On the peripheral side, the part includes USB OTG for direct host/peripheral switching, SDIO for external storage, three SPI and three I²C interfaces, plus a 10-channel 12-bit ADC. ## 84 MHz Cortex-M4 — where the speed matters The FPU accelerates sensor fusion and PID calculations without software emulation. For a motor-drive or digital-power design, the 84 MHz clock gives enough headroom to run a 20 kHz current loop with a few hundred microseconds left for communications and housekeeping. 256 KB of Flash supports a moderate application: a FreeRTOS kernel, a USB stack, a CANopen or Modbus library, and a few thousand lines of application code fit without squeezing. 64 KB of SRAM is the tighter resource — it limits buffering for USB mass-storage class or large audio buffers. If your application needs a 50 KB heap for JSON parsing or a 20 KB double-buffer for a camera sensor, the 64 KB ceiling forces careful allocation or an external SRAM. ## Industrial temperature and package — design-in notes The 7x7 mm body is hand-solderable with a hot-air station, but the fine 0.5 mm pitch calls for a good stencil and reflow profile — MSL 3 handling applies (bake before reflow if the moisture-barrier bag has been open beyond the floor-life window). ST continues to manufacture the STM32F4 series, and this density/package variant remains in the current portfolio.","metaTitle":"STM32F401CCU7 ARM Cortex-M4 MCU, 84 MHz, 256 KB Flash","metaDescription":"STMicroelectronics STM32F401CCU7 32-bit MCU with 84 MHz ARM Cortex-M4, 256 KB Flash, 64 KB SRAM, USB OTG, industrial temp -40°C to 105°C, in 48-UFQFPN package.","metaKeywords":null},"attributes":{"series":"STM32F4","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"STMicroelectronics","Speed":"84MHz","Series":"STM32F4","Package":"Tray","RAM Size":"64K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, DMA, I²S, POR, PWM, WDT","Connectivity":"I²C, IrDA, LINbus, SDIO, SPI, UART/USART, USB OTG","Mounting Type":"Surface Mount","Number of I/O":"36","Core Processor":"ARM® Cortex®-M4","Package / Case":"48-UFQFN Exposed Pad","Product Status":"Active","Data Converters":"A/D 10x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32F401","Program Memory Size":"256KB (256K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 105°C (TA)","Supplier Device Package":"48-UFQFPN (7x7)","Voltage - Supply (Vcc/Vdd)":"1.7V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.6100","priceTiers":[{"qty":1,"price":"$6.61000","currency":"USD"},{"qty":10,"price":"$5.97400","currency":"USD"},{"qty":25,"price":"$5.69640","currency":"USD"},{"qty":80,"price":"$4.94625","currency":"USD"},{"qty":230,"price":"$4.72400","currency":"USD"},{"qty":440,"price":"$4.30716","currency":"USD"},{"qty":1560,"price":"$3.75140","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/3f739c6e7b3a419d9a7183e4b2cf48ca.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32F401CCU7/alternatives.json"},"ai":{"faq":[{"question":"What is the maximum speed of STM32F401CCU7?","answer":"The core runs at 84 MHz, which is the maximum clock frequency for this device.
