For a design that requires both a color TFT display and a wired network connection — common in operator panels, smart meters, or test equipment — this eliminates the cost and board area of a separate Ethernet controller or display driver IC. The 180 MHz Cortex-M4 has enough headroom to run a lightweight TCP/IP stack and refresh the display buffer without stalling the control loop. The ROHS3 compliance covers current European and global regulatory requirements without an exemption expiry to track.","metaTitle":"STM32F439VIT6 STM32F4 MCU, 180 MHz, 2 MB Flash, 100-LQFP","metaDescription":"STM32F439VIT6 ARM Cortex-M4 MCU at 180 MHz with 2 MB Flash, 256K RAM, Ethernet, LCD, 16x12b ADC.
