STM32303E-EVAL evaluation board
Introduction
The STM32303E-EVAL evaluation board has been designed as a complete demonstration
and development platform for STMicroelectronic's ARM® Cortex®-M4 core-based
STM32F303VET6 microcontrollers. It features two I2Cs, three SPIs, five USARTs, one
CAN, four 12-bit ADCs, two 12-bit DACs, internal 64-KByte Data SRAM, 16-KByte Program
SRAM and 512-KByte Flash, Touch sensing, USB FS, JTAG debugging support. This
evaluation board can be used as the reference design for user application development but
it is not considered as a final application.
The full range of hardware features on the board help you to evaluate all peripherals (USB
FS, USART, Audio DAC and ADC, TFT color LCD, IrDA, LDR, MicroSD card, Motor control
connectors, Humidity Sensor, High Brightness LED, CAN, IR, EEPROM, Touch Sensing
Buttons & Temperature Sensor… etc.) and to develop your own applications. Extension
headers make it possible to easily connect a daughter board or a wrapping board for your
specific application.
An ST-LINK/V2 is integrated on the board as an embedded in-circuit debugger and
programmer for the STM32 MCU.

Overview
Delivery recommendations
Before using the board for the first time, please verify 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 from its socket by a shock.
2.
The MicroSD card which may have been ejected from the CN16 connector (right side
of the board).
3.
The dual-interface EEPROM board (ANT7-M24LR-A) which may have been unplugged
from the CN1 connector (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 the ST web site to download the relevant data
sheet and erratasheet.
Warning:
This equipment contains parts (principally an LCD), subject to
be damaged by electrostatic discharge (ESD). Before touching
the LCD or its connector (CN1 on MB895), use one of these
following ESD precautionary procedures:
Wear a ground strap. The function of such strap is to rapidly
and safely dissipate personnel static charge to the ground.
Touch the ground before all other nets or components on
board. The easiest way to proceed is to touch with a finger the

Hardware layout and configuration
The STM32303E-EVAL evaluation board has been designed around the STM32F303VET6
microcontroller (100-pin TQFP package). The hardware block diagram in Figure 2 illustrates
the connection between the STM32F303VET6 microcontroller and its peripherals (color
LCD, touch sensing buttons, USB FS connector, motor control connectors, temperature
sensor, USART, IrDA, Audio, EEPROM,RF EEPROM, MicroSD card and embedded
ST-LINK). Figure 3 helps to locate these features on the actual evaluation board.

Development and debug support
Version 2 of ST-LINK, called ST-LINK/V2, is embedded on the board. This tool allows
program loading and debugging of the STM32 on board using a JTAG or SWD interface.
The third-party debug tools are also supported by the JTAG/SWD connector, CN10, or the
ETM Trace connector, CN9.
A specific driver needs to be installed on your PC for communication with embedded STLINK/V2.The install shield called ST-LINK_V2_USBdriver.exe is available at
www.st.com/stlinkv2.
Third-party toolchains, Atollic TrueSTUDIO, KEIL® MDK-ARM, IAR® EWARM and Tasking
VX-Toolset support ST-LINK/V2 according to Table 1.

The embedded ST-LINK/V2 is connected to the PC via a standard USB cable connected to
connector CN5.The bicolor LED LD8 (COM) advises on the status of the communication as
follows:
Note:
•
Slow blinking red/off: at power on before USB init
•
Fast blinking red/off: after the first correct communication between PC and ST-Link/V2
(enumeration)
•
Red LED on: when the initialization between PC and ST-LINK/V2 has been successful
•
Green LED on: after a successful target communication initialization
•
Blinking red/green: during communication with target
•
Red on: communication finished and OK
•
Orange on: communication failure
The board can be powered via CN5 (Embedded ST/LINK/V2 USB connector) even if an
external tool is connected to CN9 (ETM Trace connector) or CN10 (External JTAG & SWD
connector).
R111 needs to be removed when using ETM 4-bit function. In this case, the key button does

Power supply
The STM32303E-EVAL evaluation board has been designed to be powered by 5 V DC
power supply and to be protected by PolyZen from wrong power plug-in event. The
evaluation board can be configured to use any of the four following sources of power supply:
•
5 V DC power adapter connected to CN14, the power jack on the board (Power supply
unit (PSU) on silkscreen of JP14). The external power supply is not provided with the
board.
•
5 V DC power with 500 mA limitation from CN5, the USB type B connector of STLINK/V2 (USB 5 V power source on silkscreen of JP14 ( STlk)).
•
5V DC power with 500mA limitation from CN12, the USB type B connector (USB 5V
power source on silkscreen of JP14 (USB)).
•
5V DC power from CN6 & CN7, the extension connectors for daughter board (daughter
board power source on silkscreen of JP14 (D5V)).
The power s4upply is configured by setting the related jumpers JP14, JP15, JP16 and JP17
as described in Table 2.

The STM32303E-EVAL evaluation board supports 2 inductor motor controls via 34-pin
connectors CN2 and CN4, which provide all required control and feedback signals to and
from the motor power-driving board.
Available signals on these connectors include emergency stop, motor speed, 3-phase motor
current, bus voltage, heatsink temperature coming from the motor driving board and 6
channels of PWM control signal going to the motor driving circuit.
Some PCB reworks are needed for motor control applications to disconnect peripherals
which share I/Os with motor control connectors and connect these I/Os to motor control
connectors.
To configure the board for motor control application, please follow the procedure below:
1.
Remove even number resistors from R1 to R58 (R2, R4, R6….R56, R58 except R12
and R22). The resistor positions on the PCB board are shown in Figure 5:

mounted by default with a 0-ohm resistor. The resistor positions on the PCB board are
shown in Figure 6:

Note:
In case of single motor applications, MC connector 2 can be considered as privileged,
because of straightforward utilization (Heatsink_Temperature of Motor control connector1
(CN2 pin 26) is not connected to an IO of STM32F303VE).
For dual motor applications:
- use MC connector 1 for motor2;
DocID026738 Rev 1

Hardware layout and configuration

- in case of 3shunt, a jumper must be placed from PD14 to PB14 across the extension
connector;
- be aware that heatsink temperature measurement must be disabled on motor2;
- be aware that MC SDK LCD UI must be disabled (conflict on SPI2 MISO).

Daughter board extension connectors (CN6 and CN7)
Two 52-pin male headers, CN6 and CN7, can be used to connect with the daughter board or
standard wrapping board to the STM32303E-EVAL evaluation board. All GPIOs are
available on them.
The space between these two connectors and the position of the power, GND and RESET
pins are defined as a standard which allows developing common daughter boards for
several evaluation boards. The standard width between CN6 pin1 and CN7 pin1 is 2700mils
(68.58 mm). This standard has been implemented on the majority of the evaluation boards.
Each pin on CN6 and CN7 can be used by a daughter board after disconnecting it from the
corresponding function block on the STM32303E-EVAL evaluation board. For more details,
see Table 26 and Table 27.

Note1:STM32F303RCT6 MCU is replaced by STM32F303RET6 so MCU pin 27(PF4 on
STM32F303RC) is replaced by GND from Rev.C1 to Rev.C2.
Note2:Text in italic placed on a wire doesn’ t correspond to net name. It just helps to identify
rapidly MCU IO related to this wire
