48 MHz Cortex-M0+ — what it means for throughput
Memory budget for firmware and data
32 KB Flash and 4 KB RAM set the firmware boundary. A Modbus RTU slave reading four analog inputs and driving two relays fits comfortably.

Product details
Frequently asked questions
What is the package type of MKL02Z32VFK4?
The MKL02Z32VFK4 is supplied in a 24-VFQFN exposed-pad package (24-QFN, 4x4 mm body).
Can MKL02Z32VFK4 be used as a replacement for MKL02Z32VFG4?
The MKL02Z32VFK4 and MKL02Z32VFG4 share the same base part number and core specs (48 MHz, 32 KB Flash, 4 KB RAM, same peripherals), but the VFK4 suffix denotes a 24-QFN package while the VFG4 suffix indicates a different package variant. Verify pin compatibility and footprint before substituting.
What is the datasheet for MKL02Z32VFK4?
The full datasheet is published by NXP under the base product number MKL02Z32; it covers the entire KL02 series including the MKL02Z32VFK4 variant.
