The STM32F412 family has broad second-source availability through ST's own distribution network; no pin-compatible second-source from another vendor is documented in the ST cross-reference.","metaTitle":"STM32F412REY6TR STM32F4 ARM Cortex-M4 MCU, 100MHz","metaDescription":"STMicroelectronics STM32F412REY6TR 32-bit ARM Cortex-M4 MCU, 100MHz, 512KB Flash, 256KB SRAM, industrial temp -40 to 85°C, 64-WLCSP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"STMicroelectronics","Speed":"100MHz","Series":"STM32F4","Package":"Tape & Reel (TR); Cut Tape (CT)","RAM Size":"256K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, DMA, I²S, LCD, POR, PWM, WDT","Connectivity":"CANbus, EBI/EMI, I²C, IrDA, LINbus, MMC/SD/SDIO, QSPI, SPI, UART/USART, USB OTG","Mounting Type":"Surface Mount","Number of I/O":"50","Core Processor":"ARM® Cortex®-M4","Package / Case":"64-UFBGA, WLCSP","Product Status":"Active","Data Converters":"A/D 16x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32F412","Program Memory Size":"512KB (512K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"64-WLCSP (3.62x3.65)","Voltage - Supply (Vcc/Vdd)":"1.7V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$10.5200","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/7ff8656eb9f4bbf63345b4dad9fe308f.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32F412REY6TR/alternatives.json"},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to STM32F412REY6TR?","answer":"Within the STM32F412 family, the base product number STM32F412 covers multiple Flash/SRAM density options in the same 64-WLCSP footprint. The STM32F412RET6 (LQFP-64) is a common through-hole alternative but uses a different package — not pin-compatible with the WLCSP. For a WLCSP drop-in, compare the STM32F412CEY6 (512 KB Flash, 128 KB SRAM) or STM32F412VEY6 (1 MB Flash, 256 KB SRAM) if the memory budget differs.
