Introduction
This document explains the functioning of the temperature sensor evaluation board which
consists of the ST72F651 microcontroller, STLM75 and STDS75 as temperature
and NAND Flash.
This board can operate in 2 modes:
■
Standalone / external power mode
■
USB powered mode
The configuration and operation of the evaluation board in both modes is explained in
different sections.
To select the desired mode, there is a power selection switch (S1) on the board which
enables the appropriate selection.
When this evaluation board is connected to the computer through a USB cable it also
functions as a mass storage device. The default state of the evaluation board is mass
storage mode. It switches over to temperature sensor mode using GUI.
