It carries 2 MB of Flash and 692 KB of RAM on a 169-ball UFBGA (7x7 mm) package. ## Memory and I/O — what the 2 MB / 692 KB buys you The 2 MB Flash is enough for a full graphics stack or a multi-protocol communication gateway without external memory. The 692 KB RAM handles large audio buffers or real-time control loops. With 131 I/O lines and connectivity including Ethernet, dual CAN, USB OTG, and QSPI, this part can serve as a system controller that talks to sensors, displays, and a host processor simultaneously. The 36-channel 16-bit ADC and dual 12-bit DAC cover analog front-end duties on the same die. The 169-UFBGA (7x7 mm) is a fine-pitch BGA — no hand-solder, needs a solder-paste stencil and reflow.","metaTitle":"ST STM32H742AII6 ARM Cortex-M7 MCU, 480 MHz, 2 MB Flash, 169-UFBGA","metaDescription":"STMicroelectronics STM32H742AII6 32-bit MCU, 480 MHz Cortex-M7 core, 2 MB Flash, 692 KB RAM, 131 I/O, industrial temp -40°C to 85°C.
