+	 Connectivity line devices are STM32F105xx and STM32F107xx
+	 microcontrollers.  They are intended for applications where
+	 connectivity and real-time performances are required such as
+	 industrial control, control panels for security applications, UPS or
+	 home audio.  For STM32F107xx also the Ethernet MAC is available.
