Product details

48 MHz Cortex-M0+ in a 5×5 mm QFN — what it buys you

The NXP MKL04Z32VFM4 is a Kinetis KL0 series 32-bit ARM Cortex-M0+ MCU running at 48 MHz, with 32 KB Flash and 4 KB RAM. The 14-channel 12-bit ADC samples multiple analog inputs without an external mux.

Package and assembly

Housed in a 32-VFQFN (5×5 mm) with wettable flanks. The 28 I/O are enough for a small keypad, a few LEDs, and a couple of serial buses.

For a BOM freeze, that means you are not scrambling for a replacement mid-production run.

Frequently asked questions

What is the closest pin-compatible alternative to MKL04Z32VFM4?

Within the Kinetis KL0 family, the MKL04Z64VFM4 (64 KB Flash) shares the same 32-HVQFN footprint and pinout. Firmware needs a rebuild for the larger Flash map, but the board layout stays identical.

What is MKL04Z32VFM4's listed speed?

The core runs at 48 MHz, which is the maximum clock for the Kinetis KL0 series Cortex-M0+.

What compliance documentation does NXP provide for MKL04Z32VFM4?

NXP provides RoHS and REACH compliance declarations for this part. The wettable-flank package is also halogen-free per typical NXP material declarations. Contact us for the specific certificates.
