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. 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.","metaTitle":"NXP MKL03Z16VFG4 Kinetis KL03 ARM Cortex-M0+ MCU, 48 MHz","metaDescription":"NXP MKL03Z16VFG4 Kinetis KL03 MCU: ARM Cortex-M0+ at 48 MHz, 16 KB Flash, 2 KB RAM, 7x12b ADC, 14 I/O, -40°C to 105°C, 16-QFN.
