Product details

48 MHz Cortex-M0+ in a 3x3 mm QFN

The NXP MKL03Z16VFG4 is a 32-bit ARM Cortex-M0+ MCU from the Kinetis KL03 series, clocked at 48 MHz. It packs 16 KB Flash and 2 KB RAM in a 16-QFN (3x3 mm) exposed-pad package — sized for space-constrained sensor nodes or simple control modules. Fourteen I/O lines bring out I²C, SPI, and UART connectivity; an internal oscillator eliminates the external crystal on low-tolerance links. The 7-channel 12-bit ADC handles analog inputs directly, keeping the BOM count low.

16 KB Flash — firmware budget is tight

16 KB Flash is the hard limit for compiled code. That fits a bootloader, a Modbus RTU slave stack, or a sensor-fusion algorithm.

Frequently asked questions

What is MKL03Z16VFG4's listed speed?

The core processor runs at 48 MHz maximum. That is the ARM Cortex-M0+ clock rate, suitable for sensor polling, UART communication, and simple control loops.
