Hardware and layout

The STM32F0DISCOVERY is designed around the STM32F051R8T6 microcontroller in a 64-pin LQFP package. Figure 2 illustrates the connections between the STM32F051R8T6 and its peripherals (STLINK/ V2, push button, LEDs and connectors). Figure 3 and Figure 4 help you to locate these features on the STM32F0DISCOVERY.

STM32F051R8T6 microcontroller
This 32-bit low- and medium-density advanced ARM™ MCU with a high-performance ARM Cortex™-M0 32-bit RISC core has 64 Kbytes Flash, 8 Kbytes RAM, RTC, timers, ADC, DAC, comparators and communication interfaces.

The STM32 F0 delivers 32-bit performance and STM32 DNA essentials into applications typically addressed by 8- or 16-bit microcontrollers. It benefits from the combination of realtime performance, low-power operation, advanced architecture and peripherals associated to the STM32 ecosystem, which has made the STM32 a reference in the market.

Embedded ST-LINK/V2
The ST-LINK/V2 programming and debugging tool is integrated on the STM32F0DISCOVERY. The embedded ST-LINK/V2 can be used in 2 different ways according to the jumper states (see Table 3):

• Program/debug the MCU on board,
• Program/debug an MCU in an external application board using a cable connected to SWD connector CN3.

The embedded ST-LINK/V2 supports only SWD for STM32 devices. For information about debugging and programming features refer to user manual UM1075 (ST-LINK/V2 in-circuit debugger/programmer for STM8 and STM32) which describes in detail all the ST-LINK/V2 features.
Table 3. Jumper states

Jumper state	Description
Both CN2 jumpers ON	ST-LINK/V2 functions enabled for on board programming (default)
Both CN2 jumpers OFF	ST-LINK/V2 functions enabled for application through external CN3 connector (SWD supported)

1. Using ST-LINK/V2 to program/debug the STM32 F0 on board
   To program the STM32 F0 on board, simply plug in the two jumpers on CN2, as shown in Figure 8 in red, but do not use the CN3 connector as that could disturb communication with the STM32F051R8T6 of the STM32F0DISCOVERY.
2. Using ST-LINK/V2 to program/debug an external STM32 application
   It is very easy to use the ST-LINK/V2 to program the STM32 on an external application. Simply remove the 2 jumpers from CN2 as shown in Figure 9, and connect your application to the CN3 debug connector according to Table 4.
   Note: SB19 and SB22 must be OFF if you use CN3 pin 5 in your external application.
   Table 4. Debug connector CN3 (SWD

   Pin	CN3	Designation
   1	VDD_TARGET	VDD from application
   2	SWCLK	SWD clock
   3	GND	Ground
   4	SWDIO	SWD data input/output
   5	NRST	RESET of target MCU
   6	SWO	Reserved

   

Power supply and power selection
The power supply is provided either by the host PC through the USB cable, or by an external 5V power supply.
The D1 and D2 diodes protect the 5V and 3V pins from external power supplies:

• 5V and 3V can be used as output power supplies when another application board is connected to pins P1 and P2. In this case, the 5V and 3V pins deliver a 5V or 3V power supply and power consumption must be lower than 100 mA.
• 5V can also be used as input power supplies e.g. when the USB connector is not connected to the PC.

In this case, the STM32F0DISCOVERY board must be powered by a power supply unit or by auxiliary equipment complying with standard EN-60950-1: 2006+A11/2009, and must be Safety Extra Low Voltage (SELV) with limited power capability.

LEDs

• LD1 PWR: Red LED indicates that the board is powered.
• LD2 COM: Tricolor LED (COM) advises on the communication status as follows:
  • Slow blinking Red LED/Off: At power on before USB initialization
  • Fast blinking Red LED/Off: After the first correct communication between PC and STLINK/V2 (enumeration)
  • Red LED On: When initialization between PC and ST-LINK/V2 is successfully finished
  • Green LED On: After successful target communication initialization
  • Blinking Red/Green LED: During communication with target
  • Red LED On: Communication finished and OK
  • Orange LED On: Communication failure
• User LD3: Green user LED connected to the I/O PC9 of the STM32F051R8T6.
• User LD4: Blue user LED connected to the I/O PC8 of the STM32F051R8T6.

