3.0V/3.3V Microprocessor
Supervisory Circuits
General Description
These microprocessor (µP) supervisory circuits reduce the
complexity and number of components required for pow-
er-supply monitoring and battery-control functions in µP
systems. They significantly improve system reliability and
accuracy compared to separate ICs or discrete components.
These devices are designed for use in systems powered
by 3.0V or 3.3V supplies. See the selector guide in the
back of this data sheet for similar devices designed for
5V systems. The suffixes denote different reset threshold
voltages: 3.075V (T), 2.925V (S), and 2.625V (R) (see the
Reset Threshold
section in the
Detailed Description).
All
these parts are available in 8-pin DIP and SO packages.

*Contact
factory for dice specifications.
**These
parts offer a choice of reset threshold voltage. Select
the letter corresponding to the desired nominal reset threshold
voltage (T = 3.075V, S = 2.925V, R = 2.625V) and insert it into
the blank to complete the part number.
Devices in PDIP and SO packages are available in both leaded
and lead(Pb)-free packaging. Specify lead free by adding the +
symbol at the end of the part number when ordering. Lead free
not available for CERDIP package.
Pin Configuration appears at end of data sheet.
