16-pin smartcard interfaces ST8034T, ST8034AT demonstration

boards

Introduction

The purpose of this document is to describe, and provide information on, how to efficiently

use the ST8034T and ST8034AT smartcard interface demonstration boards.

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.
