73S8014RT-ILR/F2

Overview

The 73S8014RT-ILR/F2 is a single smart card interface circuit derived from the 73S8024RN, optimized for asynchronous card support in Set-Top-Box and A/V Conditional Access applications. It complies with ISO 7816-3 and EMV 4.0 specifications, supporting 3V and 5V cards with a maximum current of 65mA. The device features an internal LDO regulator powered by VPC (4.75V to 5.5V) and digital logic powered by VDD (2.7V to 5.5V). It includes a true over-current detection function up to 130mA, adjustable VDD fault thresholds, and 6kV ESD protection on card interface pins. The IC operates within an ambient temperature range of -40°C to +85°C.

Feature Summary

• Firmware compatible with standard 8024-type devices for simplified system integration
• Integrated Low Drop-Out (LDO) regulator generates card voltage with low power dissipation
• True hardware-based over-current detection ensures automated deactivation upon faults
• Adjustable VDD voltage supervisor threshold allows customized system controller matching

Applications

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

Procurement Notes

Verify component authenticity through authorized Analog Devices or Maxim Integrated channels. Confirm package integrity and pin alignment against the 20-pin SO specification. Review datasheet revisions for any updates to electrical characteristics or ordering information prior to implementation.

Selection Notes

Select this component when firmware compatibility with existing 8024 designs is required alongside reduced pin count. Ensure the application supports single I/O asynchronous cards. Verify that the host processor can manage the digital control bus and interrupt signals defined in the datasheet.

Part Context

This part belongs to the Teridian 73S80xxR family of smart card interface circuits. It serves as a cost-reduction alternative to traditional 8024 ICs by optimizing pin usage while maintaining electrical compliance with industry standards for conditional access modules.

Replacement Considerations

Direct substitutes include other members of the 73S80xxR family such as the 73S8024RN, provided pinout and firmware compatibility requirements are met. Verify functional equivalence regarding clock generation and fault detection logic before substitution.
