The 18-channel 16-bit ADC and one 12-bit DAC are on-chip, so a single-board design can digitise multiple analog inputs without an external multiplexer or a separate DAC.
The 48-QFN (7×7 mm) exposed pad package gives 40 I/O lines in a compact footprint. Surface-mount assembly is standard; no special reflow profile beyond the lead-free solder joint requirements.
Listed as Active.
The core runs at 48 MHz. That clock rate, combined with the single-cycle multiply on the Cortex-M0+, delivers enough throughput for most control and data-acquisition loops without a cache.
