ST92F120 - GENERAL DESCRIPTION
1.2.4.5 Power Supply and Ground
As already said for the I/O pins, in order to guaran-
tee ST9 compliancy with respect to Quality Assur-
ance recommendations concerning ESD and
Latchup, dedicated circuits are added to the differ-
ent power supply and ground pins (digital and an-
alog). These structures create preferred paths for
the high current injected during discharges, avoid-
ing damage to active logic and circuitry. It is impor-
tant for the system designer to take this added cir-
cuitry into account, which is not always transpar-
ent with respect to the relative level of voltages ap-
plied to the different power supply and ground
pins. Figure 6 shows schematically the protection
net implemented on ST9 devices, composed of di-
odes and other special structures.
The clamp structure between the VDD and VSS
pins is designed to be active during very fast tran-
sitions (typical of electrostatic discharges). Other
paths are implemented through diodes: they limit
the possibility of positively differentiating AVDD
and VDD (i.e. AVDD > VDD); similar considerations
are valid for AVSS and VSS due to the back-to-
back diode structure implemented between the
two pins. Anyway, it must be highlighted that, be-
cause VSS and AVSS are connected to the sub-
strate of the silicon die (even though in different ar-
eas of the die itself), they represent the reference
point from which all other voltages are measured,
and it is recommended to never differentiate AVSS
from VSS.
Note: If more than one pair of pins for VSS and
VDD is available on the device, they are connected
internally and the protection net diagram remains
the same as shown in Figure 6.
