The peripheral set includes CANbus, multiple I²C and SPI interfaces, UART/USART with IrDA and LIN support, plus a 12-bit ADC with 19 channels and a 2-channel 12-bit DAC. The supply range spans 2V to 3.6V, so it runs from a single 3.3V rail or a 2-cell Li-ion pack without a regulator. Housed in a 64-UFBGA (5x5 mm) package, this is a fine-pitch BGA. The supplier device package is 64-UFBGA (5x5).","metaTitle":"STM32F091RCH6 ARM Cortex-M0 MCU, 48MHz, 256KB Flash","metaDescription":"STMicroelectronics STM32F091RCH6 32-bit MCU with 48MHz ARM Cortex-M0 core, 256KB Flash, 32K x 8 RAM, 52 I/O, CANbus, 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":"52","Core Processor":"ARM® Cortex®-M0","Package / Case":"64-UFBGA","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~85°C(TA)","Supplier Device Package":"64-UFBGA (5x5)","Voltage - Supply (Vcc/Vdd)":"2V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.5697","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/eb815e3c1023a3c34c75039eeb7a4080.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32F091RCH6/alternatives.json"},"ai":{"faq":[{"question":"What is the maximum clock speed of STM32F091RCH6?","answer":"The core runs at 48MHz maximum, driven by an internal oscillator or an external clock source. At 48MHz the Flash requires one wait state for zero-wait access; the Cortex-M0 pipeline handles most single-cycle instructions at that speed."},{"question":"What is the difference between STM32F091RCH6 and STM32F091RCT6?","answer":"The two parts share the same core, memory, and peripheral set. The key difference is the package: the RCH6 comes in a 64-UFBGA (5x5 mm) fine-pitch BGA, while the RCT6 uses a 64-LQFP (10x10 mm) gull-wing package. The LQFP variant is easier to hand-solder and inspect; the BGA saves board area but requires reflow assembly."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM32F091RCH6","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM32F091RCH6 when reusing this data.
