The ARM Cortex-M0 core runs at 48 MHz, which is the ceiling for this part. The 32-bit single-core architecture handles 8- and 16-bit data efficiently, so migrating from an older 8-bit design is straightforward. The 32 KB SRAM leaves room for a couple of moderate-size buffers — enough for a 128-byte CAN message queue or a 1 KB ADC sample buffer — without forcing external RAM. ## Integrated analog and connectivity Thirteen 12-bit ADC channels and two 12-bit DAC channels are on-chip, reducing the need for external analog front-end components in sensor and control-loop designs.","metaTitle":"STM32F091CCT6TR 32-bit MCU, 48 MHz, 256 KB Flash, 48-LQFP","metaDescription":"STMicroelectronics STM32F091CCT6TR ARM Cortex-M0 MCU, 48 MHz, 256 KB Flash, 32 KB RAM, 48-LQFP.
