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
supply the card and VPP/50mA to write the mem-
ory inside the card; the VPP voltage can be pro-
grammed by means of the 3 serial input bit (see
TAB, 1).
