NUC121ZC2AE


The NUC121ZC2AE 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 17-ch PWM /B PWM which makes it powerful in USB communication and data control-processing. The NUC121ZC2AE 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 QFN33.

The NUC121ZC2AE 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.
