Program memory is 2 MB of Flash, sized for a full Ethernet TCP/IP stack, a FreeRTOS kernel, and a graphical LCD framebuffer without external memory. The 256 KB SRAM supports double-buffered DMA transfers between the Ethernet MAC and the LCD controller, so the core is not stalled by peripheral data movement. Connectivity includes Ethernet MAC, two CAN interfaces, USB OTG, multiple SPI and I²C buses, and an EBI/EMI memory controller for external SRAM or NAND Flash. The 114 general-purpose I/Os are enough to interface a parallel TFT display, a keypad matrix, and a dozen sensors without an I/O expander. ## 24 analog inputs and dual DACs — what the converter specs mean for signal chain accuracy The internal oscillator handles UART and I²C timing. For the ADC clock, an external crystal with PLL is recommended. ## Package and temperature grade — deployment fit","metaTitle":"STMicroelectronics STM32F439ZIT6 ARM Cortex-M4 MCU, 180MHz","metaDescription":"STM32F439ZIT6: 32-bit ARM Cortex-M4 MCU at 180 MHz with FPU/DSP, 2 MB Flash, 256 KB RAM, Ethernet, CAN, USB OTG, 24x12b ADC, -40 to 85°C, 144-LQFP.
