Product details
Overview
73S8014RT-ILR/F2 from Teridian Semiconductor is a single smart card (ICC) interface IC designed for ISO/IEC 7816-3 and EMV 4.0 compliant applications. It provides 3V/5V card voltage selection via internal LDO regulator, true over-current detection up to 130mA, and supports card clock frequencies up to 20MHz. Its primary role is electrical interface and power sequencing between host controller and asynchronous smart cards in Set-Top-Box conditional access systems.
For engineers reviewing the 73S8014RT-ILR/F2 datasheet, 73S8014RT-ILR/F2 pinout, 73S8014RT-ILR/F2 application, or 73S8014RT-ILR/F2 equivalent, key selection criteria include VDD fault threshold adjustability, 65mA continuous card current capability, 6kV ESD protection on card I/O pins, and firmware compatibility with legacy 8024-type interfaces.
Technical Context
The 73S8014RT-ILR/F2 implements an ISO 7816-3 activation/deactivation sequencer with hardware-triggered emergency deactivation on VCC over-current, VDD undervoltage, or card extraction. Its LDO regulator derives VCC from dedicated VPC supply (4.75–5.5V), while digital logic operates from separate VDD (2.7–5.5V).
Card clock generation supports either external crystal (XTALIN/XTALOUT) or host-supplied clock up to 27MHz, with programmable division (÷2, ÷4, ÷8, ÷1) via CLKDIV1/CLKDIV2 inputs. The OFF interrupt output reports both card presence (high = no card) and fault conditions (low = VDD fault, over-current, or card removal during session).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Output Voltage | 3.0V or 5.0V selectable via 5V/#V pin; meets EMV 4.0 and ISO 7816-3 voltage tolerances. |
| Max Card Current | 65mA continuous (ISO/EMV-compliant); 130mA over-current fault threshold enables true current-sense protection. |
| Card Clock Frequency | Up to 20MHz output; derived from 27MHz max input clock or crystal oscillator with programmable division. |
| VDD Fault Threshold | Default 2.4V nominal; adjustable via external resistor network on VDDF_ADJ pin to match host MCU operating range. |
| ESD Protection | ±6kV HBM on card interface pins (I/O, RST, CLK, VCC, GND); ensures robustness in consumer STB environments. |
| Operating Temperature | −40°C to +85°C ambient; validated for industrial-grade Set-Top-Box deployment. |
| Supply Voltages | VPC: 4.75–5.5V (LDO input); VDD: 2.7–5.5V (digital logic); enables flexible system-level power architecture. |
Pinout & Package
73S8014RT-ILR/F2 is housed in a RoHS-compliant 20-pin SOIC (Small Outline Integrated Circuit) package with standard 0.3-inch body width and 0.050-inch lead pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| I/O (Pin 14) | Smart card bidirectional data line | Level-shifted to selected VCC (3V/5V); includes 11kΩ internal pull-up to VCC for ISO compliance. |
| RST (Pin 15) | Smart card reset output | Drives card RST with 30mA current limit; slew rate controlled per VCC voltage (0.3–0.5 V/ns). |
| CLK (Pin 17) | Smart card clock output | Delivers up to 20MHz clock; current-limited to 70mA; duty cycle maintained at 45–55%. |
| PRES (Pin 19) | Card presence sense input | Active-high signal with internal high-impedance pull-down; detects mechanical insertion/removal. |
| CMDVCC (Pin 6) | Card activation command input | Negative-asserted control: low initiates ISO 7816-3 activation sequence and ramps VCC. |
| OFF (Pin 1) | Interrupt output to host | Open-drain output with 20kΩ internal pull-up to VDD; signals card presence (high) or fault (low). |
| VDDF_ADJ (Pin 12) | VDD fault threshold adjustment | Allows external resistor network to set custom VDD undervoltage trip point for coordinated system shutdown. |
Key Features
| Feature | Design Value |
|---|---|
| True over-current detection | Hardware-based current sensing (not VCC drop detection) enables reliable card disconnection during fault without false triggers. |
| Firmware compatibility with 8024 ICs | Direct replacement for legacy 8024-family interfaces without host software modification. |
