The Cortex-M0 core keeps the toolchain simple — same ARM GCC/Keil/IAR ecosystem as the rest of the STM32 lineup, but with a smaller gate count than the M3/M4 siblings, which helps keep the BOM cost down for high-volume industrial and consumer gear. The 48 MHz clock is the ceiling for this part — no PLL multiplication beyond that. If your application needs a 72 MHz core or a floating-point unit, you are looking at the STM32F1 or STM32F3 series instead. For most sensor fusion, motor control loops, or CAN/I²C/SPI bridge tasks, 48 MHz is enough headroom without over-specifying the silicon. ## 48-UFQFN with exposed pad — rework and layout notes Package is a 48-lead UFQFN with an exposed pad (7x7 mm body). The exposed pad also serves as the main ground return for the core, so a solid solder joint there is critical. On a rework station, hot air at 300 °C with a fine nozzle works; just pre-bake the board if the moisture-sensitive level (MSL 3) floor life has been exceeded. The 48-UFQFPN footprint matches the STM32F0 Discovery board's layout, so you can prototype with a Nucleo-F091RC or similar and then drop this part onto the production board with minimal signal re-routing. ## Analog peripherals — 13-channel ADC and dual DAC Thirteen 12-bit ADC channels and two 12-bit DAC channels are on-chip. That is enough for a three-phase current-sense plus a couple of voltage monitors without adding external ADCs. The DACs are useful for generating analog setpoints or audio-level outputs. That covers most industrial fieldbus and sensor interfaces without extra transceivers (except CAN, which still needs an external transceiver). The DMA engine offloads the Cortex-M0 during high-rate data transfers — useful when streaming ADC samples or shuttling UART packets without stalling the core. With 37 I/O lines in the 48-pin package, you get enough GPIO for a small keypad, LED indicators, and a parallel LCD interface if needed, though the pin count is tight for a full 16-bit parallel bus. ST lists the STM32F098CCU6 as an active product. For dual-sourcing resilience, the STM32F098C8T6 (same core, 64 KB Flash, LQFP-48) is a pin-compatible drop-in if your firmware fits the smaller Flash; otherwise, the STM32F098CCU6 is the higher-density option in the same package.","metaTitle":"STM32F098CCU6 ARM Cortex-M0 MCU, 48 MHz, 256 KB Flash","metaDescription":"STMicroelectronics STM32F098CCU6 32-bit MCU with ARM Cortex-M0 core, 48 MHz, 256 KB Flash, 32 KB RAM, 13-ch 12-bit ADC, 2-ch 12-bit DAC, CAN, I²C, SPI","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":"37","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":"STM32F098","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)":"1.65V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.4070","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/0a760a55ca4ba604cdd43006167143a4.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32F098CCU6/alternatives.json"},"ai":{"faq":[{"question":"Is STM32F098CCU6 an active part or nearing end of life?","answer":"ST's product status is Active. No end-of-life notifications are published for this base number. It is safe to design into new production runs without an immediate LTB risk."},{"question":"Does STM32F098CCU6 have internal EEPROM?","answer":"The evidence does not list an EEPROM size for this part. The program memory is 256 KB of Flash. If you need non-volatile storage for calibration or configuration data, you will either reserve a Flash sector (with wear-leveling) or add an external serial EEPROM."},{"question":"What is the maximum operating frequency and core architecture of STM32F098CCU6?","answer":"The core is a 32-bit ARM Cortex-M0 running at up to 48 MHz. That is the maximum clock — no PLL multiplication beyond that figure."},{"question":"What is the difference between STM32F098CCU6 and STM32F098C8T6?","answer":"Both share the same Cortex-M0 core at 48 MHz and the same peripheral set, but the C8T6 has 64 KB of Flash versus 256 KB on the CCU6, and it comes in an LQFP-48 package instead of UFQFN-48. The LQFP is easier to hand-solder and inspect; the UFQFN saves board area. If your firmware fits in 64 KB and you prefer a leaded package, the C8T6 is a direct alternative."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM32F098CCU6","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM32F098CCU6 when reusing this data.
