LTC1755EGN General Description

The LTC1755/LTC1756 universal Smart Card interfaces are fully compliant with ISO 7816-3 and EMV specifications. The parts provide the smallest and simplest interface circuits between a host microcontroller and general purpose Smart Cards.An internal charge pump DC/DC converter delivers regulated 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.

Key Features

Fully ISO 7816-3 and EMV Compliant (Including Auxiliary I/O Pins)
Buck-Boost Charge Pump Generates 3V or 5V
2.7V to 6.0V Input Voltage Range (LTC1755)
Very Low Operating Current: 60μA
Dynamic Pull-Ups Deliver Fast Signal Rise Times
Soft-Start Limits Inrush Current at Turn On
3V ? 5V Signal Level Translators
Shutdown Current: <1μA
Short-Circuit and Overtemperature Protected
Alarm Output Indicates Fault Condition
Multiple Devices May Be Paralleled for Multicard Applications (LTC1755)
Available in 16- and 24-Pin SSOP Packages

Application

Battery life is maximized by 60μA operating current and 1μA shutdown current. The narrow SSOP packages minimize PCB area for compact portable systems.
Applications
Handheld Payment Terminals
Pay Telephones
Key Chain Readers
Smart Card Readers
