16 MHz core, 8 KB Flash — what the memory budget buys
The 512-byte RAM limits data buffers and call depth — plan for register-based variable storage and lean interrupt handlers.
No external level translator is needed for 1.8 V logic peripherals. The 28-TSSOP package (4.40 mm width) is a compact surface-mount footprint suited for space-constrained PCBs.
Serial interfaces and analog — peripheral set at a glance
That covers sensor readout (I²C/SPI), legacy UART links, and basic automotive LIN nodes.
