Technical 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.
