STM32F091VCT7 Description
The STM32F091xB/xC microcontrollers incorporate the high-performanceARM? Cortex?-M0 32-bit RISC core operating at up to 48 MHz frequency, high-speedembedded memories (up to 256 Kbytes of Flash memory and 32 Kbytes of SRAM), and anextensive range of enhanced peripherals and I/Os. The device offers standardcommunication interfaces (two I2Cs, two SPIs/one I2S, one HDMI CEC and up to eightUSARTs), one CAN, one 12-bit ADC, one 12-bit DAC with two channels, seven 16-bittimers, one 32-bit timer and an advanced-control PWM timer.
