Introduction
This datasheet provides the description of the STM32F105xx and STM32F107xx
connectivity line microcontrollers. For more details on the whole STMicroelectronics
STM32F10xxx family, please refer to
Section 2.2: Full compatibility throughout the family.
The STM32F105xx and STM32F107xx datasheet should be read in conjunction with the
STM32F10xxx reference manual.

Description
The STM32F105xx and STM32F107xx connectivity line family incorporates the high-
performance ARM
®
Cortex™-M3 32-bit RISC core operating at a 72 MHz frequency, high-
speed embedded memories (Flash memory up to 256 Kbytes and SRAM up to 64 Kbytes),
and an extensive range of enhanced I/Os and peripherals connected to two APB buses. All
devices offer two 12-bit ADCs, four general-purpose 16-bit timers plus a PWM timer, as well
as standard and advanced communication interfaces: up to two I
2
Cs, three SPIs, two I2Ss,
five USARTs, an USB OTG FS and two CANs. Ethernet is available on the STM32F107xx
only.
The STM32F105xx and STM32F107xx connectivity line family operates in the –40 to
+105 °C temperature range, from a 2.0 to 3.6 V power supply. A comprehensive set of
power-saving mode allows the design of low-power applications.
The STM32F105xx and STM32F107xx connectivity line family offers devices in two different
package types: from 64 pins to 100 pins. Depending on the device chosen, different sets of
peripherals are included, the description below gives an overview of the complete range of
peripherals proposed in this family.
