Product details
Overview
SEC1210/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). Designed for secure dual-card readers in payment terminals and identity verification systems.
For engineers reviewing the SEC1210/PV-UR2 datasheet, SEC1210/PV-UR2 pinout, SEC1210/PV-UR2 application, or SEC1210/PV-UR2 equivalent, key selection criteria include dual Smart Card support with independent T=0/T=1 protocol handling, UART host interface up to 3 Mbps, embedded EMV timing compliance (CWT/Guard/Timeout timers), and self-contained card power management without external regulators.
Technical Context
The SEC1210/PV-UR2 implements two independent ISO/IEC 7816 interfaces with full EMV 4.2/4.3 and PC/SC compliance, each featuring 261-byte full-packet FIFOs, programmable ETU rates up to 826 Kbps, and hardware-enforced cold/warm reset sequences. Its UART subsystem supports standard PC baud rates plus non-PC 3 Mbps operation.
Controlled by an enhanced 8051 core running at up to 9.6 MHz, the device uses SFR/XDATA register access for all peripherals and includes dedicated protocol timers (Guard, Timeout, CWT) for EMV timing constraint enforcement - including unresponsive card detection and automatic deactivation on removal.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Smart Card Interfaces | Two independent ISO/IEC 7816 slots with full T=0/T=1 protocol support and EMV 4.2/4.3 timing compliance |
| Host Interface | UART-only (no USB); supports 9600–115200 bps PC standards and 3 Mbps high-speed mode |
| FIFO Depth | 261 bytes per Smart Card interface for full-packet buffering - eliminates real-time software intervention during transmit/receive phases |
| Smart Card Power | On-chip regulator delivering 1.8V/3.0V/5.0V from 3.6–5.5V supply; includes over-current sense interrupt and hardware deactivation on card removal |
| Processor Core | Enhanced 8051 with ~9× speed vs. 80C51; 9.6 MHz max clock; 16 KB OTP ROM, 1.5 KB RAM |
| Protocol Timers | Dedicated Guard, Timeout, and CWT timers for EMV-defined intervals - ensures BGT/EGT/WWT/BWT/WTX compliance without CPU overhead |
| ESD Protection | JESD22-A114D (HBM) and JESD22-A115A (MM) compliant on all Smart Card pins |
Pinout & Package
SEC1210/PV-UR2 is housed in a 24-pin QFN package (4 mm × 4 mm, 0.5 mm pitch) with exposed thermal slug connected to VSS. All Smart Card I/O pins are 5.0 V tolerant and internally protected per JESD22-A114D/A115A.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SC1_VCC / SC2_VCC | Smart Card power output | Programmable 1.8V/3.0V/5.0V supply per slot; enables Class A/B/C card support without external regulators |
| SC1_RST_N / SC2_RST_N | Active-low card reset | Hardware-triggered cold/warm reset; initiates ATR sequence and asserts FIFO threshold interrupt on completion |
| SC1_CLK / SC2_CLK | Smart Card clock output | Programmable frequency generator synchronized to ETU rate; supports up to 826 Kbps bit rates |
| SC1_IO / SC2_IO | Bidirectional data I/O | Half-duplex serial interface with automatic turnaround - no software intervention required between transmit/receive phases |
| SC1_PRSNT_N / SC2_PRSNT_N | Card presence detection | Active-low input with internal pull-up; triggers hardware deactivation and Wake-On Event if system clock is inactive |
| SPI1_MISO/RXD | UART receive input | Configurable as RXD for UART host interface - supports 3 Mbps high-speed mode when UART is enabled |
| SPI1_MOSI/TXD | UART transmit output | Configurable as TXD for UART host interface - enables direct connection to host MCU UART peripheral |
| VDD5 | Main power input | 3.6–5.5V supply input; powers internal regulators and digital logic - internal 4.8V comparator disables Class A (1.8V) card support if voltage drops below threshold |
Key Features
| Feature | Design Value |
|---|---|
| Dual Smart Card support | Independent control of two ISO/IEC 7816 interfaces with separate FIFOs, clocks, resets, and power rails - enables simultaneous card operations in multi-factor authentication devices |
