Product details
Overview
SEC1210/PV-URT from Microchip Technology is a single-chip Smart Card bridge IC supporting UART host interface and one ISO/IEC 7816-compliant Smart Card interface. It integrates an enhanced 8051 core (9.6 MHz max), 16 KB OTP ROM, 1.5 KB RAM, and full T=0/T=1 protocol support up to 826 Kbps ETU rate. Designed for secure USB-to-Smart Card reader systems where UART connectivity is required.
For engineers reviewing the SEC1210/PV-URT datasheet, SEC1210/PV-URT pinout, SEC1210/PV-URT application, or SEC1210/PV-URT equivalent, key selection factors include UART-only host interface capability, dual-voltage Smart Card power regulation (1.8V/3.0V/5.0V), EMV 4.2/4.3 compliance, integrated FIFO (261 bytes), and hardware-enforced card deactivation on removal.
Technical Context
The SEC1210/PV-URT implements a dedicated Smart Card subsystem with programmable clock frequency, protocol timers (Guard, Timeout, CWT), and automatic parity error recovery for T=0. Its UART interface supports standard PC baud rates (up to 115.2 kbps) and non-PC 3 Mbps high-speed mode.
It uses an internal 48 MHz oscillator with no external crystal required, operates from 3.6V–5.5V supply, and provides 5.0V-tolerant I/O pins. The device includes hardware-managed Smart Card power control with over-current detection interrupt and Class A/B/C/AB card voltage switching via SC1_VCC.

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-UR2 | Supports two Smart Card interfaces (SC1 + SC2); identical UART host interface and memory configuration | Required for dual-card readers (e.g., banking terminals with primary + backup card slots) | Select SEC1210/PV-UR2 when simultaneous dual-card operation or redundancy is needed; SEC1210/PV-URT is optimal for cost-sensitive single-card designs. |
| SEC1110-A5-02 | USB-only host interface; single Smart Card interface; no UART or SPI peripherals | Suitable for PC-connected readers without MCU host; lacks UART register compatibility and boot ROM | Choose SEC1110-A5-02 for pure USB endpoint applications; SEC1210/PV-URT is necessary when UART host integration or firmware boot via UART is required. |
Compared with SEC1210/PV-UR2 and SEC1110-A5-02, the SEC1210/PV-URT uniquely balances UART host flexibility, single-card Smart Card performance, and EMV-compliant hardware timing - making it the optimal choice for embedded MCU-based readers where USB is not the primary host interface.

FAQ
What host interface does the SEC1210/PV-URT support?
The SEC1210/PV-URT supports UART host interface only - it does not implement USB functionality. This variant is specifically configured for UART-based host communication, with pins SPI1_MISO/RXD, SPI1_MOSI/TXD, SPI1_CLK/CTS_OUT, and SPI1_CE/RTS_IN mapped to UART functions. USB_DP and USB_DM pins remain unused in this configuration.
Does the SEC1210/PV-URT support dual Smart Card interfaces?
No, the SEC1210/PV-URT supports exactly one Smart Card interface (SC1). The SEC1210 family includes variants like SEC1210/PV-UR2 that support two Smart Card interfaces, but SEC1210/PV-URT is explicitly designated for single-card applications per Microchip's Product Identification System documentation.
What Smart Card voltage classes does the SEC1210/PV-URT support?
The SEC1210/PV-URT supports Class A (5.0V), Class B (3.0V), and Class C (1.8V) Smart Cards via its SC1_VCC pin, which is programmable to output 1.8V, 3.0V, or 5.0V. An internal 4.8V comparator disables Class A support if VDD5 falls below 4.8V, ensuring safe operation per ISO/IEC 7816-3.
Is an external crystal required for SEC1210/PV-URT operation?
No, the SEC1210/PV-URT uses a self-clocking internal oscillator generating a stable 48 MHz clock - no external crystal or resonator is required. This reduces bill-of-materials cost and PCB footprint while maintaining timing accuracy sufficient for ISO/IEC 7816 and EMV timing constraints.
What is the maximum ETU data rate supported by SEC1210/PV-URT?
The SEC1210/PV-URT supports ETU rates up to 826 Kbps, covering all current and proposed ISO/IEC 7816 transmission speeds. This capability is implemented in hardware and verified per DS00001561E, enabling high-throughput Smart Card transactions without CPU overhead.
