The STM32F765VGT7: The core runs at 216 MHz, backed by 1 MB of Flash and 512 KB of RAM. The 100-LQFP package gives access to 82 I/Os and the full connectivity set: Ethernet MAC, dual CAN, USB OTG, QSPI, SAI, SPDIF, and multiple UART/SPI/I²C interfaces.
Memory and peripheral fit for a single-chip architecture
The 512 KB SRAM is organised as 512K x 8 bits — enough for double-buffered Ethernet packets or a CANopen object dictionary. The QSPI interface lets you memory-map an external serial Flash or PSRAM for code shadowing or data logging, which is useful when the 1 MB Flash ceiling is tight.
The base product number STM32F765 covers multiple Flash and package variants, which gives some supply flexibility if a future BOM revision needs a different density or pin count within the same family.
Package and layout notes for the 100-LQFP
The internal oscillator can be used to save a crystal on cost-sensitive boards, though an external clock source will give tighter timing for Ethernet or USB.
