The NXP MKL16Z256VLH4R is a 32-bit ARM Cortex-M0+ microcontroller from the Kinetis KL1 series, clocked at 48 MHz with 256 KB Flash and 32 KB RAM.
Rated from -40°C to 105°C, this MCU operates with a 1.71 V to 3.6 V supply range and provides 54 I/O lines in a 64-LQFP package.
Within the Kinetis KL1 family, pin-compatible density options include the MKL16Z128VLH4 (128 KB Flash) and MKL16Z64VLH4 (64 KB Flash) — same 64-LQFP footprint, same peripheral set. For a step up in performance, the KL2 series (72 MHz, FPU) shares the pinout but requires a firmware port for the different core.
