The 12 KB RAM (organized as 12K x 8) is tight for buffered communication stacks; budget carefully if you plan to use multiple UART or SPI channels with large packet queues. ## Peripherals and connectivity — what is on-chip The oscillator is internal, so you can save a crystal on the BOM if the application tolerates the internal accuracy. ## 108-ball BGA — layout and rework considerations That is a 108-LFBGA package (10x10 mm).
