DESCRIPTION

The L6605 is an IC dedicated as intelligent inter-

face between different types of smart cards and

microprocessors. The internal architecture can be

shared in a power supply section and in a diag-

nostic parts.

The power supply section can deliver 5V/80mA to

grammed by means of the 3 serial input bit (see