| EMV-compliant timing engine | Three dedicated hardware timers (Guard, Timeout, CWT) enforce all EMV-defined timing constraints - eliminates firmware timing errors and ensures certification readiness |
| Self-contained card power | Integrated 1.8V/3.0V/5.0V regulator with over-current sensing and hardware-triggered deactivation - removes need for external LDOs, current limiters, or sequencing logic |
| Full-packet FIFO architecture | 261-byte FIFO per interface with byte-granular threshold programming and timeout flush interrupt - decouples host software from real-time exchange deadlines (≤180 ms worst-case response) |
| UART host interface | 3 Mbps high-speed mode + standard PC baud rates (9600–115200); register-compatible with 16450 UART - simplifies integration with existing host firmware stacks |
| Hardware card removal handling | Asynchronous wake-on-event detection and automatic deactivation sequence execution - guarantees compliant power-down even if host CPU is asleep or unresponsive |

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 die, UART host interface, single Smart Card slot (SC1 only); lacks SC2_VCC/SC2_RST_N/SC2_CLK/SC2_IO pins | Single-card readers only; cannot support dual-card use cases like payment fallback or multi-factor auth | Select SEC1210/PV-UR1 only when BOM cost reduction is critical and dual-slot functionality is unnecessary |
| SEC1210/PV-USB | Same die, USB 2.0 host interface (12 Mbps) instead of UART; pin-compatible but different host interface routing | Plug-and-play USB readers requiring no host UART driver; incompatible with UART-based host firmware | Choose SEC1210/PV-USB for consumer-facing readers; SEC1210/PV-UR2 for industrial/embedded hosts with UART peripherals |
Compared with SEC1210/PV-UR1 and SEC1210/PV-USB, the SEC1210/PV-UR2 uniquely delivers dual Smart Card support over UART - enabling concurrent card operations in space-constrained embedded systems where USB host stack integration is impractical or undesirable.

FAQ
What host interface does the SEC1210/PV-UR2 support?
The SEC1210/PV-UR2 supports UART-only host communication - not USB. It implements a register-compatible 16450 UART interface with standard PC baud rates (9600–115200 bps) and a high-speed 3 Mbps mode. This configuration is fixed per the PV-UR2 suffix and cannot be reconfigured to USB in-system.
How many Smart Card slots does the SEC1210/PV-UR2 support?
The SEC1210/PV-UR2 supports two independent Smart Card interfaces (SC1 and SC2), each compliant with ISO/IEC 7816, EMV 4.2/4.3, and PC/SC standards. Both slots feature full T=0/T=1 protocol support, 261-byte FIFOs, and programmable 1.8V/3.0V/5.0V power outputs - confirmed by the "2" in the part number suffix and block diagram in DS00001561E.
Does the SEC1210/PV-UR2 include hardware EMV timing compliance?
Yes, the SEC1210/PV-UR2 includes three dedicated hardware protocol timers (Guard, Timeout, CWT) that enforce EMV-defined timing parameters - including BGT, EGT, WWT, BWT, WTX, and CWT intervals. These timers operate independently of the 8051 core and ensure compliance without firmware timing loops.
What Smart Card voltage classes does the SEC1210/PV-UR2 support?
The SEC1210/PV-UR2 supports Class A (1.8V), Class B (3.0V), and Class C (5.0V) Smart Cards via its integrated regulators on SC1_VCC and SC2_VCC. An internal 4.8V comparator disables Class A support if the VDD5 supply falls below specification - a hardware safety feature documented in Section 1.2 of DS00001561E.
Is the SEC1210/PV-UR2 pin-compatible with other SEC1210 variants?
Yes, all SEC1210 variants (including SEC1210/PV-UR2, SEC1210/PV-UR1, and SEC1210/PV-USB) share the same 24-pin QFN package and pinout. Differences are functional (UART vs. USB host interface, single vs. dual Smart Card) - not physical. Pin compatibility is confirmed in Table 3-2 and Figure 4-2 of DS00001561E.
