ESD PROTECTION
the ESD spikes voltages. To cope with the different ESD
voltages developed across these pins, the built in structures
have been designed to handle either 2 kV, when related to the
micro controller side, or 8 kV when connected with the
external contacts (HBM model). Practically, the CRD_RST,

CRD_PRES and CRD_PRES pins can sustain 8 kV. The
CRD_VCC pin has the same ESD protection and can source
up to 75 mA continuously, the absolute maximum current
being internally limited with a max at 150 mA. The
CRD_VCC current limit depends on V
