What the 72 MHz core and memory mean for your BOM
72 MHz core runs a Modbus RTU stack, PID loops, or a small TFT display without external RAM. 32 KB Flash suits firmware for a sensor node or simple motor controller.
Connectivity and peripherals for control applications
On-chip peripherals include I2C, SPI, UART/USART, and SSI — enough for sensor interfaces, serial displays, and simple fieldbus gateways. The brown-out detect and watchdog timer are standard for industrial reliability: the BOD resets the MCU cleanly if the supply dips below the threshold, and the WDT prevents lockups in unattended equipment. The internal oscillator means you can run without an external crystal for non-critical timing, saving two pins and a component.
