STM32F091RCT6TR Description
The STM32F091xB/XC microcontroller integrates a high-performance ARM Cortex - M0 32-bit RISC core that runs at up to 48 MHz, high-speed embedded memory (up to 256K bytes of flash memory and 32K bytes of SRAM), and a wide range of enhanced peripherals and IMago. The device provides standard communication interfaces (two I2C, two SPI/ and one I2S, one HDMI CEC and up to eight USART), a CAN, a 12-bit ADC, a 12-bit DAC with two channels, seven 16-bit timers, a 32-bit timer and an advanced control PWM timer. The STM32F091xB/XC microcontroller operates in the temperature range of-40 to + 85 °C and from-40 to + 105 °C with a power supply voltage of 2.0 to 3.6V. A comprehensive set of power-saving modes allows the design of low-power applications. The STM32F091xB/XC microcontroller includes seven different packaged devices with pins ranging from 48 pins to 100 pins, and core forms are available on request. Different groups of peripherals are included depending on the selected device.
