Product details

That clock rate, combined with 2 MB of Flash and 256K x 8 of SRAM, gives it headroom for real-time control loops, sensor fusion, and protocol stacks that would stress a lower-end part. The 100-LQFP package (14x14 mm) exposes 82 I/O, so you can route a parallel display, a memory bus, or a sensor array without multiplexing.

Peripheral set — Ethernet, CAN, and the external bus

This part includes Ethernet MAC, CAN 2.0B, USB OTG, and an external memory interface (EBI/EMI) alongside the usual I²C, SPI, UART/USART, I²S, and IrDA. The EBI/EMI lets you attach parallel SRAM, NOR Flash, or an FPGA without a glue-logic CPLD, which simplifies the board layout for an HMI or datalogger.

It is not AEC-Q100 qualified, so it is not a direct fit for under-hood automotive or aerospace without additional screening.

ROHS3 compliant.

Frequently asked questions

What is the difference between STM32F427VIT6 and STM32F427VGT6?

The VIT6 and VGT6 share the same core, Flash, and RAM. The suffix difference typically indicates package or temperature variant — VIT6 is the 100-LQFP industrial-temperature version. The VGT6 may be a different package or grade; check the exact suffix against the STM32F427 ordering code table for full detail.
