The device is supplied in a 49-ball WLCSP package (49-UFBGA, 49-WLCSP), a true chip-scale package that minimizes board area but requires controlled assembly processes — the 0.4 mm ball pitch and thin profile call for a well-tuned reflow profile and X-ray inspection after soldering. ## Peripherals and connectivity for compact embedded designs An internal oscillator is included, though for precise timing an external crystal or clock source is typically used.","metaTitle":"STM32F401CCY6BTR ARM Cortex-M4 MCU, 84MHz, 256KB Flash","metaDescription":"STM32F401CCY6BTR 32-bit ARM Cortex-M4 MCU from STMicroelectronics, 84MHz, 256KB Flash, 64KB SRAM, 49-WLCSP, active lifecycle.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"STMicroelectronics","Speed":"84MHz","Series":"STM32F4","Package":"Tape & Reel (TR)","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":"49-UFBGA, WLCSP","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 ~ 85°C (TA)","Supplier Device Package":"49-WLCSP","Voltage - Supply (Vcc/Vdd)":"1.7V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$48.8900","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/3f739c6e7b3a419d9a7183e4b2cf48ca.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32F401CCY6BTR/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy STM32F401CCY6BTR?","answer":"Submit a request for quotation to confirm current availability and pricing."},{"question":"What is the closest pin-compatible alternative to STM32F401CCY6BTR?","answer":"Within the STM32F401 series, pin-compatible WLCSP variants differ primarily in Flash and SRAM density.
