STM32F091CCT6TR

STM32F091CCT6TR                           Description

The STM32F091xB/xC 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.

The STM32F091xB/xC 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. The STM32F091xB/xC microcontrollers include devices in seven different packages ranging from 48 pins to 100 pins with a die form also available upon request. Depending on the device chosen, different sets of peripherals are included.
