The WLCSP package has a 0.4 mm ball pitch typically, so the PCB requires via-in-pad or microvia capability for routing. No end-of-life notification, no last-time-buy window. If dual-sourcing is a concern, the STM32F3 series includes pin-compatible siblings with different Flash/RAM or package options — ST's product-change notification (PCN) process applies if any variant shifts status.","metaTitle":"STM32F383RCY6TR STM32F3 ARM Cortex-M4F MCU, 72 MHz","metaDescription":"STM32F383RCY6TR 32-bit MCU from STMicroelectronics STM32F3 series.","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":"32K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"DMA, POR, PWM, WDT","Connectivity":"CANbus, HDMI-CEC, I²C, IrDA, LINbus, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"51","Core Processor":"ARM® Cortex®-M4F","Package / Case":"66-UFBGA, WLCSP","Product Status":"Active","Data Converters":"A/D 16x12b, 21x16b; D/A 3x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32F383","Program Memory Size":"256KB (256K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"66-WLCSP (3.8x4.2)","Voltage - Supply (Vcc/Vdd)":"1.65V ~ 1.95V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$10.9900","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/661479f35134f36a40f9b343b219aeb5.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32F383RCY6TR/alternatives.json"},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to the STM32F383RCY6TR?","answer":"Within the STM32F383 series, the base product number STM32F383 shares the same pinout and package across Flash and RAM density options.