Push buttons

• B1 USER: User push button connected to the I/O PA0 of the STM32F051R8T6.
• B2 RESET: Push button used to RESET the STM32F051R8T6.

JP2 (Idd)
Jumper JP2, labeled Idd, allows the consumption of STM32F051R8T6 to be measured by removing the jumper and connecting an ammeter.

• Jumper on: STM32F051R8T6 is powered (default).
• Jumper off: an ammeter must be connected to measure the STM32F051R8T6 current, (if there is no ammeter, the STM32F051R8T6 is not powered).

OSC clock

1. OSC clock supply
   PF0 and PF1 can be used as GPIO or as HSE oscillator. By default these I/Os are configured as GPIO, so SB16 and SB17 are closed, SB18 is open and R22, R23, C13 and C14 are not populated. An external HSE clock can be provided to the MCU in three ways:
   • MCO from ST-LINK. From MCO of the STM32F103. This frequency cannot be changed, it is fixed at 8 MHz and connected to PF0-OSC_IN of the STM32F051R8T6. Configuration needed:
     • SB16, SB18 CLOSED
     • R22, R23 removed
     • SB17 OPEN
   • Oscillator onboard. From X2 crystal (not provided). For typical frequencies and its capacitors and resistors, please refer to the STM32F051R8T6 Datasheet. Configuration needed:
     • SB16, SB17 SB18 OPEN
     • R22, R23, C13, C14 soldered
   • Oscillator from external PF0. From external oscillator through pin 7 of the P1 connector. Configuration needed:
     • SB16, SB17 CLOSED
     • SB18 OPEN
     • R22 and R23 removed
2. OSC 32 KHz clock supply
   PC14 and PC15 can be used as GPIO or as LSE oscillator. By default these I/Os are configured as GPIO, so SB20 & SB21 are closed and X3, R24, R25 are not populated. An external LSE clock can be provided to the MCU in two ways:
   • Oscillator onboard. From X3 crystal (not provided). Configuration needed:
     • SB20, SB21 OPEN
     • C15, C16, R24 and R25 soldered.
   • Oscillator from external PC14. From external oscillator trough the pin 5 of P1 connector. Configuration needed:
     • SB20, SB21 CLOSED
     • R24 and R25 removed

Connecting modules on the prototyping board

This section gives some examples of how to connect ready-to-use modules available from different manufacturers to the STM32F0DISCOVERY kit via the prototyping board included in the kit.
Software examples, based on the connections described below, are available at www.st.com/stm32f0discovery.

Mikroelektronica accessory boards
Mikroelektronika, http://www.mikroe.com, has specified two standard connectors for their accessory boards, named mikroBUS™ (http://www.mikroe.com/mikrobus_specs.pdf) and IDC10.
MikroBUS™ is a 16-pin connector to connect accessory boards very quickly and easily to a microcontroller board through SPI, USART or I2C communications, along with additional pins such as Analog Input, PWM and Interrupt. The set of mikroElektronika boards compatible with mikroBUS™ is called “Click boards”. IDC10 is a 10-pin connector to connect the general purpose I/O of an MCU to other accessory boards.
The tables below are one solution for connecting mikroBUS™ and IDC boards to the STM32F0DISCOVERY; this solution used in the different examples is available at www.st.com/stm32f0discovery.

Note: For an up-to-date list, visit http://www.st.com/internet/evalboard/subclass/1116.jsp. The DIL24 boards are described as “adapter boards” in the field “General Description”.

Arduino shield boards
Arduino™ is an open-source electronics prototyping platform based on flexible, easy-to-use hardware and software. See http://www.arduino.cc for more information. Arduino accessory boards are called “Shields” and can be easily connected to the STM32F0 Discovery according to the following table.
