The NXP MK20DN128VLF5 is an ARM Cortex-M4 microcontroller running at 50 MHz, with 128 KB of Flash and 16 KB of RAM. It is a single-core 32-bit part in a 48-LQFP package, surface-mount, with 29 GPIOs.
The MK20DN128VLF5 is RoHS-compliant by design (NXP's standard lead-free finish). For REACH or conflict-minerals declarations, NXP provides compliance documentation on request — the part's base number MK20DN128 is registered in their material disclosure system.
The Kinetis K20 family includes pin-compatible density upgrades in the same 48-LQFP package, such as the MK20DN256VLF5 with 256 KB Flash and 32 KB RAM. No board respin is needed to swap between them.
The MK20DN128VLF5 is rated at 50 MHz core speed. That's the maximum CPU clock for the ARM Cortex-M4 core on this part.
NXP provides RoHS compliance documentation for the MK20DN128VLF5 as standard. REACH and conflict-minerals declarations are available through NXP's material disclosure system for the base part number MK20DN128.
