The 13-channel 12-bit ADC and 2-channel 12-bit DAC reduce the need for external analog front-end components in control-loop and sensor-fusion applications. Internal oscillator support eliminates an external crystal in less timing-critical designs, though the PLL still needs a clean reference for 48 MHz operation. ## Package and thermal — 48-UFQFPN exposed pad The base product number STM32F091 covers multiple Flash and pin-count variants, so cross-referencing the full order code is essential for fit.","metaTitle":"STM32F091CCU6 ARM Cortex-M0 MCU, 48 MHz, 256 KB Flash","metaDescription":"STMicroelectronics STM32F091CCU6 32-bit MCU, 48 MHz ARM Cortex-M0, 256 KB Flash, 32 KB SRAM, CANbus, I2C, 12-bit ADC/DAC, -40 to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"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":"38","Core Processor":"ARM® Cortex®-M0","Package / Case":"48-UFQFN Exposed Pad","Product Status":"Active","Data Converters":"A/D 13x12b; 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 ~ 85°C (TA)","Supplier Device Package":"48-UFQFPN (7x7)","Voltage - Supply (Vcc/Vdd)":"2V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.1400","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/eb815e3c1023a3c34c75039eeb7a4080.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32F091CCU6/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy STM32F091CCU6 available via RFQ confirmation?","answer":"STM32F091CCU6 is available to order through independent distribution.

No end-of-life notice has been issued, so it remains qualified for new designs and volume production."},{"question":"What is the closest pin-compatible alternative to STM32F091CCU6?","answer":"Within the STM32F0 series, the STM32F091RCT6 is a close functional match but has a different pin count and package (64-pin LQFP). For a pin-compatible drop-in, look at other 48-UFQFPN variants in the STM32F091 line — verify the Flash and SRAM sizes against your firmware footprint."},{"question":"What is STM32F091CCU6's listed speed?","answer":"The core runs at 48 MHz maximum, which is the ceiling for the ARM Cortex-M0 in this STM32F0 part.
