2 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 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 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.
