If you are replacing a slower STM32F4 in a control loop, check that the peripheral timing and interrupt latency in your firmware don't assume a lower clock — the core will execute faster, which can break tight polling loops or delay compensation. The 82 I/O lines and the full connectivity set (CANbus, Ethernet, USB OTG, multiple SPI and I²C) mean it can drop into a communication-heavy design without re-spinning the board. ## Active lifecycle — no scramble for last-time buys The base product number is STM32F427, so if you ever need to cross-reference within the family, that is the anchor. The 100-LQFP (14x14 mm) is a standard footprint. No need for a pre-heater or hot-air station for a single swap — just good flux and steady hands. The Tape & Reel variant (this TR suffix) is the same die and package as the tray version; the only difference is the shipping medium, so your rework procedure is identical.","metaTitle":"STM32F427VIT6TR STM32F4 ARM Cortex-M4 MCU, 180MHz, 2MB Flash","metaDescription":"STM32F427VIT6TR 32-bit ARM Cortex-M4 MCU at 180MHz with 2MB Flash and 256K x 8 RAM.
