The package has no exposed thermal pad; heat dissipation relies on the PCB copper plane and via stitching under the BGA. On-chip peripherals include DMA, PWM, WDT, I²S, and POR/Brown-out detect. The connectivity block covers CANbus, Ethernet, USB OTG, and an external memory interface (EBI/EMI) that can handle SRAM, NOR Flash, or NAND Flash. This peripheral mix suits applications like industrial PLCs, motor drives with encoder feedback, and IoT gateways that aggregate sensor data and push it over Ethernet or CAN.","metaTitle":"STM32F427IIH6 STM32F4 MCU, 180 MHz ARM Cortex-M4, 2 MB Flash","metaDescription":"STM32F427IIH6 32-bit MCU with 180 MHz ARM Cortex-M4, 2 MB Flash, 256 KB SRAM, 140 I/O, Ethernet, CAN, USB OTG.

Both share the same 180 MHz Cortex-M4 core, 2 MB Flash, 256 KB SRAM, 176-ball UFBGA package, and peripheral set (Ethernet, CAN, USB OTG). If your design drives a parallel RGB display, the F429 is the fit; for headless or serial-interface displays, the F427 saves cost."},{"question":"Can STM32F427IIH6 replace STM32F427VITx?","answer":"The STM32F427VITx is a 100-pin LQFP variant of the same die; the STM32F427IIH6 is a 176-ball UFBGA variant. The core, memory, and peripheral set are identical, but the pinout and package differ. A board redesign is required to swap between them — they are not drop-in compatible. The IIH6 offers more I/O (140 vs 82 on the VITx) and a smaller footprint."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM32F427IIH6","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM32F427IIH6 when reusing this data.
