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.

1.3 Order code
To order the STM32F373VCT6 evaluation board, use the order code STM32373C-EVAL.
1.4 Delivery recommendations
Some verification of the board is needed before using it for the first time to make sure that
nothing was damaged during shipment and that no components are unplugged or lost.
When the board is extracted from its plastic bag, please check that no component remains
in the bag.
The main components to verify are:
1. The 8-MHz crystal (X2) which may have been removed by a shock from its socket.
2. The MicroSD card which may have been ejected from the connector CN7 (right side of
the board).
3. The dual-interface EEPROM board (ANT7-M24LR-A) which may have been unplugged
from the connector CN3 (top left corner of the board).
For all information concerning the version of the MCU used on the board, its specification
and possible related limitations, please visit www.st.com to download the relevant data
sheet and erratasheet.
Caution: There is an explosion risk if the battery is replaced by an incorrect one. Make sure to
dispose of used batteries according to the instructions.

2 Hardware layout and configuration
The STM32373C-EVAL evaluation board is designed around the STM32F373VCT6 (100-
pin LQFP package). The hardware block diagram, Figure 2, illustrates the connection
between the STM32F373VCT6 and the peripherals (color LCD, touch slider, USB FS
connector, temperature sensor, USART, IrDA, audio, EEPROM, RF EEPROM, MicroSD
card, and embedded ST-LINK). Figure 3 illustrates how to locate these features on the
actual evaluation board. Features described in Section 2.1 to Section 2.24 below are shown
in Figure 3.
