ST STM32F091RCH6TR High-Performance Mainstream Arm Cortex-M0 Access line 32-Bit Microcontrollers MCU

Product Description Of STM32F091RCH6TR
STM32F091RCH6TR microcontrollers incorporate the high-performance ARM®Cortex®-M0 32-bit RISC core operating at up to 48 MHz frequency, high-speed embedded memories (up to 256 Kbytes of Flash memory and 32 Kbytes of SRAM), and an extensive range of enhanced peripherals and I/Os. The device offers standard communication interfaces (two I2Cs, two SPIs/one I2S, one HDMI CEC and up to eight 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.

STM32F091RCH6TR microcontrollers operate in the -40 to +85 °C and -40 to +105 °C temperature ranges, from a 2.0 to 3.6 V power supply. A comprehensive set of power-saving modes allows the design of low-power applications.
