AT83C23OK Description Smart Cards are increasingly being used for Payments, Home-Banking, Access Control,
Internet Security, PKItokens, Health Care, Loyalty, etc.
The CardMan Smart@Link chip set is a ready to use precertified smart card reader inter-
face, that can be implemented into USB hosts. It facilitates hardware integrators by
reducing time-to-market and offers a unique opportunity to quickly and easily include
smart card reader functionality in systems like PCs, Notebooks, Keyboards, Smart Card
based Dongles, Monitors, Mice, PDAs, Thin Clients, Biometric devices etc. The already
existing certifications and compliances guarantee a fast and easy certification process.
With its high performance Smart Card Interface CardMan Smart@Link supports smart-
card technology of the future.
The integration in any USB system can be easily done without any firmware or software
(driver) development, simply by embedding the CardMan Smart@Link design and
chipset into the target system. The USB CCID support makes this process the easiest
ever by connecting host and Smart Card Reader systems without the need of additional
drivers.
CardMan Smart@Link combines Atmel’s AT83C5123 microcontroller and Omnikey
firmware.
For detailed information on the Omnikey firmware, please refer to the Omnikey web site:
omnikey.aaitg.
In addition to the summary information contained in this document, please refer to the
AT83C5123 datasheet for complete product information. This document is available on
the Atmel web site www.atmel.

Reset Input
The Port pins are driven to their reset conditions when a voltage lower than V IL is applied, whether or not the oscillator is running.
This pin has an internal 10K pull-up resistor which allows the device to be reset by connecting a capacitor between this pin and VSS.
Asserting RST when the chip is in Idle mode or Power-Down mode returns the chip to normal operation.
The output is active for at least 12 oscillator periods when an internal reset occurs.D+
