It carries USB OTG on-chip plus I²C, SPI, UART, and LINbus. ## 36-WLCSP — rework reality The 36-WLCSP (2.37 × 2.46 mm) is a wafer-level chip-scale package with no leads — the solder balls are directly on the die. That means NXP is still manufacturing it, and there is no last-time-buy or end-of-life notice on the horizon.","metaTitle":"NXP MKL26Z128CAL4R Kinetis KL2 MCU, 48 MHz, 128 KB Flash, 36-WLCSP","metaDescription":"NXP MKL26Z128CAL4R 32-bit ARM Cortex-M0+ MCU, 48 MHz, 128 KB Flash, 16 KB RAM, USB OTG, 12-bit ADC/DAC, 36-WLCSP, -40 to 85°C.
