The STM32F765ZGT6TR runs at 216 MHz with 1 MB Flash and 512 KB SRAM. It has 114 I/O pins and peripherals including Ethernet, dual CAN, USB OTG, QSPI, SAI, and multiple SPI/I²C/UART.
The 144-LQFP package (20x20 mm body) is a hand-solderable, inspectable footprint — no BGA rework station needed, which matters for prototype turns and low-volume production.
For a production BOM, this removes the obsolescence risk that haunts older MCU families.
Memory and data converter headroom
1 MB of Flash (1M x 8) is enough for a full-featured firmware image with a bootloader, application code, and a small file system. The 512 KB SRAM (512K x 8) handles multiple protocol buffers, a display frame buffer at VGA resolution, or a real-time control loop's data arrays without external SRAM. On the analog side, the MCU integrates 24 analog-to-digital converters (12-bit each) and two 12-bit digital-to-analog converters — enough for multi-channel sensor acquisition or closed-loop analog output without an external ADC/DAC.
