Product details
Overview
SEC1210T-I/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 USB-to-Smart Card reader systems requiring EMV 4.3 and PC/SC compliance.
For engineers reviewing the SEC1210T-I/PV-UR2 datasheet, SEC1210T-I/PV-UR2 pinout, SEC1210T-I/PV-UR2 application, or SEC1210T-I/PV-UR2 equivalent, key selection criteria include dual-card support, UART-only host interface, industrial temperature range (–40°C to +85°C), integrated Smart Card clock generation, and hardware-enforced deactivation sequences per ISO/IEC 7816-3.
Technical Context
The SEC1210T-I/PV-UR2 implements two independent ISO/IEC 7816-3 Smart Card interfaces with full T=0/T=1 protocol support, programmable ETU rates up to 826 Kbps, and dedicated 261-byte full-packet FIFOs per channel. Its UART subsystem supports standard PC baud rates (up to 115.2 kbps) and high-speed 3 Mbps operation.
Controlled by an enhanced 8051 microcontroller, the device features self-clocking internal oscillator (no external crystal), 5.0 V-tolerant I/O, and integrated Smart Card power management with over-current detection, automatic card removal deactivation, and hardware-guarded timing compliance for EMV guard/time-out/CWT timers.

FAQ
What host interface does the SEC1210T-I/PV-UR2 support?
The SEC1210T-I/PV-UR2 supports UART host interface only - it uses the SPI1_MISO/RXD, SPI1_MOSI/TXD, SPI1_CLK/CTS_OUT, and SPI1_CE/RTS_IN pins configured as UART signals. USB functionality is disabled in this variant, unlike the SEC1210/PV-UR1 (USB-only) or SEC1210/PV-UR3 (dual-interface) versions.
Does the SEC1210T-I/PV-UR2 support both T=0 and T=1 Smart Card protocols?
Yes, the SEC1210T-I/PV-UR2 fully supports both T=0 and T=1 protocols per ISO/IEC 7816-3 and EMV 4.3. It includes dedicated state machines for T=0 parsing, internal procedure byte filtering, and protocol timers (guard, timeout, CWT) to enforce timing compliance without CPU intervention.
How does the SEC1210T-I/PV-UR2 handle Smart Card power supply?
The SEC1210T-I/PV-UR2 provides independent 1.8V/3.0V/5.0V Smart Card power outputs (SC1_VCC and SC2_VCC) with integrated regulation, current limiting, and over-current sense interrupt. Hardware ensures compliant deactivation on card removal, and an internal 4.8V comparator disables Class A (5.0V) support if VDD5 falls below specification.
What is the operating temperature range for the SEC1210T-I/PV-UR2?
The SEC1210T-I/PV-UR2 is rated for industrial temperature operation from –40°C to +85°C, as confirmed by the "T-I" suffix in the part number and specified in DS00001561E. This qualifies it for deployment in uncontrolled environments such as outdoor kiosks, ATMs, and transportation gateways.
Can the SEC1210T-I/PV-UR2 be used with synchronous Smart Cards?
Yes, the SEC1210T-I/PV-UR2 supports synchronous Smart Cards using GPIO-controlled signaling. Section 1.2 of DS00001561E explicitly states "Synchronous card support using GPIOs controlled via registers in the Smart Card device," and pins like SC1_C4 and SC1_C8 are designated for proprietary or synchronous use per Table 5-1.
