The NXP MKL17Z128VFT4 is a 32-bit ARM Cortex-M0+ MCU from the Kinetis KL1 series, clocked at 48 MHz with 128 KB Flash and 32 KB RAM. It carries 18 channels of 16-bit ADC and one 12-bit DAC.
128 KB Flash is the mid-density tier in the KL1 family — enough for a modest control loop with a bootloader and a few communication stacks.
Yes, the supply range is 1.71 V to 3.6 V, so 3.3 V logic is within spec. The maximum clock speed is 48 MHz.
Yes, it has one 12-bit DAC in addition to the 18-channel 16-bit ADC.
Yes, it supports I²C, SPI, UART/USART, and LINbus.
The operating temperature range is -40°C to 105°C (industrial grade).
