3 Introduction MMstmF0 is universal minimodule for the STMF0 microcontrollers from ST Microelectronics. This microcontroller is available in the LQFP00 case which is difficult to solder in prototype and amateur circuits due to the compactness of pins. We have undertaken an attempt at placing it on a board of xmm with a layout of leads which matches the commonly available prototype circuit boards and to EVBmmTm evaluation board. In addition, we have included Ethernet PHY 0/00Mb with RJ connector and magnetics, USB connector and socket for microsd memory card. All ports and signals of the microcontroller (except that used for Ethernet PHY) are lead out by means of two-row pin connectors with 0. (.mm) pitch. This minimodule is not only an adapter but a complete main board for STMF0 microcontroller. It needs only a connection to the supply voltage and we can start loading kbytes of Flash memory. Thanks to built-in bootloader, there is even no programmer necessary. Through integration of the peripherals with the microcontrollers on one board, the application of this module can lead to a shorter design period and facilitate the construction of systems based on ARM microcontrollers, by eliminating the need to design the printed board. The module is supplied with example software. The MMstmF0 minimodule can be also used in didactic laboratories of informatics colleges and universities, and can be also used to build circuits realizing thesis projects. Features MMstmF0 minimodule: Complete, ready to use microprocessor system Fast ARM STMF0 microcontroller with up to 90DMIPS throughput Up to kb Flash memory and up to kb RAM Onboard 0/00Mbps Ethernet PHY and RJ connector with embedded magnetics USB mini B connector microsd memory card socket JTAG/SWD for in system programming and debugging Built-in MHz system clock resonator Built-in.kHz RTC resonator Possibility to mount backup battery for RTC Onboard LED diodes for indicating Power supply, Ethernet connection status, USB status, and one user LED Module supply voltage: V x 0 terminals with 0."

8 USB interface STMF0 microcontroller have built-in USB.0 full-speed interface, which is capable of working as Host, Device or in OTG mode. Module is equipped with UBS mini B connector, power switching circuit (for Host mode) and LED diodes showing interface s power state. U (STMPSSTR) is power switch providing voltage supply to USB connector, it is controlled by MSU s PC9 pin (active low). Additionally is has short-circuit protection disconnecting power from USB connector. Fault condition is indicated by low logic level on MCU s PE pin and red LED diode USB OVC. If power switch will not be used, it can be disconnected by desoldering R and R resistors, what will make PC9 and PE pins available to other use. Thanks to D9 module can be also powered from USB connector. Presence of power supply voltage in USB connector (either from external source or from U switch) is signaled by red diode USB PWR.

11 Power supply MMstmF0 module require regulated V power supply with output current at least 00mA (when USB Hot function with capability of powering connected devices is not used) or 00mA (if this function is used). Module current draw is depended on many factors: CPU core and buses frequency, used peripherals, Ethernet controller activity, microsd activity etc. There are many possibilities to reduce power consumption thanks to microcontroller and PHY low power modes. Power supply should be connected to pins (+V) and () of J connector. Module s built in power supply is shown below: D LL U SPX90M-.

14 Programming Flash memory of STMF0 Flash memory of STMF0 microcontroller can be programmed in two ways: using JTAG/SWD interface or through bootloader. In this documentation, second method, not requiring any special programming hardware, will be described. Bootloader program is stored in internal ROM memory and allow to program Flash memory through interfaces: USB, RS and CAN. To enable bootloader, during reset BOOT0 pin (connector J, pin ) should be connected to high logic level and BOOT to low logic level (BOOT have pull-down resistor, so it can be left unconnected). Boot mode selection pins BOOT (PB) BOOT0 Boot mode X 0 Flash 0 ROM (bootloader) RAM Table MCU s boot modes. Programming through RS interface To program processor through RS, its USART port should be connected to PC using level translator, e.g. shown below: +.V RS- 9 00n 00n TX0 RX0 VCC V+ V- C+ C- C+ C n 00n PD/USART_TX PD/USART_RX MAXCSE 00n DB9F Figure RS level translator. Pins RS of USART (PA0) and CAN (PB) should be connected to steady logic state, USB interface should be not connected.
