Product details
Overview
SEC1210T/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 on-chip Smart Card power regulation for 1.8V/3.0V/5.0V cards. It enables secure USB-to-Smart Card reader designs where UART connectivity is required.
For engineers reviewing the SEC1210T/PV-URT datasheet, SEC1210T/PV-URT pinout, SEC1210T/PV-URT application, or SEC1210T/PV-URT equivalent, key selection criteria include UART-based host interfacing, dual-voltage Smart Card support, EMV 4.2/4.3 timing compliance, integrated FIFO (261 bytes), and hardware-managed card deactivation sequences.
Technical Context
The SEC1210T/PV-URT implements a dedicated Smart Card subsystem with full T=0/T=1 protocol support, programmable ETU rate generation up to 826 Kbps, and three EMV-defined protocol timers (Guard, Timeout, CWT). Its UART interface supports standard PC baud rates (up to 115.2 kbps) and non-PC high-speed mode (3 Mbps).
It features a self-clocking internal oscillator (no external crystal required), 3.6V–5.5V supply range, and 5.0V-tolerant I/O pins. Smart Card power is internally regulated and switched, with over-current detection and hardware-enforced deactivation on card removal - independent of software execution state.
Key Specifications

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 | Same die, two Smart Card interfaces instead of one - shares identical UART host interface and memory map | Supports dual-card operation (e.g., primary + backup, or dual-application cards) - not suitable for single-slot designs | Select SEC1210/PV-UR2 only when hardware layout accommodates second Smart Card connector and firmware requires concurrent dual-interface control. |
| AC102-2000 | Discrete Smart Card interface IC with UART host interface - lacks integrated 8051 core, OTP ROM, and EMV protocol timers | Requires external microcontroller for ATR parsing, T=0/T=1 state machines, and EMV timing enforcement - increases firmware complexity and BOM | Choose AC102-2000 only when design mandates separation of Smart Card PHY and protocol processing across multiple chips. |
Compared with SEC1210/PV-UR2, SEC1210T/PV-URT reduces pin count and PCB footprint by omitting second Smart Card interface while retaining identical UART performance and EMV compliance. Compared with AC102-2000, SEC1210T/PV-URT delivers full protocol offload - eliminating external MCU dependency for timing-critical Smart Card operations.

FAQ
What host interface does SEC1210T/PV-URT support?
SEC1210T/PV-URT supports UART-only host interface, configured via SPI1_MISO/RXD, SPI1_MOSI/TXD, SPI1_CLK/CTS_OUT, and SPI1_CE/RTS_IN pins. Unlike USB-enabled variants, it does not implement USB PHY or endpoint buffers - making it ideal for systems with existing UART infrastructure and no USB connectivity requirement.
How many Smart Card interfaces does SEC1210T/PV-URT provide?
SEC1210T/PV-URT provides exactly one ISO/IEC 7816-compliant Smart Card interface (SC1), with dedicated SC1_VCC, SC1_RST_N, SC1_CLK, SC1_IO, SC1_C4, SC1_C8, and SC1_PRSNT_N pins. It does not support a second Smart Card interface - that capability is exclusive to SEC1210/PV-UR2 and SEC1210-CN-02 variants.
Does SEC1210T/PV-URT include an integrated microcontroller?
Yes, SEC1210T/PV-URT integrates an enhanced 8051 microcontroller core running at up to 9.6 MHz, with 16 KB of OTP ROM for firmware storage and 1.5 KB of RAM for runtime data. This enables full Smart Card protocol stack execution - including T=0/T=1 state machines, EMV timer management, and ATR parsing - without requiring an external host processor.
What Smart Card voltage classes does SEC1210T/PV-URT support?
SEC1210T/PV-URT supports Class A (5.0V), Class B (3.0V), and Class C (1.8V) Smart Cards through its programmable SC1_VCC output. The internal regulator automatically selects the appropriate voltage based on card detection and protocol negotiation - and disables Class A support if VDD5 falls below 4.8V, as verified by the internal comparator.
Is SEC1210T/PV-URT qualified for industrial temperature operation?
Yes, SEC1210T/PV-URT is specified for industrial temperature range operation from –40°C to +85°C. This qualification applies to the full functional set - including Smart Card interface timing, UART communication, OTP ROM read reliability, and internal regulator stability - making it suitable for deployment in uncontrolled environmental conditions typical of access control panels and outdoor kiosks.
