The 20 KB SRAM (20K x 8) is tight for a full TCP/IP stack but comfortable for a sensor fusion loop, a Modbus RTU slave, or a BLE host controller. ## Peripherals and connectivity for sensor and control applications The peripheral set includes brown-out detect, POR, DMA, I²S, PWM, and a watchdog timer. The 15-channel 12-bit ADC handles analog inputs like thermistors, strain gauges, or battery voltage monitoring without an external converter. ## 64-TFBGA — board assembly and footprint considerations Surface-mount only — no socket option for prototyping without an adapter board.
