Internal oscillator saves a crystal for non-critical timing. ## Peripherals and connectivity — what's on the bus This part packs USB OTG (host and device), I²C, SPI, UART/USART, and LINbus — enough for a USB-to-serial bridge, a small HMI with a touch controller, or a CAN gateway if you add an external CAN transceiver. The 16-bit ADC and 12-bit DAC cover analog sensor inputs and simple analog output loops. The 50 GPIOs in the 64-LQFP package give you room for a parallel LCD interface or a keypad matrix without multiplexing. ## Lifecycle and sourcing — active, no LTB pressure","metaTitle":"NXP MKL46Z128VLH4 Kinetis KL4 MCU, 48 MHz, 128 KB Flash, 64-LQFP","metaDescription":"NXP MKL46Z128VLH4 32-bit ARM Cortex-M0+ MCU, 48 MHz, 128 KB Flash, 16 KB RAM, USB OTG, -40 to 105°C.
