It carries 2 MB of Flash program memory and 256 KB of SRAM, enough to run a full Ethernet stack, a graphical LCD interface, and real-time control loops without external memory. Connectivity includes Ethernet, CAN, USB OTG, multiple SPI/I²C/UART, and an EBI/EMI bus for parallel peripherals. The 114 GPIOs and integrated LCD controller let it drive a display and handle fieldbus traffic simultaneously. The 143-ball WLCSP package (4.52 x 5.55 mm) saves board area but requires careful PCB layout — fine-pitch BGA with no peripheral leads. Plan for controlled solder paste stencil and underfill if the assembly sees vibration or thermal cycling. For dual-sourcing resilience, the base product number STM32F439 covers multiple package and temperature variants. A second source within the same family is not listed in the official cross-reference; procurement should qualify a pin-compatible STM32F4 sibling through ST's own documentation. ## Sourcing and compliance note RoHS compliance is standard for this STM32F4 series; full REACH and conflict-minerals declarations are available from the manufacturer upon request.","metaTitle":"ST STM32F439ZIY6TR ARM Cortex-M4 MCU, 180 MHz, 2 MB Flash","metaDescription":"STMicroelectronics STM32F439ZIY6TR 32-bit MCU, 180 MHz Cortex-M4, 2 MB Flash, 256 KB RAM, WLCSP-143, -40 to 85 °C.
