48 MHz Cortex-M0+ — what the speed buys you
The MKL16Z64VFT4R: The ARM Cortex-M0+ core runs at 48 MHz.
Temperature range and supply — where it fits
The 48-VFQFN exposed pad package measures 7×7 mm.
Peripherals and I/O — what's on the bus
The integrated 16-bit ADC and 12-bit DAC cover analog sensing and control without an external converter. Brown-out detect, low-voltage detect, and power-on reset are built in, so external supervisor ICs aren't needed for basic supply monitoring. The touch-sensing interface (TSI) is a differentiator for capacitive-touch panels or proximity switches — no separate controller required.
