The NXP MKL15Z64VLK4 is a 32-bit ARM Cortex-M0+ MCU from the Kinetis KL1 series, clocked at 48 MHz with 64 KB Flash and 8 KB RAM. The 1.71 V to 3.6 V supply range and -40 °C to 105 °C operating temperature make it suitable for industrial sensor nodes, motor-control interfaces, and outdoor telecom modules where the board sees extended thermal cycling.
Mixed-signal complement: ADC and DAC
Sixteen 16-bit ADC channels and one 12-bit DAC let this MCU handle analog sensor inputs and output a control voltage without an external converter. The 16-bit resolution on the ADC is useful for precision measurement loops — pressure transducers, load cells, or thermocouple linearization — where 12-bit would leave 1 LSB of quantization error eating into the accuracy budget.
The MKL15Z64VLK4 is classified as Obsolete. No direct pin-compatible successor is listed in the NXP Kinetis KL1 family at this time; buyers looking for a production-continuity path should evaluate the wider Kinetis KL series for a migration option.
