AT83C25OK100-RDTIM

Specialized Overview

The AT83C25OK-RDTIM is a specialized smart card interface controller designed for PCMCIA host integration. It operates within an industrial temperature range and utilizes a VQFP64 package. The device supports ISO 7816 and EMV 2000 standards, enabling compatibility with T=0, T=1, TWI (S=8), SLE 4432/42 (S=10), and SLE4418/28 (S=9) protocols. It accommodates 5V, 3V, and 1.8V smart cards and provides up to 60 mA of supply current for card power. The component includes built-in short-circuit and thermal protection mechanisms alongside automatic smart card type detection.

Specialized Feature Summary

• Compliant with ISO 7816 and EMV 2000 standards for secure payment and access control applications
• Supports multiple communication protocols including T=0, T=1, TWI, and specific SLE series interfaces
• Integrated PCMCIA host interface facilitating direct connection to notebook or PC-Bus systems
• Includes hardware protections such as short-circuit prevention and thermal shutdown

Specialized Applications

• PCMCIA-based smart card readers for notebooks and portable computers
• Home-banking and financial transaction terminals
• Access control and identity authentication systems
• PKI tokens and health care identification devices

Specialized Procurement Notes

Verify the specific firmware version indicated by the 'xxx' suffix in the part number before procurement, as this determines the operational logic. Confirm that the VQFP64 tray packaging aligns with assembly requirements. Ensure the target system supports the required PCMCIA interface specifications and voltage levels compatible with the controller's operation.

Specialized Selection Notes

Select this component when designing embedded smart card solutions requiring pre-certified compliance with EMV 2000 and ISO 7816 standards. It is suitable for developers seeking to reduce time-to-market by utilizing a ready-to-use chipset rather than developing custom interface logic from scratch. Consider the industrial temperature range if the deployment environment involves variable conditions.

Specialized Part Context

This controller is part of the CardMan Smart@Bus chipset family developed by Atmel Corporation. It is based on the AT83C5122 microcontroller architecture. The product line is designed to facilitate rapid integration of smart card functionality into PCMCIA hosts without extensive firmware development. Omnikey AG provides associated drivers and documentation for implementation.

Specialized Replacement Considerations

Consult official manufacturer documentation for verified substitute part numbers. Check for updated firmware revisions or alternative packages within the same product family.
