The 48 MHz clock rate is the practical ceiling for this core — firmware that needs tight loop timing or fast peripheral response should budget for the 1-cycle flash wait state at that speed. The 256 KB Flash is generous for the STM32F0 family, leaving room for a bootloader, application code, and a small OTA staging area. With 52 I/O lines and a rich peripheral set including CANbus, I²C, SPI, and multiple UART/USART channels, this MCU can serve as the central controller in a distributed control node or gateway. ## Industrial temperature grade and environment The 105°C upper limit provides margin above the typical 85°C industrial ceiling, which matters when the MCU sits near a power stage or in a sealed enclosure with limited airflow. ## Peripheral integration: CANbus and analog converters The STM32F091RCT7 includes a CANbus interface (supporting CAN 2.0B), which is a key differentiator versus many Cortex-M0 parts that omit CAN. The ADC can sample multiple channels in sequence without CPU intervention using the DMA controller, freeing the core for higher-level tasks.","metaTitle":"STM32F091RCT7 ARM Cortex-M0 MCU, 48 MHz, 256 KB Flash","metaDescription":"STMicroelectronics STM32F091RCT7 32-bit MCU with ARM Cortex-M0 core at 48 MHz, 256 KB Flash, 32K x 8 RAM, CANbus, 12-bit ADC/DAC, -40°C to 105°C.","metaKeywords":null},"attributes":{"series":"STM32F0","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"STMicroelectronics","Speed":"48MHz","Series":"STM32F0","Package":"Tray","RAM Size":"32K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"DMA, I²S, POR, PWM, WDT","Connectivity":"CANbus, I²C, IrDA, LINbus, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"52","Core Processor":"ARM® Cortex®-M0","Package / Case":"64-LQFP","Product Status":"Active","Data Converters":"A/D 19x12b; D/A 2x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32F091","Program Memory Size":"256KB (256K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~105°C(TA)","Supplier Device Package":"64-LQFP (10x10)","Voltage - Supply (Vcc/Vdd)":"2V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$7.1300","priceTiers":[{"qty":1,"price":"$7.13000","currency":"USD"},{"qty":10,"price":"$6.43800","currency":"USD"},{"qty":25,"price":"$6.13920","currency":"USD"},{"qty":80,"price":"$5.33050","currency":"USD"},{"qty":230,"price":"$5.09087","currency":"USD"},{"qty":440,"price":"$4.64168","currency":"USD"},{"qty":960,"price":"$4.08360","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/eb815e3c1023a3c34c75039eeb7a4080.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32F091RCT7/alternatives.json"},"ai":{"faq":[{"question":"What are the best alternatives or equivalents for STM32F091RCT7?","answer":"The STM32F091RCT7 offers higher speed, more I/O, and a wider temperature range, making it the better fit for industrial control where throughput and environmental margin matter."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM32F091RCT7","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM32F091RCT7 when reusing this data.
