The flash wait state must be set to 1 before raising the core clock above 24 MHz, or the first branch after a reset will hard-fault. For designs that need deterministic response, the DMA and I²S peripherals offload data movement from the core. For dual-sourcing resilience, the base product number STM32F091 covers multiple density and package variants within the same family, so a pin-compatible upgrade path exists if future firmware needs more Flash or RAM. ## 48-UFQFN package — footprint and thermal management The Tape & Reel delivery (TR suffix) is the standard for automated pick-and-place assembly.","metaTitle":"STM32F091CCU6TR STM32F0 ARM Cortex-M0 MCU, 48 MHz","metaDescription":"STMicroelectronics STM32F091CCU6TR 32-bit MCU, ARM Cortex-M0 at 48 MHz, 256 KB Flash, 32K x 8 RAM, 13x12b ADC, 2x12b DAC, CANbus, -40°C to 85°C, 48-UFQFN.","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":"Tape & Reel (TR)","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":"$3.4437","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/eb815e3c1023a3c34c75039eeb7a4080.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32F091CCU6TR/alternatives.json"},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to STM32F091CCU6TR in this component family?","answer":"Within the STM32F091 base product number, the STM32F091RCT6 offers a larger 256 KB Flash and 48 KB SRAM in a 64-pin LQFP package — but it is not pin-compatible with the 48-UFQFN footprint.
