16-pin smartcard interfaces ST8034T, ST8034AT demonstration
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.

Description UM1608 Difference between ST8034T and ST8034AT demonstration boards The ST8034T and ST8034AT demonstration boards are identical, the only difference is control of external clock frequency divider, i.e. the response to setting on the CLKDIV input pin, see Table Table 1. ST8034T and ST8034AT clock frequency selection... -
Page 5: Board Layout
UM1608 Board layout Board layout Layout recommendations The ST8034xx family of devices includes an LDO block to generate V supply voltage for the smartcard, which (in contrast to previous ST8024/8024L devices with a charge pump) does not generate any noise and therefore even the requirements for a printed circuit board layout and external component selection are not so strict (general PCB layout rules apply). -
