Product details
Overview
73S8014RT-IL/F2 from Teridian Semiconductor is a single smart card (ICC) interface IC compliant with ISO/IEC 7816-3 and EMV 4.0, supporting 3V/5V cards with up to 65mA VCC output current, integrated LDO regulator, and true over-current detection at 130mA fault threshold. It serves as the electrical bridge between host microcontrollers and contact-based smart cards in conditional access systems.
For engineers reviewing the 73S8014RT-IL/F2 datasheet, 73S8014RT-IL/F2 pinout, 73S8014RT-IL/F2 application, or 73S8014RT-IL/F2 equivalent, key selection criteria include its 20-pin SO package, VDDF_ADJ-adjustable VDD fault threshold, firmware compatibility with 8024-type devices, and support for asynchronous card protocols in Set-Top-Box and pay-per-view systems.
Technical Context
The 73S8014RT-IL/F2 implements an ISO 7816-3 activation/deactivation sequencer with automated hardware-triggered deactivation on VDD undervoltage, VCC overcurrent (>130mA), or card extraction. Its dual-power architecture separates digital logic (VDD: 2.7–5.5V) from card power supply (VPC: 4.75–5.5V), enabling independent regulation and noise isolation.
Card clock generation supports both external crystal (up to 27MHz XTALIN/XTALOUT) and host-supplied clock, with programmable division via CLKDIV1/CLKDIV2 pins to deliver precise 20MHz max CLK output. The OFF interrupt pin provides open-drain fault reporting with active-low signaling for card presence, overcurrent, or VDD/VCC faults.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Output | 3V or 5V selectable via 5V/#V pin; regulated by internal LDO with 65mA continuous capability per ISO/EMV. |
| Overcurrent Detection | True current-sense circuit triggers deactivation at ≥130mA - not voltage-drop based - ensuring reliable card protection. |
| Card Clock Max | 20MHz output to smart card; derived from 27MHz max input clock or crystal via configurable CLKDIV1/CLKDIV2 dividers. |
| VDD Fault Threshold | Adjustable from default 2.4V nominal using external resistor network on VDDF_ADJ pin for system-specific brown-out coordination. |
| ESD Protection | ±6kV HBM on card interface pins (I/O, RST, CLK, VCC, GND), meeting robust field deployment requirements. |
| Operating Temp | -40°C to +85°C ambient range, validated for industrial and consumer STB environments without derating. |
| Supply Current | 2.2–3.0mA (VDD=4.5–5.5V, VCC on); enables low-power standby modes in battery-backed or energy-sensitive readers. |
Pinout & Package
73S8014RT-IL/F2 is housed in a RoHS-compliant 20-pin Small Outline Package (SO-20) with standard 0.3" body width and 0.050" lead pitch, optimized for compact Set-Top-Box PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| I/O (Pin 14) | Smart card bidirectional data line | ISO 7816 I/O signal with 11kΩ internal pull-up to VCC; handles T=0/T=1 protocol framing and bit-level communication. |
| RST (Pin 15) | Card reset driver | Active-high output driving smart card RST pin; current-limited to 30mA for safe card initialization and recovery. |
| CLK (Pin 17) | Card clock generator | Provides precisely timed 20MHz max clock to card; slew rate controlled (0.3–0.5 V/ns) to meet ISO edge-rate compliance. |
| PRES (Pin 19) | Card presence sense input | Active-high digital input with internal high-impedance pull-down; detects mechanical insertion/removal of smart card. |
| CMDVCC (Pin 6) | Activation control input | Negative-asserted command initiating ISO 7816-3 activation sequence and enabling VCC LDO output when low. |
| OFF (Pin 1) | Fault/interrupt output | Open-drain active-low interrupt signaling card presence (idle) or fault (active session), requiring external VDD pull-up. |
| VDDF_ADJ (Pin 12) | VDD fault threshold adjust | Analog input accepting external resistor network to set custom VDD brown-out voltage (e.g., 2.7V) for coordinated system shutdown. |
Key Features
| Feature | Design Value |
|---|---|
| Firmware compatibility | Binary-compatible register map and control logic with legacy 8024-type ICs, enabling drop-in replacement without host firmware changes. |
