STM32F091CBT6 Datasheet PDF - ST Microelectronics

The STM32F091CBT6 is an entry level STM32 F0 series 32-bit Microcontroller incorporates the high-performance ARM Cortex-M0 RISC core operating at a 48MHz frequency, high speed embedded memories (Flash memory up to 128kB and SRAM up to 32KB) and an extensive range of enhanced peripherals and I/Os. This device offer standard communication interfaces (two I²Cs, two SPIs, two I²Ss, one HDMI CEC and six USARTs), one CAN, one 12-bit ADC, one 12-bit DAC with two channels, seven 16-bit timers, one 32-bit timer and an advanced control PWM timer.
