16-pin smartcard interface ST8034C demonstration board
Introduction
The purpose of this document is to describe, and provide information on, how to efficiently
use the ST8034C smartcard interface device demonstration board.
The ST8034xx is a family of complete smartcard interface devices, compatible with ISO
7816, NDS and EMV™ 4.3 payment systems that provide selectable supply voltage for the
smartcard with automatic deactivation sequence in case of overload, short-circuit or
undervoltage, with programmable internal or external clock signal, reset signal and
protected I/O data lines. The ST8034HC and ST8034C product variants also provide a chip
select function that allows the device interface to be isolated from the microcontroller bus
signals and to share the bus among multiple card interface devices in a parallel
combination.
In summary, ST8034xx interface devices are placed between the smartcard and the
microcontroller to provide all supply, protection, detection and control functions, with just
minimum external components.
