Evaluation board with STM32F091VC MCU
Introduction
The STM32091C-EVAL evaluation board is designed as a complete demonstration and
®
®
development platform for STMicroelectronics ARM
Cortex
-M0 core-based
2
STM32F091VCT6 microcontroller, with two I
Cs, two SPIs, eight USARTs, one CAN, 12-bit
ADC, 12-bit DAC, two GP comparators, internal SRAM and 256-Kbyte Flash
memory,
Touch sensing, CEC and SWD debugging support.
The full range of hardware features on the board helps the user to evaluate all the
peripherals (8x USARTs, RS-232, RS-485, Audio DAC, microphone ADC, Touch sensing
buttons, TFT LCD, CAN, IrDA, IR LED, IR receiver, LDR, microSD card, CEC on two HDMI
connectors, smartcard slot, RF-EEPROM and temperature sensor) and to develop
applications. Extension headers make it possible to easily connect a daughterboard or
wrapping board for a specific application. An ST-LINK/V2-1 is integrated on the board as an
embedded in-circuit debugger and programmer for the STM32.

ST-LINK/V2-1 (either available from Microsoft website or included in the USB driver for ST-LINK/V2 for XP). In case the STM32091C-EVAL evaluation board is connected to the PC before the driver is installed, some STM32091C-EVAL interfaces may be declared as “Unknown” in the PC device manager. -
Page 12: St-Link/V2-1 Firmware Upgrade
PC only provides 100 mA to the board at that time. During the USB enumeration, the STM32091C-EVAL board asks for the 300 mA power to the host PC. If the host is able to provide the required power, the enumeration finishes by a “SetConfiguration” command and then, the power transistor U23 (ST890) is switched ON, the red LED LD5 is turned ON, thus STM32091C-EVAL board can consume maximum 300 mA current, but not more. -
Page 13: Figure 6. Structure Of The Power Source
UM1817 Hardware layout and configuration If this order is not respected, the board may be powered by VBUS first then E5V or D5V, and the following risks may be encountered: If more than 300 mA current is needed by the board, the PC may be damaged or current can be limited by PC. -

Description JP15 is used to select one of the three possible power supply resources. For power supply jack (CN16) to the STM32091C-EVAL only, JP15 is set as shown to the right: For power supply from the daughterboard connectors (CN7) to STM32091C-... -

LD8 is lit when VDD < 2V and in this case STM32 is not functional. LD9 is lit when VDDA < 2.4 V and in this case analogue parts in STM32F091VCT6 are not functional. The LED LD5 is lit when the STM32091C-EVAL evaluation board is powered by the 5 V correctly. -

The signal Bootloader_RESET (shared with CTS signal) and the Bootloader_BOOT0 (shared with DSR signal) are added on the RS-232 connector CN9 for ISP support. -
Page 19: Touch Sensing Buttons
Default Setting: Not fitted Touch sensing buttons Two touch sensing buttons are supported on the STM32091C-EVAL evaluation board and they are connected to three capacitive sensing channels (PD[12:14]) in group8 with active shield being connected to two capacitive sensing channels (PB11 and PB12) in group6 (see Table 12). -
Page 20: Microsd Card
R37 must be removed to avoid disturbance due to the capacitor. Note: Touch sensing buttons are fully functional only when the STM32091C-EVAL board is powered on in power mode 1 (both VDD and VDDA are connected to fixed 3.3 V). It is potentially necessary to adjust the capacitor value of C8 and the firmware to adapt them to the voltage range from 1.65 V to 3.6 V of VDD on power-mode 2 and 3. -
Page 21: Ldr (Light Dependent Resistor)
The VDDA is divided by resistor bridge of LDR VT9ON1 and 8.2K resistor and connected to PA1 (COM1_IN+/ADC IN1) as shown below in Figure 7 on the STM32091C-EVAL evaluation board. Figure 7. GP comparator 1 It is possible to compare LDR output with 1/4 band gap, 1/2 band gap, 3/4 band gap, band gap and DAC1 OUT and to connect LDR output to ADC IN1 for AD conversion. -
