Product Summary

The STM32F105R8T6 is a connectivity line incorporates the highperformance ARM CortexTM-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. The STM32F105R8T6 offers 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 STM32F105R8T6 only. The The STM32F105R8T6 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.
