Description

The ST8034T/ST8034AT/ST8034P/ST8034C devices are complete low-cost analog

interfaces for asynchronous and synchronous smartcards operating at a supply voltage

of 5 V or 3 V (or even 1.8 V in the case of ST8034P).

The ST8034T/ST8034AT/ST8034P/ST8034C devices can be placed between the card and

the microcontroller to provide all supply, protection, detection and control functions, with just

a few external components.
