STM32373C-EVAL evaluation board
Introduction
The STM32373C-EVAL evaluation board is designed as a complete demonstration and
development platform for STMicroelectronics’ ARM cortex-M4 core-based
STM32F373VCT6 microcontroller. It features two I2Cs, three SPIs, three USARTs, one
CAN, one CEC controller, one 12-bit ADC, three 16-bit sigma delta ADCs, three 12-bit
DACs, internal 32-KByte SRAM and 256-KByte Flash, touch sensing, USB FS, and JTAG
debugging support. This evaluation board can be used as a reference design for user
application development but it is not considered as the final application.
The full range of hardware features on the board can help the user evaluate all peripherals
(USB FS, USART, audio DAC, microphone ADC, color LCD, IrDA, LDR (light-dependent
resistor), MicroSD card, HDMI CEC, ECG (electrocardiogram), pressure sensor, CAN, IR
(infrared) transmitter and receiver, EEPROM, touch slider, temperature sensor, etc.) and
develop their own applications. Extension headers make it possible to easily connect a
daughterboard or wrapping board for a specific application.
An ST-LINK/V2 is integrated on the board as an embedded in-circuit debugger and
programmer for the STM32 MCU.

Note:
The touch slider is only fully functional when the STM32373C-EVAL is powered on Power
mode 1 (both VDD and VDDA are connected to a fixed 3.3 V power supply). When the
STM32373C-EVAL is powered on Power mode 2, it may be necessary to adjust the
capacitor value of C123 and the firmware so they are adapted to a voltage range of 2.0 V to
3.6 V of VDD. The touch slider is not functional when the STM32373C-EVAL is powered on
Power mode 3 because some IOs are also powered by the VDDA domain.

Electrocardiogram demonstration
The electrocardiogram (ECG) demonstration is implemented on the STM32373C-EVAL
evaluation board. There are two ECG electrodes, TS1 and TS2, on the board for fingers
from the right and left hands of the human body. The first stage of the ECG amplifier circuit
is an instrument amplifier INA333 (U2). The gain is set to 5. The gain of the second amplifier
stage (U3A) is set to 10 or 40. The total gain of the circuit outside the microcontroller is set
to 50 or 200. The output of the amplifier is connected to the sigma delta ADC in the
STM32F373VCT6 through PE12.
Jumper JP1 can change the second stage amplifier gain (see Table 15).
Table 15.
Jumpers of the ECG amplifier
Jumper
JP1
Description
When JP1 is closed, the second amplifier gain is changed from 10 to 40.
Default setting: fitted.
A low-pass filter is available on the evaluation board but, by default, it is not used. This filter
is made of a second order Sallen-Key Low-pass Filter (U3C) having unitary gain and 9 Hz
cut-off frequency. It can be used in noisy environments to improve 50 Hz or 60 Hz noise
rejection.
This filter is enabled by removing R14 and soldering 0 Ω on the R183 footprint.
Caution is needed for ECG detection and heartbeat measurement. The recommendations
are:
22/66
1.
Humid air and fingers
2.
Large area in contact with the electrodes
3.
Relaxed body with no movement
4.
Digital (and or) analog filtering to improve 50 Hz or 60 Hz noise rejection
5.
Third electrode usage connected to GND
6.
Evaluation board preferably powered by USB
7.
Body must be electrically isolated from earth

Hardware layout and configuration
PT100 temperature sensor
There is a current source circuit on the STM32373C-EVAL evaluation board to provide a
fixed 1 mA current (when VDD = 3.3 V) to the platinum probe PT100 (R30). The R30 voltage
level is directly applied to the sigma delta ADC of the STM32F373VCT6, through PE7, to
measure the temperature value on PT100.
For temperatures lower than 100 °C, the resistor value is given by Equation 1.
Equation 1
R PT100 = 100 + 0.385 × T
T is the temperature in degrees Celsius.
The principle of the PT100 temperature sensor measurement is given in Figure 4.

The operational amplifier, A1, and the resistors R1 to R5 form a differential amplifier with a
differential gain (GA1).
Due to the resistor values chosen, GA1 is equal to 1. This is known because the resistor
bridge, R1 and R2, connected to VDD is equivalent to the VDD/2 generator where R1/2 = R
internal resistor.
The voltage on Rref is given in Equation 2 to Equation 5.

