STEVAL-PCC012V1 STM32F107xx connectivity gateway,
demonstration board
1 Introduction
This user manual describes the implementation of the STEVAL-PCC012V1 demonstration
board. The STEVAL-PCC012V1 demonstration board is equipped with an Ethernet
interface, four digital/analog extension connectors (I2C, SPI, etc.), two footprint positions for
two different Wi-Fi modules, an OFDM PRIME power line networking extension connector
and a microSD™ Card socket with SPI interface. It also features a 5-way general purpose
joystick, four general purpose LEDs and two LEDs dedicated to user interface.
The demonstration board also includes digital/analog input/output connectors pinout
compatible with existing demonstration boards from STMicroelectronics™:
●STEVAL-CCA021V1 - audio demonstration board (stereo DAC, Class-D amplifier)
●STEVAL-MKI0xxV1 - MEMS demonstration boards (gyroscope, accelerometer) that
are compatible with 24 DIL socket
●EVALST7590-1 - ST7590 “PRIME” board - narrow-band OFDM power line networking
PRIME compliant system-on-chip.
The demonstration board can be supplied from a standard DC power supply (7 - 35 V DC)
or directly using a 24 V DC industrial mains supply.

Configuration UM0896
10/43 Doc ID 17009 Rev 1
5 Configuration
5.1 Ethernet
An Ethernet PHY U5 is available on the board. It is connected through the media
independent interfaces (MII, and reduced MII, RMII) to the Ethernet MACs of the STM32™
microcontroller.
If the Ethernet PHY is used, the crystal resonator X2 must be chosen as STM32 clock
source.
The clock source for the PHY is the clock output MCO signal of the STM32 microcontroller.
To operate in MII mode, the MCO signal must be configured to output 25 MHz, for RMII,
50 MHz.
By default the MII address of the Ethernet PHY is 0x01 and the initial configuration of the
Ethernet PHY is selected as shown in Table 2.
There are two LEDs embedded in RJ45 connector (CN5) which are used to indicate the
status of the line:
●The green LED in the connector is switched on continuously when the Ethernet link is
established with the counterpart.
●The yellow LED in the connector blinks when a transmission or a reception is ongoing.
The “Serial Management Interface” (SMI) is part of the MII interface and is used to transfer
management information between MAC and PHY (access of the PHY registers).
The PHY can communicate with the STM32 microcontroller over MII or RMII. SB1, SB2 and
SB3 must be configured according to the mode chosen. MII is chosen as a default option.
