The NXP MKL02Z16VFG4R is a 32-bit ARM Cortex-M0+ microcontroller running at 48 MHz with 16 KB Flash and 2 KB RAM.
The 48 MHz Cortex-M0+ core can poll sensors and run a serial protocol without an external co-processor, but the 16 KB Flash and 2 KB RAM limit firmware size. A design needing more than a single control loop and a small state machine will exceed this part.
The datasheet is published by NXP under the base product number MKL02Z16. It covers the full KL02 family electrical characteristics, pinout, and application notes.
Yes, the supply range of 1.71 V to 3.6 V means the part operates at 3.3 V and its I/O are 3.3 V tolerant.
The MKL02Z32VFG4R is a pin-compatible sibling with 32 KB Flash instead of 16 KB. The MKL02Z16VFG4R can replace it only if the firmware fits within 16 KB.
