STEVAL-IFS012V1 demonstration board for
multiple temperature sensors
Introduction
This user manual explains the functions of the multi-device temperature sensor
demonstration board which is based on a motherboard and daughter card approach. The
complete system consists of the motherboard with an ST72F651 microcontroller and
daughter cards with temperature sensors. The temperature sensors supported by this
system are:
■STLM20
■STTS424E02
■STTS75
■STDS75
■STLM75
■STCN75
This board can operate in 2 modes:
■Standalone / external-power mode
■USB-powered mode / full-featured mode
The board's configuration and operation in both modes is explained in different sections. To
select the desired mode, there is a power selection switch (SW5) on the board which
enables the appropriate selection. When this board is connected to a computer through the
USB cable then it also behaves as a mass storage device. The default state of the board
(with USB connection) is mass storage mode. It switches to temperature-sensor mode using
a graphical user interface (GUI).

2 External power mode selection
To select the external supply mode position the switch (SW5) as shown in Figure 3. Then
plug in the DC adapter (8 V - 20 V,1 A and center positive) with a female connector to the
power jacket (J6) and the green colored LED (D8) turns on.

3 USB-powered mode selection
To select USB-powered mode unplug the external power supply and then position the power
switch, as shown in Figure 4. Then plug the USB cable into the USB socket (J2) on the
board. A red colored LED (D6) turns on and the board is powered up through USB-power.
Figure 4. Power selection switch (SW5) to select for USB-power
Note: At any time only one power supply should be plugged in (either USB or external power
adapter). The power LED (green (D8) for external supply and red (D6) for USB supply) turns
on as soon as the power is plugged in but the power is connected to the board only by
appropriate switch settings as shown in Figure 3 and Figure 4.

External power mode of board UM0690
10/39 Doc ID 15482 Rev 1
4 External power mode of board
This mode is also called the standalone mode of board. In this mode the board is supplied
by an external power supply and continuously displays the time and temperature on the
LCD. A computer interface is not needed for this mode.
4.1 Powering of the board
The motherboard can be powered to 5 V using an external supply or a USB supply whereas
daughter cards can be powered to one of 1.8 V/2.5 V/3.3 V/5.0 V using the J16 and JP1
jumpers on the motherboard.
The procedure for powering the board is explained below.
●Steps:
– Select the power selection switch (SW5) as external power mode as explained in
Figure 3
– Place the jumper on J16
– To supply the temperature-sensor daughter card with 5 V, place the jumper on pin
1 and pin 2 of J16. If the daughter card is to be supplied with alternate voltage
(1.8 V/2.5 V/3.3 V) then place the jumper on pin 2 and pin 3 of J16
– To supply the daughter card with 3.3 V, place the jumper on pin 1 and pin 2 of JP1
or to select 2.5 V, place the jumper on pin 3 and pin 4 of JP1, or for 1.8 V place the
jumper on pin 5 and pin 6 of JP1. Refer to table 1 for daughter card powering.
Note: At any time only one jumper should be present on JP1
●Plug in the DC power supply through the adapter (8 V - 20 V, 1 A output). As soon as
power is plugged in, the green colored LED (D8) turns on.
Note: This LED (D8) shows only whether power is connected or not. Power to the board is
selected through the power selection switch (SW5).
4.2 Address selection on the board
This evaluation board supports different temperature sensors which are present on different
daughter cards. Address lines of digital sensors are configured using the switches (SW2,
SW3, SW4) present on the motherboard.
