The STM32F091CCU6TR with ARM Microcontrollers - MCU Mainstream Arm Cortex-M0 Access line MCU is a powerful system-on-a-chip (SoC) from STMicroelectronics. This device combines a 32-bit Cortex-M0+ CPU with 256KB of Flash memory, CAN and C interfaces, and an extensive set of peripherals. The CPU runs up to 48MHz and is perfect for simple, low-power applications. The integrated CAN interface makes it possible to connect the SoC to CAN bus networks, while the integrated C interface allows for easy connection to various sensor and other devices. The included peripherals allow for a range of digital and analog I/O, plus CAN, serial interfaces, and a low power real-time clock. With the on-chip analog comparators, analog-to-digital converters, timers, and more, the device is ideal for applications requiring simple control and sensor monitoring.
