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.

2.1 Development and debug support

Version 2 of the ST-LINK (ST-LINK/V2) is embedded on the board. This tool allows onboard
program loading and debugging of the STM32F373VCT6 using the JTAG or SWD interface.
Third-party debug tools are also supported using the JTAG/SWD connector (CN17) or the
ETM trace connector (CN15).

A specific driver needs to be installed on your PC for communication with the embedded
ST-LINK/V2. The install shield, called ST-LINK_V2_USBdriver.exe, is available from the ST
website. To download and install this driver, please refer to the software and development
tools page of the STM32F family on www.st.com.

Third-party toolchains, Atollic TrueSTUDIO, KEIL ARM-MDK, IAR EWARM, and Tasking
VX-Toolset support ST-LINK/V2 according to Ta bl e 2 .

STM32373C-EVAL evaluation board supports USB2.0 compliant, full-speed communication
via a USB type B connector (CN16). The evaluation board can be powered by this USB
connection at 5 V DC with 500 mA current limitation.

USB disconnection simulation can be implemented by controlling an external 1.5 KΩ pull-up
resistor on the USB+ line. The pull-up function can be enabled by PC5.

The USB operates correctly when VDD > 3 V.

2.9 RS-232 and IrDA

RS-232 (with hardware flow control clear to send (CTS) and request to send (RTS)) and
IrDA communication are supported by:

● D-type 9-pin RS-232 connector (CN12)

● IrDA transceiver (U12)

They are connected to USART2 of the STM32F373VCT6 on the STM32373C-EVAL

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.

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 Tabl e 15).

Table 15. Jumpers of the ECG amplifier

Jumper Description

JP1

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:

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

2.18 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

T is the temperature in degrees Celsius.

The principle of the PT100 temperature sensor measurement is given in Figure 4.

differential gain (G

Due to the resistor values chosen, G

2.19 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 operational amplifier differential input voltage provided by the pressure sensor is given

Conclusion

1. When the ADC external reference voltage is selected and JP17 jumper is closed,

V

= 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.
