Product details

480 MHz Cortex-M7 — what that buys the design

That core speed, combined with 2 MB of Flash and 1 MB of RAM, puts it in the performance tier for DSP-heavy or real-time control tasks — motor drives, active filtering, or audio processing — where a lower-speed Cortex-M3 or M4 would run out of headroom.

The package is a 176+25 UFBGA (10x10 mm), a fine-pitch BGA with 201 balls. That's not a hand-solderable part — you'll need a reflow oven, stencil, and X-ray inspection. If your production line isn't set up for BGAs, this part will add assembly cost. The supply voltage range is 1.62 V to 3.6 V, giving flexibility for both 1.8 V and 3.3 V logic rails.

Frequently asked questions

What is the maximum clock speed of STM32H753IIK6?

The core runs at 480 MHz, which is the headline speed for this STM32H7 part. That clock rate, combined with the Cortex-M7's dual-issue pipeline and FPU, delivers the throughput for real-time control and signal processing tasks that a 32 MHz Cortex-M3 (like the STM32L151CBU6A) cannot match.

What is the flash memory size of STM32H753IIK6?

It has 2 MB of Flash (2M x 8), which is generous for a single-chip MCU. That's enough for a full RTOS, a TCP/IP stack, a GUI library, and application code without needing external serial Flash.
