Layout recommendations

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).

possible to the appropriate pin of the ST8034 device and use sufficiently wide PCB tracks.

Make the data and clock lines as short as possible and use a ground plane.