| True overcurrent detection | Dedicated current-sense circuitry (not VCC droop monitoring) ensures accurate 130mA fault triggering independent of load impedance. |
| Configurable VDD supervision | VDDF_ADJ pin allows precise tuning of fault threshold to match host MCU operating voltage window (e.g., 2.7V for 3.3V systems). |
| Low-component count | Integrated LDO, oscillator, sequencer, and level-shifters eliminate ≥6 external components versus discrete solutions. |
| EMV 4.0 compliance | Validated for payment terminal use with full support for 3V/5V card switching, transient current handling, and ESD robustness. |

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 SO package; supports synchronous & asynchronous cards; higher pin count adds flexibility but increases board area. | Required where synchronous card support (e.g., memory cards) or additional control signals are needed beyond 73S8014RT-IL/F2 scope. | Select 73S8024RN only if synchronous mode or extra I/O lines are mandatory; otherwise 73S8014RT-IL/F2 offers lower cost and smaller footprint. |
| SLB9670 | Trusted Platform Module (TPM) with integrated crypto engine; not a pure interface IC - lacks direct ISO 7816 physical layer functions. | Used for secure boot and platform attestation, not for general-purpose smart card reader applications requiring direct ICC interfacing. | SLB9670 is not a functional alternative; it serves a different security architecture layer and cannot replace 73S8014RT-IL/F2 in card reader designs. |
Compared with 73S8024RN, the 73S8014RT-IL/F2 delivers identical ISO/EMV compliance and firmware compatibility in a reduced 20-pin SO package optimized for cost-sensitive STB deployments, while SLB9670 addresses entirely distinct TPM use cases and cannot substitute for smart card interface functionality.

FAQ
What is the maximum card clock frequency supported by the 73S8014RT-IL/F2?
The 73S8014RT-IL/F2 supports a maximum card clock frequency of 20MHz, delivered to the smart card's CLK pin. This is achieved by dividing down a 27MHz maximum input clock (from XTALIN or external source) using the CLKDIV1 and CLKDIV2 control pins. The device enforces strict duty cycle (45–55%) and slew rate (0.3–0.5 V/ns) compliance to meet ISO/IEC 7816-3 timing requirements.
Does the 73S8014RT-IL/F2 support both 3V and 5V smart cards?
Yes, the 73S8014RT-IL/F2 supports both 3V and 5V smart cards through its programmable LDO regulator. The 5V/#V pin selects the output voltage: logic high configures VCC for 5V operation (4.65–5.25V), and logic low sets it for 3V (2.85–3.15V). This selection is electrically isolated from the activation sequence and must remain stable during CMDVCC assertion.
How does the overcurrent protection work in the 73S8014RT-IL/F2?
The 73S8014RT-IL/F2 implements true current-sense overcurrent protection - not voltage-drop detection - triggering automatic card deactivation when VCC load exceeds 130mA. This circuit operates independently of VCC ripple or ESR effects, providing deterministic fault response aligned with EMV 4.0 safety requirements and distinguishing it from non-Teridian 8024 ICs that rely on indirect VCC monitoring.
Can the VDD fault threshold be customized on the 73S8014RT-IL/F2?
Yes, the VDD fault threshold is adjustable via the VDDF_ADJ pin. By connecting an external resistor network (e.g., R1 to ground and R3 to VDD), designers can set a custom brown-out voltage - such as 2.7V for 3.3V host systems - using the formula Kx = (2.789/VTH) − 0.6125. Leaving VDDF_ADJ unconnected defaults to 2.4V nominal, matching typical 5V system margins.
Is the 73S8014RT-IL/F2 pin-compatible with other Teridian smart card ICs?
The 73S8014RT-IL/F2 shares firmware compatibility and functional equivalence with 8024-type devices like the 73S8024RN but is not pin-compatible due to its optimized 20-pin SO package versus the 24-pin layout of the 73S8024RN. Pin assignments differ significantly - e.g., no dedicated XTALOUT in 73S8014RT-IL/F2 - requiring PCB redesign for migration, though software integration remains unchanged.
