280 MHz Cortex-M7 with a 1.4 MB SRAM buffer — what this MCU is built for
It carries 128 KB of Flash for code storage and a notably large 1.4 MB SRAM — a ratio that signals this part is designed for display-buffer, camera-frame, or data-acquisition roles where the working memory dwarfs the firmware footprint.
1.4 MB SRAM — the deciding spec for buffer-heavy designs
The 1.4 MB SRAM is the standout feature on this part. For a 128 KB Flash MCU, that much RAM is unusual — it tells you the application is expected to hold large frame buffers, look-up tables, or real-time data streams in SRAM rather than executing from external memory. The 280 MHz Cortex-M7 core can feed that RAM at full speed without wait-state penalties, which matters for display refresh or camera pixel pipelines. If your BOM needs an MCU that keeps a VGA or smaller LCD frame buffer on-chip and still has room for a double-buffered DMA ring, this part fits that profile.
The supply range of 1.62 V to 3.6 V covers both 1.8 V and 3.3 V logic rails, which simplifies dual-supply designs or battery-powered equipment running down to near-empty cells.
