Technical Datasheet

The STM32F105RBT6 connectivity line family incorporates the highperformance ARM® Cortex®-M3 32-bit RISC core operating at a 72 MHz frequency, highspeed 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 STM32F105RBT6  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 STM32F105RBT6  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.
