.6 MHz max clock, ~9× instruction speed vs. legacy 80C51, with three 16-bit timers and JTAG debug support. |
| Memory | 16 KB OTP ROM + 1.5 KB RAM - firmware storage and runtime data handling without external memory; boot ROM included. |
| Supply Range | 3.6 V to 5.5 V - internal 4.8 V comparator disables Class A (5.0 V) card support if input voltage drops below safe threshold. |
| Operating Temperature | −40°C to +85°C - industrial-grade qualification ensures reliability in embedded terminal and kiosk environments. |
Pinout & Package
SEC1210T/PV-UR2 is housed in a 24-pin QFN package (4 mm × 4 mm, 0.5 mm pitch) with exposed thermal slug (VSS). All Smart Card pins (SCx_VCC, SCx_RST_N, SCx_CLK, SCx_IO, SCx_PRSNT_N, SCx_C4, SCx_C8) are electrically isolated and ESD-hardened. UART/SPI multiplexed pins are configured at reset based on strap options.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SC1_VCC / SC2_VCC | Smart Card Power Output | Programmable 1.8V/3.0V/5.0V supply per slot - regulated internally; requires 1 µF decoupling capacitor per pin. |
| SC1_RST_N / SC2_RST_N | Active-Low Card Reset | Hardware-triggered cold/warm reset pulse; asserts ATR generation; configurable as GPIO2/GPIO18. |
| SC1_CLK / SC2_CLK | Smart Card Clock Output | Programmable ETU rate generator up to 826 Kbps; configurable as GPIO1/GPIO17. |

| SC1_PRSNT_N / SC2_PRSNT_N | Card Presence Detection | Active-low input with software-controllable internal pull-up; triggers hardware deactivation on removal; configurable as JTAG_TMS/JTAG_TDI. |
| SPI1_MISO/RXD | UART Receive Input | Primary RXD pin when UART mode selected; weak internal pull-down prevents floating; configurable as GPIO8. |
| SPI1_MOSI/TXD | UART Transmit Output | Primary TXD pin when UART mode selected; drives logic-high output; configurable as GPIO9. |
| VDD5 | Main Supply Input | Accepts 3.6–5.5 V; powers Smart Card regulators and core logic; internal comparator monitors for Class A disable. |
| VDD33 | Analog Power Output | 3.3 V regulated analog supply for internal circuitry; requires external 1 µF capacitor. |
| RESET_N | System Reset Input | Active-low asynchronous reset; ≥1 µs pulse width required; enters STOP mode when asserted. |
Key Features
| Feature | Design Value |
|---|---|
| Dual Smart Card Support | Independent control of two ISO/IEC 7816 interfaces with separate FIFOs, clocks, and power domains - enables simultaneous card authentication in POS terminals. |
| EMV Timing Compliance | Hardware-implemented Guard, Timeout, and CWT timers enforce all EMV 4.2/4.3 timing constraints - eliminates software timing drift risk in payment applications. |
| Automatic Card Deactivation | Hardware-driven deactivation sequence triggered by SCx_PRSNT_N edge - guarantees compliant power-down regardless of CPU state or software latency. |
| Class Voltage Auto-Detection | Internal regulator selects 1.8V/3.0V/5.0V output based on card class detection - no external level-shifting or manual configuration needed. |
| UART High-Speed Mode | 3 Mbaud operation enables sub-100 ms ATR response and fast APDU exchange - critical for low-latency biometric or multi-application card workflows. |
| Self-Clocking Architecture | No external crystal or oscillator required - reduces BOM count and PCB footprint while maintaining ±1% clock accuracy for Smart Card timing. |

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/PV-UR1 | Same dual Smart Card + UART functionality but lacks SPI1 interface; pin-compatible QFN-24 package. | Targeted for cost-sensitive readers where SPI host connectivity is unnecessary. | Select SEC1210/PV-UR1 only if SPI1 signals are unused and BOM reduction is prioritized over future interface flexibility. |
| SEC1210T/PV-UR3 | Identical dual Smart Card + UART architecture but qualified for extended temperature range (−40°C to +105°C); same pinout and firmware compatibility. | Required for automotive infotainment or outdoor kiosk deployments exceeding +85°C ambient. | Choose SEC1210T/PV-UR3 when operating environment exceeds industrial grade limits; no design changes needed beyond thermal validation. |
Compared with SEC1210T/PV-UR2, SEC1210/PV-UR1 removes SPI1 capability to reduce test cost, while SEC1210T/PV-UR3 extends temperature rating without altering UART or Smart Card behavior-making SEC1210T/PV-UR2 the optimal balance of feature set, qualification, and supply stability for industrial embedded readers.

FAQ
What host interface does the SEC1210T/PV-UR2 support?
The SEC1210T/PV-UR2 supports UART-only host communication, not USB. It implements a 16450-compatible UART with standard PC baud rates (9600–115200 bps) and high-speed 3 Mbaud operation. This configuration is fixed per the /PV-UR2 suffix and cannot be reconfigured to USB mode in hardware or firmware.
How many Smart Card interfaces does the SEC1210T/PV-UR2 provide?
The SEC1210T/PV-UR2 provides two fully independent ISO/IEC 7816 Smart Card interfaces (SC1 and SC2), each supporting T=0 and T=1 protocols, Class A/B/C voltage levels (1.8V/3.0V/5.0V), and hardware-managed activation/deactivation. This dual-slot capability is confirmed in the Product Identification System table and block diagram for SEC1210 variants.
Does the SEC1210T/PV-UR2 require an external crystal or oscillator?
No, the SEC1210T/PV-UR2 uses a self-clocking internal oscillator and requires no external crystal or oscillator. Its 48 MHz master clock is generated on-die, and all Smart Card timing-including ETU rate generation up to 826 Kbps-is derived from this source with hardware-calibrated accuracy.
What is the maximum Smart Card data rate supported by the SEC1210T/PV-UR2?
The SEC1210T/PV-UR2 supports Smart Card data rates up to 826 Kbps via programmable ETU rate generation. This value is explicitly stated in the General Description and Feature Highlights sections of DS00001561E, covering both current and proposed ISO/IEC 7816 transmission speeds.
Is the SEC1210T/PV-UR2 pin-compatible with other SEC1210 variants?
Yes, the SEC1210T/PV-UR2 shares the same 24-pin QFN package and pinout as all SEC1210 variants (e.g., SEC1210/PV-UR1, SEC1210T/PV-UR3). Pin assignments for SC1/SC2 interfaces, UART, RESET_N, VDD5, and VDD33 are identical across the family, enabling drop-in replacement where functional differences (e.g., SPI presence, temp grade) are acceptable.
