The 32-LQFP (7x7 mm) package is hand-solderable.
The supply voltage range is 1.71 V to 3.6 V, allowing direct battery operation and compatibility with common 3.3 V logic.
The primary difference is Flash memory size: the MKL04Z8VLC4 has 8 KB Flash, while the MKL04Z16VLC4 doubles that to 16 KB. Both share the same 48 MHz Cortex-M0+ core, 1 KB RAM, 28 I/O, and 32-LQFP package, making them pin-compatible alternatives for scaling firmware storage.
