The LTC
1755/LTC1756 universal Smart Card interfaces
are fully compliant with ISO 7816-3 and EMV specifica-
tions. The parts provide the smallest and simplest inter-
face circuits between a host microcontroller and general
purpose Smart Cards.
An internal charge pump DC/DC converter delivers regu-
lated 3V or 5V to the Smart Card, while on-chip level
shifters allow connection to a low voltage controller. All
Smart Card contacts are rated for 10kV ESD, eliminating
the need for external ESD protection devices.
Input voltage may range from 2.7V to 6.0V, allowing direct
connection to a battery. Internal soft-start mitigates start-
up problems that may result when the input power is
provided by another regulator. Multiple devices may be
paralleled and connected to a single controller for multicard
applications.
Battery life is maximized by 60
A operating current and
1
A shutdown current. The narrow SSOP packages mini-
mize PCB area for compact portable systems.