| Adjustable VDD fault threshold | External resistor network on VDDF_ADJ allows precise alignment with host MCU's brown-out detection level. |
| Integrated LDO regulator | Eliminates need for external 3V/5V regulators; reduces BOM count and improves noise immunity in STB designs. |
| 6kV ESD protection on card interface | Meets IEC 61000-4-2 Level 4 requirements for consumer electronics without external TVS diodes. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar smart card interface applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 73S8024RN | 24-pin SOIC; supports synchronous and asynchronous cards; higher pin count and broader feature set including auxiliary I/O. | Required where synchronous card support (e.g., memory cards) or additional control signals are needed. | Choose 73S8024RN only if synchronous card compatibility or extra GPIOs are mandatory-73S8014RT-ILR/F2 offers lower cost and smaller footprint for async-only use. |
| SLB9670 | Trusted Platform Module (TPM) with integrated smart card controller; not a standalone interface IC; requires different firmware stack. | Used in PC/laptop security subsystems-not suitable as direct replacement for embedded card readers. | Select SLB9670 only for TPM-integrated security architectures; 73S8014RT-ILR/F2 remains optimal for dedicated, low-cost smart card interface in STB and payment terminals. |
Compared with 73S8024RN and SLB9670, the 73S8014RT-ILR/F2 delivers targeted optimization for asynchronous smart card applications-offering smallest footprint, lowest BOM cost, and simplest integration while maintaining full ISO/EMV compliance and true over-current protection.

FAQ
What is the maximum continuous current the 73S8014RT-ILR/F2 can deliver to a smart card?
The 73S8014RT-ILR/F2 delivers up to 65mA continuous current to the smart card under ISO 7816-3 and EMV 4.0 specifications. This is achieved via its integrated LDO regulator powered from the VPC supply. The device also features a true over-current detection circuit with a 130mA fault threshold, ensuring safe deactivation during transient overload events without relying on VCC voltage drop monitoring.
Does the 73S8014RT-ILR/F2 support both 3V and 5V smart cards?
Yes, the 73S8014RT-ILR/F2 supports both 3V and 5V smart cards through the 5V/#V pin (Pin 7). When this pin is logic high, the internal LDO outputs 5.0V to VCC; when low, it outputs 3.0V. The LDO maintains tight regulation-2.85–3.15V for 3V mode and 4.65–5.25V for 5V mode-at loads up to 65mA, fully meeting EMV 4.0 voltage tolerance requirements.
How does the OFF pin on the 73S8014RT-ILR/F2 function in normal operation versus fault conditions?
The OFF pin (Pin 1) is an open-drain interrupt output with a 20kΩ internal pull-up to VDD. In normal operation with no card inserted, OFF is high. When a card is present and inactive, OFF remains high. During card activation (CMDVCC low), a low on OFF indicates a fault-such as VDD undervoltage, VCC over-current, or card removal. This dual-mode signaling simplifies host polling and eliminates need for separate presence and fault lines in the 73S8014RT-ILR/F2 design.
Can the 73S8014RT-ILR/F2 generate the smart card clock internally?
Yes, the 73S8014RT-ILR/F2 can generate the smart card clock internally using an external crystal connected to XTALIN (Pin 9) and XTALOUT (Pin 10). Alternatively, it accepts an external clock signal up to 27MHz on XTALIN. The CLK output (Pin 17) frequency is programmable via CLKDIV1 and CLKDIV2 pins to divide the source by 2, 4, 8, or 1, enabling precise 20MHz max CLK output required by ISO 7816-3.
Is the 73S8014RT-ILR/F2 pin-compatible with other devices in the Teridian 73S80xxR family?
The 73S8014RT-ILR/F2 uses a 20-pin SOIC package and is firmware-compatible with 8024-type ICs, but it is not pin-compatible with the 24-pin 73S8024RN due to differing pin count and assignment. Its pinout is optimized for reduced system complexity-omitting auxiliary signals present in larger variants-so PCB layout must be designed specifically for the 20-pin 73S8014RT-ILR/F2 footprint and signal mapping.
