NUC125LC2AE
The NUC125LC2AE is a 32-bit microcontroller ( MCU ) with ARM® Cortex®-M0 core. It runs up to 50 MHz and supports 32 KB Flash, 8 KB SRAM , 12-bit ADC , 48 MHz high speed RC oscillator supporting crystal-less USB transfer and 23-ch PWM /B PWM which makes it powerful in USB communication and data control-processing. The NUC125LC2AE supports industrial operating temperature from - 40 ℃ to 105 ℃ , wide range power supply from 2.5V to 5.5V , and high noise immunity ( 8 kV ESD, 4 kV EFT ) . The available package is LQFP48.
The NUC125LC2AE supports independent VDDIO pin and voltage adjustable interface ( VAI ) with individual I/O ( 1.8V - 5.5V ) connecting to the external components with different voltage ranges to allow more flexibility in designs.
The NUC125LC2AE also embedded an extra SPROM ( Security Protection ROM ) , providing a secure code execution area to protect the intelligent property of developers.
Target Application:USB Composite Device, Gaming Mouse/Keyboard/Pad, USB Type-C Earphone, Industrial Automation, IoT device, etc.
