The 80K x 8 SRAM supports real-time data acquisition, stack-heavy DSP libraries, and multi-protocol communication stacks. For sensor-fusion or motor-control loops that demand fast context switching, the 72 MHz Cortex-M4 with single-cycle multiply-accumulate handles the arithmetic without stalling the bus. ## 100-WLCSP — footprint and assembly considerations This saves board area but demands tight PCB land-pattern tolerances and a controlled reflow profile. The 77 I/O count in this footprint gives good routing density for mixed-signal designs. MSL is typically 1 for WLCSP, but verify the specific moisture sensitivity level from the latest STM application note before opening the sealed reel. The base product number STM32F303 covers a broad family of density and package variants, ensuring long-term supply continuity for the platform.","metaTitle":"STM32F303VEY6TR ARM Cortex-M4 MCU, 72MHz, 512KB Flash, WLCSP","metaDescription":"STMicroelectronics STM32F303VEY6TR 32-bit ARM Cortex-M4 MCU at 72 MHz with 512 KB Flash, 80K x 8 RAM, industrial temp -40°C to 85°C, in 100-WLCSP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"STMicroelectronics","Speed":"72MHz","Series":"STM32F3","Package":"Tape & Reel (TR)","RAM Size":"80K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"DMA, I²S, POR, PWM, WDT","Connectivity":"CANbus, I²C, IrDA, LINbus, SPI, UART/USART, USB","Mounting Type":"Surface Mount","Number of I/O":"77","Core Processor":"ARM® Cortex®-M4","Package / Case":"100-UFBGA, WLCSP","Product Status":"Active","Data Converters":"A/D 39x12b; D/A 2x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32F303","Program Memory Size":"512KB (512K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"100-WLCSP (4.2x4.7)","Voltage - Supply (Vcc/Vdd)":"2V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$7.2956","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/c1aa05dbd335dffd091de829325705a6.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32F303VEY6TR/alternatives.json"},"ai":{"faq":[{"question":"How does STM32F303VEY6TR compare to STM32F303VCT6?","answer":"The STM32F303VCT6 is a sibling in the same STM32F3 family but typically offered in a larger LQFP-100 package rather than the WLCSP. The core, speed, Flash, and RAM are identical; the package difference is the primary deciding factor — the VEY6TR's WLCSP saves board area but requires more careful assembly handling."},{"question":"What is the lead time for STM32F303VEY6TR?","answer":"Lead time is confirmed at quote time through our independent distribution network.
