480 MHz Cortex-M7 — where it lands in the H7 line
The STM32H742AII6 is a 32-bit single-core ARM Cortex-M7 MCU from ST's STM32H7 series, clocked at 480 MHz. 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.
Package and board fit
The 169-UFBGA (7x7 mm) is a fine-pitch BGA — no hand-solder, needs a solder-paste stencil and reflow. The small footprint saves board area but routes out on a four-layer minimum.
Lifecycle and sourcing
The STM32H742AII6 is listed as active in production. It is sourced and quoted to order through independent distribution; availability and current pricing are confirmed at quote time.
