DESCRIPTION (CONTINUED)

The LMP92018 also includes a 12-bit GPIO port which allows for the resources of the microcontroller to be

further extended, thus providing even more flexibility and reducing the number of signal interfacing to the

microcontroller.

Both the GPIO port and the SPI compatible interface have independent supply pins enabling the LMP92018 to

interface with low voltage microcontrollers.

The LMP92018 is available in a space saving 36-pin WQFN package and is specified over the full -30°C to

+85°C temperature range.
