Product details

The NXP MKL05Z32VFK4 is a 32-bit ARM Cortex-M0+ microcontroller from the Kinetis KL0 series, running at 48 MHz with 32 KB Flash and 4 KB RAM. It has 22 I/O, I2C/SPI/UART, a 12-bit ADC (12-channel) and a 12-bit DAC in a 24-VFQFN package measuring 4×4 mm.

Memory and peripheral fit for sensor-interface and control loops

Lifecycle — still active, no LTB pressure

No last-time-buy notice has been issued. For a BOM freeze or a multi-year production program, this part is not under phase-out pressure — the Kinetis KL0 family remains a current portfolio entry.
