Evaluation board for STM32 F0 series with STM32F072VB MCU
IntroductionThe STM32072B-EVAL evaluation board is designed as complete demonstration and development platform for STMicroelectronics ARM cortex-M0 core-based STM32F072VBT6 microcontroller with two I2C, two SPI, four USART, one CAN, 12bit ADC, 12bit DAC, two GP comparators, internal 16KB SRAM and 128KB Flash, USB FS, Touch sensing, CEC, SWD debugging support.
The full range of hardware features on the board is designed for the evaluation of all the peripherals (for example the motor control connector, USB full-speed, RS232, RS485, Audio DAC, microphone ADC, Touch sensing buttons, TFT LCD, CAN, IrDA, IR LED, IR receiver, LDR, MicroSD card, CEC on two HDMI connectors, Smart card slot, RF E2PROM and the temperature sensor) and for the development of user-specific applications. Extension headers are used to easily connect a daughter board or wrapping board for the user-specific applications.
The ST-LINK/V2 is integrated on the board as embedded in-circuit debugger and programmer for the STM32 MCU.

1.4 Delivery recommendationsBefore using the board for the first time, please verify that nothing was damaged during shipment and that no components are unplugged or lost.
When extracting the board from its plastic container, please check that no component remains in the bag.
The main components to verify are the following:
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 CN9 connector (right side of the board).
3. The dual-interface EEPROM board (ANT7-M24LR-A) which may have been unplugged from the CN2 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 company web site to download the relevant data sheet and errata sheet.

2.1 Development and debug supportThe version 2 of the ST-LINK called ST-LINK/V2 is embedded on the board. This tool is used for program loading and debugging of the STM32F072VBT6 on board using the SWD interface. The third-party debug tools are also supported by SWD with connectors CN11 and CN12.
A specific driver needs to be installed on your PC for the communication with the embedded ST-LINK/V2.The install shield called ST-LINK_V2_USBdriver.exe is available on the company website. To download and install this driver, please refer to the software and development tools page for STM32F0 family available on www.st.com.
The third-party tool chains, Atollic TrueSTUDIO, KEIL ARM-MDK, IAR EWARM and the 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 CN13.The bicolor LED LD9 (COM) indicates the status of the communication as follows:
• Slow blinking Red/Off: at power on before USB init
• Fast blinking Red/Off: after the first correct communication between the PC and ST-LINK/V2 (enumeration)
• Red Led On: when initialization between PC and ST-LINK/V2 is successfully complete
• Green Led On: after successful target communication initialization
• Blinking Red/Green: during communication with target
• Red On: communication finished and OK
• Orange On: communication failure
Note: It is possible to power the board via CN13 (embedded ST/LINK/V2 USB connector) even if an external tool is connected to CN11 (high-density SWD connector) or CN12 (SWD connector).

2.2 Power supplyThe STM32072B-EVAL evaluation board is power supplied by 5V DC supply and protected by PolyZen in case of wrong power plug-in event. It is possible to configure the evaluation board to use any of the four following sources for the power supply:
• 5V DC power adapter connected to CN17, the Power Jack on the board (Power Supply Unit (PSU) on silk screen of JP19). The external power supply is not provided with the board.
• 5V DC power with 500 mA limitation from CN13, the USB type B connector of ST-LINK/V2 (USB 5 V power source (STlk) on silk screen of JP19).
• 5V DC power with 500 mA limitation from CN4, the USB type B connector (USB 5 V power source (U5V) on silk screen of JP19).
• 5V DC power from CN8, the extension connector for daughter board (daughter board power source (D5V) on silk screen of JP19).
The power source is selected by setting the related jumpers JP19, JP11 and JP14 as described in Table 2.

Note: VDD_MCU Idd measurement can be done by the current Ammeter which is mounted on JP12 when it is open. VDDIO2 Idd measurement can be done by the current Ammeter which is mounted on JP16 when it is open.
JP9 must be open (to disconnect VDDA from all analog power VDD_ANA which is connected to analog circuits on the board) for MCU Idd measurement.
LD5 is lit when VDD<2V and in this case MCU is not functional. LD6 is lit when VDDA<2.4V and in this case analogue parts in STM32F072VBT6 are not functional.
The LED LD7 is lit when the STM32072B-EVAL evaluation board is powered by the 5V.
Table 4 shows the low-voltage limitations that might apply depending on the characteristics of some peripheral components. The components may work incorrectly when the power level is lower than the limitation.
Caution: JP12 and JP16 must not be opened; otherwise STM32F072VBT6 will be damaged due to the lack of power supply on its power pins.
Caution: There is a risk of explosion if the battery is replaced with the wrong type of battery. Dispose of used batteries according to the instructions.

Note: the touch sensing buttons are fully functional only when STM32072B-EVAL is powered in power mode 1 (both VDD & VDDA is connected to fixed 3.3 V). It is potentially necessary to adjust the capacitor value of C28 and the firmware to adapt them to the voltage range from 1.65 V to 3.6 V of VDD in power modes 2 and 3.
2.9 MicroSD cardThe 2 GB (or more) MicroSD card is available on the board. It is connected to SPI1 port (shared with color LCD) of STM32F072VBT6. The MicroSD card detection is managed by the standard IO port PB15 and it should be set with internal pull-up.
2.10 Analog inputThe two-pin header CN18 and the 10K ohm potentiometer RV3 are connected to PC0 of STM32F072VBT6 as analog input. A low pass filter can be implemented by replacing R206 and C113 with the right values of resistor and capacitor as requested by end user application.
2.11 LDR (Light Dependent Resistor)The VDDA is divided by the resistor bridge of LDR VT9ON1 and 8.2K resistor, and connected to PA1 (COM1_IN+/ADC IN1) as shown below on the STM32072B-EVAL evaluation board.

The I2C address of the temperature sensor is 0b100100x, where x can be 0 or 1 depending on the setting of SB6.
Note: the temperature result measured from STLM75M2F can be a little higher than the ambient temperature due to the power dissipation of the components on the board.
2.13 USBSTM32072B-EVAL evaluation board supports USB2.0 compliant full speed communication via a USB type B connector (CN4). The evaluation board can be powered by this USB connection at 5 V DC with 500 mA current limitation.

3.6 Daughter board extension connector CN7 and CN8Two 52-pin male headers CN7 and CN8 can be used to connect with the daughter board or with the standard wrapping board to STM32072B-EVAL evaluation board. All GPI/Os are available on the connector. The space between these two connectors and position of power, GND and RESET pin are defined as a standard, allowing the development of common daughter boards for several evaluation boards. The standard width between CN7 pin1 and CN8 pin1 is 2700mils (68.58mm). The standard was implemented on the majority of evaluation boards.
