Default MCU card
Microcontrollers are supported using specialized MCU cards containing 104 pins,
which can be placed into the on-board female MCU socket. There are several
types of cards which cover multiple microcontroller families of STM32® and
different architectures. The Default MCU card that comes with the EasyMx PRO™

v7a for STM32® package is shown on Figure 4-1. It contains STM32F207VGT6
microcontroller with on-chip peripherals and is a great choice for both beginners
and professionals. After testing and building the final program, this card can also be
taken out of the board socket and used in your final device.

STM32F207VGT6 is the default chip of EasyMx PRO v7a. It has 120MHz
frequency, 1 Mbyte of Flash memory, 128K + 4K bytes of general-purpose
SRAM, integrated Ethernet controller, USB 2.0 (OTG, Host, Device), 83 General
purpose I/O pins, 12x16-bit and 2x32-bit timers, 3x12-bit A/D (24 channels),
2x12-bit D/A , 4xUSARTs, 2xUARTs, internal Real time clock (RTC), 2xI2C, 3xSPI
and 2xCAN controllers.
25MHz crystal oscillator. We carefully chose the most convenient crystal

value that provides clock frequency which can be used directly, or with the PLL
multipliers to create higher MCU clock value. MCU card also contains 32.768
kHz crystal oscillator which provides external clock for RTC module.
USB communications lines. These two jumpers, when in USB position,

connect D+ and D- lines of the on-board USB connector with PA11 and PA12
microcontroller pins. Since STM32F207VGT6 supports USB, jumpers are in
USB position.
Ethernet transceiver. Default MCU card contains single-chip Ethernet physical

ability to select specific boot space (User flash memory, system memory

pins are set to ground (0) through 100K resistors. In order to set BT0 and
PB2 pins to VCC (1), you must push SW11.1 and SW11.2 DIP switches to ON
position, Figure 4-2. The values on the BOOT pins are latched on the fourth
rising edge of system clock after a reset.
