Product details
Overview
The 73S8014R-IL/F2 from Teridian Semiconductor is a single smart card (ICC) interface IC optimized for Set-Top-Box and A/V conditional access systems, providing ISO 7816-3/EMV 4.0 compliance, 3V/5V card voltage support, true 130mA over-current detection, and integrated LDO regulator delivering up to 65mA card current.
For engineers reviewing the 73S8014R-IL/F2 datasheet, 73S8014R-IL/F2 pinout, 73S8014R-IL/F2 application, or 73S8014R-IL/F2 equivalent, this device serves as a cost-reduced, firmware-compatible alternative to 8024-type interfaces with simplified 20-pin SO packaging, programmable VDD fault threshold, and dual-clock source support (crystal or external).
Technical Context
The 73S8014R-IL/F2 implements an ISO 7816-3-compliant activation/deactivation sequencer controlled by CMDVCC, RSTIN, and 5V/#V inputs, with automated emergency deactivation triggered by VDD undervoltage (adjustable via VDDF_ADJ), card over-current (>130mA), or VCC fault. Its embedded LDO regulator accepts 4.75–5.5V on VPC and outputs regulated 3V or 5V on VCC based on 5V/#V logic level.
Card clock generation supports both internal crystal oscillator (XTALIN/XTALOUT, up to 27MHz input) and external clock source, with CLKDIV1/CLKDIV2 selecting divide-by-2, -4, -8, or -1 to deliver up to 20MHz CLK to the card. The OFF interrupt pin provides open-drain fault reporting (card presence, removal, VDD fault, over-current) to the host controller.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Output Voltage | Programmable 3V or 5V via 5V/#V pin; meets EMV 4.0 and ISO 7816-3 voltage requirements. |
| Max Card Current | 65mA continuous; supports full EMV 4.0 transient loads including 100mA/2μs pulses. |
| Over-Current Detection | True current-sense circuitry (not VCC drop-based); trips at 70–130mA, enabling reliable fault isolation. |
| Card Clock Frequency | Up to 20MHz output; derived from 27MHz max XTAL/external clock using configurable CLKDIV1/CLKDIV2 dividers. |
| VDD Fault Threshold | Default 2.4V nominal; externally adjustable via VDDF_ADJ pin to match host MCU operating voltage range. |
| ESD Protection | ±6kV HBM on card interface pins (I/O, RST, CLK, VCC, GND), ensuring robust field operation. |
| Operating Temperature | -40°C to +85°C ambient; validated for industrial STB and pay-TV equipment environments. |
Pinout & Package
73S8014R-IL/F2 is housed in a RoHS-compliant, lead-free 20-pin Small Outline Package (SO-20) with standard 0.3" body width and 0.050" pitch.
| 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 protocols. |

| CLK (Pin 17) | Card clock output | Delivers up to 20MHz clock with 0.3–0.5 V/ns slew rate; supports 3V/5V card voltage levels. |
| PRES (Pin 19) | Card presence sense input | Active-high detection with internal high-impedance pull-down; reports insertion/removal to host. |
| CMDVCC (Pin 6) | Activation command input | Negative-asserted control: low initiates ISO 7816-3 activation sequence and enables VCC regulator. |
| 5V/#V (Pin 7) | Card voltage selection | High = 5V VCC mode; low = 3V VCC mode; default-pulled high for 5V compatibility. |
| OFF (Pin 1) | Fault/interrupt output | Open-drain active-low signal indicating card presence (inactive) or fault (active during session). |
| VDDF_ADJ (Pin 12) | VDD fault threshold adjust | Connects external resistor network to set custom VDD undervoltage trip point (e.g., 2.7V for 3.3V MCU). |
Key Features
| Feature | Design Value |
|---|---|
| Firmware compatibility with 8024-type ICs | Enables drop-in replacement in existing 8024-based designs without firmware modification. |
| Integrated LDO regulator with dual-voltage output | Eliminates need for external 3V/5V regulators; reduces BOM count and PCB area in STB designs. |
| True card over-current detection | Prevents false deactivation from VCC droop; ensures reliable fault response under dynamic card load conditions. |

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-IL/F2 | 24-pin SO package; supports synchronous and asynchronous cards; higher pin count and broader feature set. | Required where synchronous card support (e.g., memory cards) or additional control signals are needed. | Select when full 8024 feature set is required; not pin-compatible with 73S8014R-IL/F2. |
| SLC8014A-IF | Pin-compatible 20-pin SO; identical firmware and register map; manufactured by Maxim Integrated post-Teridian acquisition. | No functional change; same STB/PPV use cases and qualification status. | Preferred for new designs requiring long-term supply continuity; direct second-source with identical behavior. |
Compared with the 73S8014R-IL/F2, the 73S8024RN-IL/F2 adds synchronous card support but increases board space and cost, while the SLC8014A-IF offers identical functionality with enhanced lifecycle assurance-making it the optimal drop-in alternative for production continuity.

Manufacturer
Teridian Semiconductor Corporation was a fabless analog/mixed-signal IC designer specializing in smart card, energy metering, and communication interface solutions before its acquisition by Maxim Integrated in 2010.
The 73S80xxR family-including the 73S8014R-IL/F2-was engineered specifically for cost-sensitive, high-volume conditional access systems requiring full ISO 7816-3 and EMV 4.0 compliance in minimal footprint.
FAQ
What is the primary function of the 73S8014R-IL/F2 in a smart card system?
The 73S8014R-IL/F2 serves as a dedicated smart card interface IC that manages all electrical aspects of ISO 7816-3-compliant card communication-including VCC regulation (3V/5V), clock generation (up to 20MHz), reset signaling, bidirectional I/O buffering, and fault-safe activation/deactivation sequencing. It replaces discrete regulator, level-shifter, and timing circuits with a single integrated solution optimized for STB and PPV applications.
Does the 73S8014R-IL/F2 support both 3V and 5V smart cards?
Yes, the 73S8014R-IL/F2 supports both 3V and 5V smart cards through the 5V/#V pin: logic high selects 5V VCC output, and logic low selects 3V. The internal LDO regulator delivers compliant voltage levels with ripple <350mV and supports peak currents up to 130mA, satisfying EMV 4.0 transient requirements for both voltage classes.
How does the 73S8014R-IL/F2 handle card over-current faults?
The 73S8014R-IL/F2 implements true current-sense over-current detection-not voltage-drop monitoring-triggering automatic deactivation when card current exceeds 70–130mA. This ensures reliable fault response independent of PCB trace resistance or supply droop, distinguishing it from non-Teridian 8024 ICs that rely on less accurate VCC monitoring.
Can the 73S8014R-IL/F2 generate the card clock internally?
Yes, the 73S8014R-IL/F2 includes an on-chip crystal oscillator driven by an external crystal (XTALIN/XTALOUT) or accepts an external clock signal up to 27MHz. CLKDIV1 and CLKDIV2 pins configure division ratios (÷1, ÷2, ÷4, ÷8) to produce a final card clock up to 20MHz, meeting ISO 7816-3 timing and duty-cycle (45–55%) requirements.
What is the purpose of the VDDF_ADJ pin on the 73S8014R-IL/F2?
The VDDF_ADJ pin allows external adjustment of the VDD undervoltage fault threshold-from the default 2.4V down to ~2.15V or up-using a resistor network. This enables precise coordination with the host MCU's operating voltage range (e.g., setting 2.7V trip for a 3.3V MCU), ensuring card deactivation occurs before host logic failure.
