CMOS design guidelines for any semiconductor require
that no pin be taken above DVDD or below DGND.
Violation of this guideline can result in a hard failure
(damage to the silicon inside the device) or a soft fail-
ure (unintentional modification of memory contents).
Voltage spikes above or below the device’s absolute
maximum ratings can potentially cause a devastating
IC latchup.
Microcontrollers commonly experience negative volt-
age spikes through either their power pins or general-
purpose I/O pins. Negative voltage spikes on power
pins are especially problematic as they directly couple
to the internal power buses. Devices such as keypads
can conduct electrostatic discharges directly into the
microcontroller and seriously damage the device.
System designers must protect components against
these transients that can corrupt system memory.
To reduce the possibility of coupling noise into the
microcontroller, the system should be designed with a
crystal or oscillator in a metal case that is grounded to
the digital plane. Doing so reduces the susceptibility of
the design to fast transient noise.
Because the MAXQ3180 is designed for use in systems
where high voltages are present, care must be taken to
route all signal paths, both analog and digital, as far
away as possible from the high-voltage components.
It is possible to construct more elaborate metering
designs using multiple MAXQ3180 devices. This can be
accomplished by using a single SPI bus to connect all
the MAXQ3180 devices together but using separate
slave select lines to individually select each MAXQ3180.

Designers must ensure they have the latest MAXQ3180
errata documents. Errata sheets contain deviations
from published specifications. A MAXQ3180 errata
sheet for any specific device revision is available at
