It enables the management of any type of smart card from any kind of host. Up to 4 AT83C26 can be connected in parallel thanks to the programmable TWI address. Its high efficiency DC/DC converters and low quiescent current in stand-by mode make it particularly suited to low power and portable applications. The reduced bill of material allows to lower significantly the system size...
