It has 28 I/O lines, I²C, SPI, UART, and LINbus connectivity, plus a 9-channel 12-bit ADC. The 32-HVQFN package with wettable flanks means the solder joints are AOI-inspectable — a practical advantage for production lines that need to verify solder quality on QFN packages without X-ray. At 48 MHz the Cortex-M0+ single-cycle I/O and 32-bit data path keep interrupt latency low for real-time control loops. The 4 KB RAM is sufficient for a bare-metal state machine or a lightweight scheduler.","metaTitle":"NXP MKL14Z32VFM4R Kinetis KL1 MCU, ARM Cortex-M0+, 48 MHz","metaDescription":"NXP MKL14Z32VFM4R Kinetis KL1 ARM Cortex-M0+ MCU, 48 MHz, 32 KB Flash, 4 KB RAM, 28 I/O, -40 to 105°C, 32-HVQFN wettable flank.
