LTC1756
Smart Card Interface
February 2000
FEATURES
DESCRIPTIO
N
U
The LTC
1756 universal Smart Card interface is fully
compliant with ISO 7816-3 and EMV specifications. It
provides the smallest and simplest interface circuit be-
tween 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 an on-chip level
shifter allows a 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 5.5V, allowing direct
connection to a battery. Automatic DC/DC converter soft
start mitigates start-up problems that may result when the
input power is provided by another regulator.
Battery life is maximized by 75
μ
A operating current and
2
μ
A shutdown current. The 16-pin SSOP package mini-
mizes PCB area for compact portable systems.
