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.
