STM32H743IIK6

STM32H743IIK6 is a STMicroelectronics high-performance 32-bit microcontroller built on the Arm Cortex-M7 core with double-precision FPU running at up to 480 MHz, with 2 Mbytes of Flash, 1 Mbyte of RAM and the Art Accelerator in a UFBGA 176+25 package. Its advantage is headroom: 1027 DMIPS-class compute, 192 Kbytes of TCM RAM for time-critical routines, dual-mode Quad-SPI plus a flexible external memory controller, and up to 35 communication interfaces including FD-CAN, USB high-speed and Ethernet, so one MCU covers control, connectivity and display-class workloads that would otherwise need two chips. Three independent power domains, 1.62 to 3.6 V supply and scalable low-power modes keep it viable in both performance and battery-aware industrial designs. Selection advice: the II density code (2 Mbytes Flash) and K6 package code (UFBGA 176+25, 10 x 10 mm, 0.65 mm pitch) must both match your BOM — the same die ships in LQFP-176 (IIT6) and other packages that are not footprint-compatible, and the I versus G temperature/flash variants differ; if your application needs hardware crypto or a JPEG codec, step up to the STM32H753II, and if 2 Mbytes is more Flash than your firmware needs, the STM32H743VG-class 1 Mbyte parts cut cost.
