The STM32H742AGI6 is a 32-bit ARM Cortex-M7 MCU from ST's STM32H7 series, clocked at 480 MHz and built for high-bandwidth control and signal-processing tasks. It carries 1 MB of Flash and 692K x 8 of RAM, with a rich peripheral set that includes Ethernet, USB OTG, multiple CANbus interfaces, and a 36-channel 16-bit ADC.
480 MHz Cortex-M7 — what the clock buys you
The 480 MHz core speed on this single-core Cortex-M7 sustains real-time control loops and DSP-style math without an external coprocessor.
EOL hot — sourcing reality for the STM32H742AGI6
The lifecycle stage for this part is marked eol_hot, meaning ST has issued an end-of-life notice. The product status remains listed as Active.
Connectivity and I/O — Ethernet, USB OTG, and 131 GPIOs
With 131 I/O lines available, it can drive a parallel LCD via the EBI/EMI interface or connect to external memory and FPGA-style peripherals. The 36-channel 16-bit ADC and dual 12-bit DAC cover analog front-end needs without an external converter on many designs.
Package and mounting — 169-UFBGA (7x7)
The 169-UFBGA package measures 7x7 mm, a compact ball-grid array suited for surface-mount assembly on multi-layer PCBs. The fine pitch requires careful PCB layout for signal integrity, especially when routing the Ethernet and USB differential pairs.
