The 48 MHz clock on the Cortex-M0 core is the processing ceiling for this part. For a typical sensor-fusion or motor-control loop running from Flash with zero-wait states, that translates to roughly 48 MIPS. 256 KB of Flash is enough for a moderate application stack: a FreeRTOS kernel, a CANopen or Modbus stack, plus the application logic. The 32 KB of SRAM supports a few hundred bytes of heap and stack per task. Rated from -40 to 105 °C, this MCU is specified for industrial environments. The STM32F091RCH7 carries an EOL hot lifecycle status, meaning STMicroelectronics has marked this part for end-of-life. Production is still active per the latest status entry, but the window for last-time-buy is closing.","metaTitle":"ST STM32F091RCH7 ARM Cortex-M0 MCU, 48 MHz, 256 KB Flash","metaDescription":"STMicroelectronics STM32F091RCH7 32-bit MCU, ARM Cortex-M0 at 48 MHz, 256 KB Flash, 32 KB RAM, 52 I/O, -40 to 105 °C.
