The part lives in a 20-ball WLCSP (1.99×1.94 mm) — that footprint is the whole story: you pick this MCU when board real estate is the tightest constraint and a few millimetres decide the layout. Connectivity covers I2C, SPI, and UART/USART, enough for a local sensor bus or a serial link to a host controller. ## Package reality — WLCSP handling The 20-WLCSP (1.99×1.94 mm) is a wafer-level chip-scale package with no mould compound. PCB pads must match the ball layout exactly; rework is not trivial.","metaTitle":"NXP MKL02Z32CAF4R Kinetis KL02 MCU, 48MHz ARM Cortex-M0+, 32KB Flash, 20-WLCSP","metaDescription":"NXP MKL02Z32CAF4R Kinetis KL02 32-bit MCU: 48MHz ARM Cortex-M0+, 32KB Flash, 4KB RAM, 18 I/O, 1.71-3.6V, -40 to 85°C, 20-WLCSP.
