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.

For information on programming, erasing and protection of the internal Flash memory

please refer to the STM32F10xxx Flash programming manual.

The reference and Flash programming manuals are both available from the

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 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 I2Cs, 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 three

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.

These features make the STM32F105xx and STM32F107xx connectivity line

microcontroller family suitable for a wide range of applications such as motor drives and

application control, medical and handheld equipment, industrial applications, PLCs,

inverters, printers, and scanners, alarm systems, video intercom, HVAC and home audio

equipment.
