The tray shipping medium means the parts arrive in a rigid carrier; plan for pick-and-place handling with a dedicated BGA nozzle.","metaTitle":"STM32F439IIH6 ARM Cortex-M4 MCU, 180 MHz, 2 MB Flash","metaDescription":"STMicroelectronics STM32F439IIH6 32-bit ARM Cortex-M4 MCU at 180 MHz with 2 MB Flash and 256 KB RAM. 140 I/O, Ethernet, USB OTG, CAN.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Speed":"180MHz","title":"STM32F439IIH6","Series":"STM32F4","Package":"Tray","RAM Size":"256K x 8","Core Size":"32-Bit Single-Core","Peripherals":"Brown-out Detect/Reset, DMA, I²S, LCD, POR, PWM, WDT","Connectivity":"CANbus, EBI/EMI, Ethernet, I²C, IrDA, LINbus, SPI, UART/USART, USB OTG","Mounting Type":"Surface Mount","Number of I/O":"140","Core Processor":"ARM® Cortex®-M4","Package / Case":"201-UFBGA","Data Converters":"A/D 24x12b; D/A 2x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32F439","Program Memory Size":"2MB (2M x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"176+25UFBGA (10x10)","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$22.1700","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/7ccff475f92d57ddcb2c7509216e5655.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32F439IIH6/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between STM32F439IIH6 and STM32F439NIH6?","answer":"The difference is the package. STM32F439IIH6 comes in a 201-UFBGA (176+25 balls, 10x10 mm), while STM32F439NIH6 uses a 216-TFBGA. Both carry the same core, memory, and peripheral set — the package choice drives PCB footprint and rework process, not functional capability."},{"question":"Can STM32F439IIH6 be used as a replacement for STM32F429IIH6?","answer":"Yes, the STM32F439IIH6 is pin-compatible with the STM32F429IIH6 in the same 201-UFBGA package. The F439 adds a hardware cryptographic accelerator and a true random number generator (TRNG) that the F429 lacks. If your firmware does not use those blocks, the F439 drops in as a direct replacement with no board change."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM32F439IIH6","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM32F439IIH6 when reusing this data.
