The 169-UFBGA package (7×7 mm) packs 114 I/O. ## Connectivity and data converter complement Carries an Ethernet MAC (MII/RMII), two CAN 2.0B interfaces, USB OTG HS/FS, six SPI ports, three I²C, and an external memory interface (EBI/EMI). On the analog side there are 24 multiplexed 12-bit ADC channels and two 12-bit DACs. Active product status removes the obsolescence risk that haunts older parts, but the 169-UFBGA package is a single-source footprint — there is no pin-compatible second source from another vendor.","metaTitle":"STM32F439AIH6 STM32F4 ARM Cortex-M4 MCU, 180 MHz, 2 MB Flash","metaDescription":"STMicroelectronics STM32F439AIH6 32-bit ARM Cortex-M4 MCU at 180 MHz with 2 MB Flash, 256 KB RAM, Ethernet MAC, CAN, USB OTG, 169-UFBGA.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Speed":"180MHz","title":"STM32F439AIH6","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":"114","Core Processor":"ARM® Cortex®-M4","Package / Case":"169-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":"169-UFBGA (7x7)","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$11.9279","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/7ccff475f92d57ddcb2c7509216e5655.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32F439AIH6/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between STM32F439AIH6 and STM32F429AIH6?","answer":"The primary difference is the core clock speed: the STM32F439AIH6 runs at 180 MHz, while the STM32F429AIH6 is limited to 168 MHz. Both share the same 169-UFBGA package, 2 MB Flash, 256 KB RAM, and peripheral set including Ethernet MAC, so they are pin-compatible and can be swapped on the same board layout if the firmware PLL configuration is updated for the higher clock."},{"question":"Does STM32F439AIH6 have a built-in Ethernet MAC?","answer":"Yes, the STM32F439AIH6 integrates a full Ethernet MAC with dedicated DMA, supporting both MII and RMII interfaces."},{"question":"What development tools support STM32F439AIH6?","answer":"The STM32F439AIH6 is supported by the full STM32CubeIDE toolchain, including the HAL and LL driver libraries, plus middleware for USB, TCP/IP (LwIP), and graphics (TouchGFX). Third-party IDEs from IAR (EWARM) and Keil (MDK-ARM) also support this device. Debug access is through the standard SWD or JTAG interface on the 20-pin Cortex debug connector."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM32F439AIH6","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM32F439AIH6 when reusing this data.
