73S8014R-IL/F2

Overview

The 73S8014R is a single smart card interface circuit derived from the 73S8024RN, optimized for Set-Top-Box and A/V Conditional Access applications. It supports asynchronous cards with a maximum current of 65mA compliant with ISO 7816-3 and EMV 4.0. The device features an internal LDO regulator powered by VPC (4.75V to 5.5V) to generate VCC at 3V or 5V. Digital logic operates on VDD (2.7V to 5.5V). It includes a crystal oscillator supporting up to 27MHz input, generating a card clock up to 20MHz via selectable dividers. The IC provides true over-current detection up to 130mA and adjustable VDD fault thresholds.

Feature Summary

• Firmware compatible with standard 8024-type devices for simplified migration
• Integrated Low Drop-Out (LDO) regulator generates isolated card power supply
• Hardware-controlled automated deactivation upon detecting faults such as over-current or voltage drops
• Adjustable VDD fault threshold allows customized system controller voltage 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 channels due to potential availability constraints. Confirm package integrity and pin alignment prior to assembly. Review datasheet revisions for any updates to electrical characteristics or mechanical dimensions. Ensure environmental compliance documentation matches project requirements.

Selection Notes

Select this component when firmware compatibility with existing 8024 designs is required alongside reduced pin count. Verify that the host processor can support the digital I/O control bus and interrupt signals. Ensure the system design accommodates the specific VPC and VDD power supply rails and external crystal or clock source requirements.

Part Context

This part belongs to the Teridian 73S80xxR family of smart card interface circuits. It serves as a cost-reduction alternative to traditional multi-interface ICs by focusing exclusively on asynchronous card support. The device maintains electrical compliance with industry standards while simplifying system integration through embedded regulation and protection.

Replacement Considerations

Direct substitution requires verifying firmware compatibility with the target 8024 architecture. Pin-to-pin replacement is possible within the 20-SOP package family, but ensure the application does not require synchronous card support or higher current limits than the 65mA specification.
