description

In addition, the LTC™1755/LTC1756 universal smart card interface is fully compliant with ISO 7816 and EMV specifications. The section provides the smallest and simplest interface circuitry between the host microcontroller and the general-purpose smart card.

An internal charge-pumped DC/DC converter provides a regulated 3V smart card or 5V, while an on-chip level converter allows connection to a low-voltage controller. All smart card contacts are rated for 10kV ESD, eliminating the need for external ESD protection devices.

The input voltage range can be from 2.7V to 6.0V and can be connected directly to the battery. Internal soft start mitigates start-up problems and may cause input power to be provided by another regulator. Multiple devices can be connected in parallel and connected to a single-controller, multi-card application.

Battery life is a maximum of 60μA operating current and 1μA shutdown current. Narrow SSOP package minimizes printed circuit board footprint Portable system.
