It carries 2 MB of Flash and 384 KB of SRAM, enough to run a GUI framework like TouchGFX or emWin directly, with room for a TCP/IP stack and application code. The 131 I/Os in a 176-LQFP package give you the pin count to drive a parallel RGB LCD, an external memory bus (EBI/EMI), and still have Ethernet, dual CAN, and USB OTG available.
180 MHz Cortex-M4 with FPU — where the speed matters
The 180 MHz core with hardware FPU and DSP instructions handles real-time control loops and floating-point math without a separate DSP. For an HMI panel running a 480x272 display with touch, the Chrom-ART Accelerator (DMA2D) offloads pixel blending and image copy from the CPU, so the 180 MHz budget goes to protocol handling and application logic rather than frame-buffer management.
Memory sizing for display and connectivity stacks
2 MB of Flash stores a full GUI library, font data, and the application binary without external Flash. The 384 KB SRAM splits between a frame buffer (a 480x272 16-bit display needs about 260 KB) and stack/heap for Ethernet and USB buffers. If the design needs more RAM, the EBI/EMI interface on this package variant connects to external SRAM or SDRAM without a glue-logic CPLD.
STMicroelectronics lists the STM32F469IIT6 as Active product status. This is a current-production part with no announced discontinuation or last-time-buy window. The STM32F469 series continues to receive firmware library updates and errata support from ST.
The 176-LQFP (24x24 mm) is a standard quad flat pack with 0.5 mm pitch, hand-solderable and inspectable.
