AT83C22OK103-RDTIM

Specialized Overview

The AT83C22OK103-RDTIM is a specialized smart card reader interface chipset designed for integration into USB keyboards. It combines a smart card interface compliant with ISO 7816 and EMV 2000 standards with a USB host interface supporting CCID protocols. The device operates within an industrial temperature range and utilizes a 64-pin VQFP package. It provides firmware functionality for both smart card and keyboard support, enabling hardware integrators to implement smart card reader capabilities without additional driver development.

Specialized Feature Summary

• Supports T=0, T=1, TWI, and multi-wire smart card protocols with automatic type detection
• Integrates USB 1.1/2.0 compliance with CCID support for simplified host connection
• Includes built-in firmware for keyboard matrix handling up to 160 keys
• Provides secure pin entry (SPE) and LED status indicator control

Specialized Applications

• Integration of smart card reader functionality into multimedia keyboards
• Home-banking and payment security tokens requiring secure PIN entry
• Access control systems utilizing smart card authentication
• Internet security applications involving PKI-tokens

Specialized Procurement Notes

Verify the specific firmware version indicated by the 'xxx' suffix in the part number before ordering, as this determines the functional configuration. Confirm that the RDTIM suffix corresponds to the tray packing format required for your assembly process. Ensure compatibility with the target operating system drivers provided in the design-in kit documentation.

Specialized Selection Notes

Select this component when a unified solution for both smart card interfacing and keyboard matrix scanning is required within a single chip. Consider the industrial temperature range suitability for the intended environment. Evaluate the need for WHQL and EMV certifications, which are pre-integrated into this chipset to accelerate product certification timelines compared to discrete solutions.

Specialized Part Context

This device belongs to the CardMan Smart@Key chipset family developed by Atmel Corporation. It is based on the AT83C5122 microcontroller architecture. The series is designed to facilitate rapid time-to-market for smart card enabled peripherals by providing precertified hardware and firmware solutions.

Specialized Replacement Considerations

The AT83C22OKxxx-RDRIM serves as a tape and reel alternative to the RDTIM tray variant. Both share identical electrical and functional specifications but differ only in packaging format for automated assembly processes.
