The NXP MKL14Z64VLH4 is a 32-bit ARM Cortex-M0+ MCU from the Kinetis KL1 series, clocked at 48 MHz with 64 KB Flash and 8 KB RAM.
64 KB of program Flash and 8 KB of SRAM place this MCU in the value tier of the Kinetis KL1 family.
The MKL16Z64VLH4 is a pin-compatible alternative within the Kinetis KL1 family — same 64-LQFP package, same 48 MHz Cortex-M0+ core, but with 16 KB RAM instead of 8 KB. No PCB change is required for the swap.
The MKL14Z64VLH4 is rated for a 48 MHz core clock — that is the maximum operating frequency for the ARM Cortex-M0+ core on this part.
