73S8014R-ILR/F2

Overview

The Teridian 73S8014R is a single smart card interface circuit designed for asynchronous ICC support. It provides full electrical compliance with ISO 7816-3 and EMV 4.0 specifications, supporting both 3V and 5V cards via an internal LDO regulator powered by VPC (4.75V to 5.5V). Digital interfacing operates on VDD (2.7V to 5.5V). The device features a maximum card current of 65mA, over-current detection up to 130mA, and a card clock frequency up to 20MHz. It includes a crystal oscillator or external clock input up to 27MHz, 6kV ESD protection on card pins, and is housed in a 20-pin SO package.

Feature Summary

• Firmware compatible with 8024-type devices for simplified system integration
• Integrated LDO regulator generates VCC from dedicated power supply input
• True hardware-based card over-current detection function
• Adjustable VDD voltage fault threshold for automated deactivation

Applications

• Set-Top-Box Conditional Access systems
• Pay-per-View applications
• General purpose smart card readers

Procurement Notes

Verify the specific suffix 'ILR/F2' against the manufacturer's official ordering information table to confirm exact packaging type and temperature grade. Confirm availability status as this component may be subject to discontinuation or limited production runs depending on the current manufacturing lifecycle stage.

Selection Notes

Select this component when firmware compatibility with existing 8024 designs is required while reducing pin count. Ensure the application supports single I/O asynchronous cards only. Verify that the host processor can provide the necessary digital control signals and that the available power supplies meet the specified VPC and VDD ranges.

Part Context

The 73S8014R is part of the Teridian 73S80xxR family, derived from the industry-standard 73S8024RN. It is optimized for Set-Top-Box and A/V Conditional Access applications where cost reduction and smaller form factors are prioritized. The device maintains electrical compliance with major smart card standards while simplifying the external component requirements.

Replacement Considerations

The datasheet indicates direct firmware compatibility with all 8024 ICs. Designers migrating from other 8024-type interfaces should verify pinout differences and ensure the target application does not require synchronous card support, which is excluded from this model's capabilities.

FAQ

How is the VDD fault threshold adjusted?

The VDD fault threshold can be adjusted using an external resistor network connected to the VDDF_ADJ pin. If left open, it defaults to approximately 2.33V.

What determines the card clock frequency?

The card clock frequency is determined by an external crystal connected to XTALIN/XTALOUT or an external clock signal, divided by ratios selected via CLKDIV1 and CLKDIV2 inputs.

How does the device handle card faults?

Emergency card deactivation is initiated automatically upon card extraction or detection of faults such as card over-current, VCC undervoltage, or VDD power supply faults.
