IMPORTANT APPLICATION NOTE
The pins on the DS87C530/DS83C530 are generally as resilient as other CMOS circuits. They have no unusual sus-
ceptibility to electrostatic discharge (ESD) or other electrical transients.
However, no pin on the
DS87C530/DS83C530 should ever be taken to a voltage below ground.
Negative voltages on any pin can turn on
internal parasitic diodes that draw current directly from the battery. If a device pin is connected to the “outside world”
where it may be handled or come in contact with electrical noise, protection should be added to prevent the device pin
from going below -0.3V. Some power supplies can give a small undershoot on power up, which should be prevented.
Application Note 93, “Design Guidelines for Microcontrollers Incorporating NVRAM”, discusses how to protect the
DS87C530/DS83C530 against these conditions.
