73S8014RN-ILR/F1

Overview

The Analog Devices Inc./Maxim Integrated 73S8014RN-ILR/F1 is a single smart card interface circuit designed for asynchronous ICC support. It provides full electrical compliance with ISO 7816-3, EMV 4.0, and NDS specifications. The device features an embedded LDO regulator generating 3V or 5V at up to 65mA from a dedicated VPC supply (4.75V–5.5V). Digital logic operates on a separate VDD supply ranging from 2.7V to 5.5V. It supports clock frequencies up to 20MHz via an internal oscillator or external input up to 27MHz. The component includes true over-current detection up to 130mA and offers 6kV ESD protection on the card interface.

Feature Summary

• Firmware compatible with 8024-type devices for simplified system integration
• Integrated LDO regulator reduces external component count and power dissipation
• True current-based over-current detection for enhanced fault protection
• Adjustable VDD voltage supervisor threshold for customized deactivation

Applications

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

Procurement Notes

Verify the specific suffix ILR/F1 against the manufacturer's official documentation to confirm package type and environmental rating. Confirm availability status as legacy components may have limited distribution channels. Ensure the host system design accommodates the required VPC and VDD power supply sequencing before procurement.

Selection Notes

Select this component when firmware compatibility with existing 8024 designs is required while reducing pin count. Verify that the application supports single I/O asynchronous cards only. Ensure the system controller can manage the digital inputs for activation and voltage selection. Confirm that the 20-pin SO package fits the target PCB layout constraints.

Part Context

This part belongs to the Teridian 73S80xxR family of smart card interfaces, now under Analog Devices/Maxim Integrated. It serves as a cost-reduction alternative to the 73S8024RN by optimizing the pinout for single-card applications. The device maintains electrical compatibility with industry standards while simplifying the interface to the host processor.

Replacement Considerations

The datasheet identifies the 73S8024RN as the primary reference device. The 73S8014RN is described as a smaller pin-count variant derived from the 73S8024RN. No other specific substitute part numbers are documented in the provided source material.