Hardware layout and configuration
UM1564
Equation 2
V OUTA1 = V REF + V OUTA2 (since G A1 = 1 )
Equation 3
V OUTA2 = V PT100
Equation 4
V REF = V OUTA1 – V PT100
Equation 5
V Rref = V ref = VDD ⁄ 2
The voltage on the ADC input is given in Equation 6.
Equation 6
V ADC = V PT100 = V Rref × R PT100 ⁄ R ref = R PT100 × VDD ⁄ ( 2 × R ref )
The measured PT100 value given by the ADC is shown in Equation 7.
Equation 7
R PT100 = [ V ref_ADC × N ⁄ ( 2
16
– 1 ) ] × 2 × R ref ⁄ ( VDD )
Where:
●
N is the value returned by the ADC corresponding to the voltage measured.
●
Vref_ADC is the ADC reference voltage (SD_VREF+ in Figure 26).
If Vref_ADC = VDD, the RPT100 value becomes as shown in Equation 8.
Equation 8
R PT100 = [ N ⁄ ( 2
16
– 1 ) ] × 2 × R ref
Conclusion
When the JP17 jumper is closed and the external reference voltage selected (Vref_ADC)
equals VDD, the temperature measurement becomes VDD independent.
Table 16 shows the voltage range corresponding to different temperatures for the ADC IN of
the STM32F373VCT6 where gain = 16.

Pressure sensor
An absolute pressure sensor with 1000 HP, full scale MPX2102, and an analog front end is
implemented on the STM32373C-EVAL board. The output differential pair is connected to
the sigma delta ADC in the STM32F373VCT6 via PE8 (P) and PE9 (N).
The principle of the pressure measurement is given in Figure 5.

The differential voltage, at output, of the amplifier is given in Equation 9.
Equation 9
V OUT+ – V OUT- = ( V IN+ – V IN- ) × ( G + R2 ⁄ R3 ) – VDD × R2 ⁄ R3
where:
26/66
●
G represents the operational amplifier differential gain when R3 is infinite.
●
G = 2 * R2/R1 + 1
Doc ID 023566 Rev 1
UM1564
Hardware layout and configuration
The operational amplifier differential input voltage provided by the pressure sensor is given
in Equation 10.
Equation 10
V IN+ – V IN- = P m × K × VDD
Where:
●
Pm = the pressure measured
●
K = sensitivity of the sensor (40 mV for VDD = 10 V and 1000 HPa)
The ADC output is related to the differential voltage by Equation 11.
Equation 11
V ADC = V ref_ADC × N ⁄ ( 2
16
– 1 ) = [ P m × K × VDD × ( G + R2 ⁄ R3 ) – VDD × R2 ⁄ R3 ] × G ADC
where:
●
N is the value returned by the ADC corresponding to the pressure measured
●
Vref_ADC is the ADC reference voltage (SD_VREF+ in Figure 26)
●
GADC is the ADC digital gain
So, if Vref_ADC = VDD Equation 11 becomes Equation 12.
Equation 12
N ⁄ (2
16
– 1 ) = [ P m × K × ( G + R2 ⁄ R3 ) – R2 ⁄ R3 ] × G ADC
Conclusion
Note:
1.
When the ADC external reference voltage is selected and JP17 jumper is closed,
Vref_ADC = VDD so the pressure measurement becomes VDD independent.
2.
The R2/R3 term in Equation 11 and Equation 12 allows the offset voltage
corresponding to atmospheric pressure to be partially reduced. Consequently, the
digital gain can be increased to improve sensitivity.
VTEMP may be used to compensate the temperature sensor drift by measuring the sensor
current change with temperature.

Daughterboard extension connectors CN13 and CN14
Two 50-pins male header connectors CN13 and CN14 can be used to connect with
daughterboard or standard wrapping board to STM32373C-EVAL evaluation board. All
GPI/Os are available on them. The space between these two connectors and position of
power, GND and RESET pins are defined as a standard which allows to develop common
daughterboards for several evaluations boards.
The standard width between CN13 pin1 and CN14 pin1 is 2700 mils (68.58 mm). The
standard was implemented on the majority of evaluation boards. Each pin on CN13 and
CN14 can be used by a daughterboard after disconnecting it from the corresponding
