Microchip Technology SEC1210T-I/PV-URT

Overview

SEC1210T-I/PV-URT from Microchip Technology is a dual Smart Card bridge IC with UART host interface, integrated 8051 core, OTP ROM (16 KB), RAM (1.5 KB), and dual ISO/IEC 7816-compliant Smart Card interfaces supporting T=0/T=1 protocols at up to 826 Kbps. It delivers secure, self-contained card power regulation (1.8V/3.0V/5.0V), hardware-managed activation/deactivation, and ESD-protected card I/O - deployed in EMV-certified dual-card readers and secure authentication terminals.

For engineers reviewing the SEC1210T-I/PV-URT datasheet, SEC1210T-I/PV-URT pinout, SEC1210T-I/PV-URT application, or SEC1210T-I/PV-URT equivalent, key selection criteria include UART host compatibility, dual Smart Card support with independent voltage regulation, EMV 4.3 timing compliance, FIFO depth (261 bytes per channel), and industrial temperature operation (–40°C to +85°C).

Technical Context

The SEC1210T-I/PV-URT implements two independent ISO/IEC 7816-3 Smart Card interfaces with dedicated SC1_VCC/SC2_VCC regulators, programmable clock frequency, and full EMV 4.2/4.3 protocol timer suite (Guard, CWT, Timeout). Each interface features a 261-byte full-packet FIFO, automatic half-duplex turnaround, and hardware-enforced deactivation on card removal.

It integrates an enhanced 8051 CPU (9.6 MHz max), 16 KB OTP ROM, 1.5 KB RAM, and UART interface supporting standard PC baud rates plus 3 Mbaud high-speed mode. The device operates from 3.6V–5.5V, includes 5.0V-tolerant I/O, internal oscillator (no crystal required), and JTAG debug capability.

Key Specifications

Pinout & Package

SEC1210T-I/PV-URT is housed in a 24-pin QFN package (4 mm × 4 mm, 0.5 mm pitch) with exposed thermal slug (VSS). All power and ground pins are explicitly defined; VDD5 supplies 5.0V input, VDD33 provides regulated 3.3V analog output requiring 1 µF decoupling.

FAQ

What host interface does the SEC1210T-I/PV-URT support?

The SEC1210T-I/PV-URT supports UART-only host connectivity - not USB. It implements a 16550-compatible UART interface with standard PC baud rates (9600–115200 bps) and a high-speed 3 Mbaud mode. This configuration is confirmed in the Product Identification System table of DS00001561E, where SEC1210/PV-URT is explicitly designated for UART host interface with one Smart Card port. The SEC1210T-I/PV-URT shares this UART-only architecture.

Does the SEC1210T-I/PV-URT support dual Smart Card operation?

Yes, the SEC1210T-I/PV-URT supports two independent Smart Card interfaces (SC1 and SC2), each with dedicated VCC, RST_N, CLK, IO, PRSNT_N, and C4/C8 pins. Pin Table 3-2 and Block Diagram Figure 2-2 confirm the 24-pin QFN package includes full SC2 signal routing. The SEC1210T-I/PV-URT implements full dual-port functionality including separate EMV timing engines and independent power regulation per card - unlike the single-port SEC1110 series.

What Smart Card standards and protocols does the SEC1210T-I/PV-URT comply with?

The SEC1210T-I/PV-URT is fully compliant with ISO/IEC 7816-3, EMV 4.2/4.3, ETSI TS 102 221, and PC/SC standards. It supports both T=0 and T=1 protocols with hardware-enforced timing (Guard, CWT, Timeout timers), automatic parity error recovery, and synchronous card support via GPIO. These capabilities are documented in the General Description and Feature Highlights sections of DS00001561E, applicable to the entire SEC1210 family including SEC1210T-I/PV-URT.

What is the maximum data rate supported by the SEC1210T-I/PV-URT Smart Card interfaces?

The SEC1210T-I/PV-URT supports Smart Card data rates up to 826 Kbps via versatile ETU rate generation, as stated in the Feature Highlights and Introduction sections of DS00001561E. This rate applies to both SC1 and SC2 interfaces and covers current and proposed ISO/IEC 7816 transmission speeds. The device achieves this through programmable clock dividers and optimized FIFO handling - no external components are needed to reach this maximum rate.

What power supply requirements does the SEC1210T-I/PV-URT have?

The SEC1210T-I/PV-URT requires a single 3.6V–5.5V supply on VDD5. It generates internal 3.3V (VDD33), 1.2V, and Smart Card voltages (1.8V/3.0V/5.0V) on-chip. An internal 4.8V comparator disables Class A (1.8V) card support if VDD5 falls below threshold. A 1 µF capacitor is required on both VDD5 and VDD33 per datasheet recommendations in Section 5.2. This single-supply architecture simplifies power design versus multi-rail alternatives.
