The NXP MKL17Z64VFM4 is a 32-bit ARM Cortex-M0+ microcontroller from the Kinetis KL1 series, clocked at 48 MHz with 64 KB Flash and 16 KB RAM. It integrates a 11-channel 16-bit ADC, DMA controller, I²S, PWM, and a watchdog timer, with connectivity covering I²C, FlexIO, SPI, and UART/USART. The 32-UFQFN Exposed Pad package (5x5 mm) and 1.71 V to 3.6 V supply range make it a fit for space-constrained, battery-operated or industrial sensor nodes where the -40°C to 105°C temperature grade is required.
At 48 MHz, the Cortex-M0+ core handles real-time control loops and basic protocol parsing. The 16 KB RAM limits buffer-heavy operations.
Temperature range and qualification reality
It is not AEC-Q100 listed — the industrial temperature range covers the operating condition but no PPAP or zero-defect production flow is confirmed. For automotive-grade requirements, a Kinetis KL1x with Q suffix (e.g., MKL17Z64VFM4 with AEC-Q grade) would be the qualified path.
