GENERAL DESCRIPTION
The NuMicro® NUC100 series 32-bit microcontroller (MCU) is embedded with the ARM® Cortex® M0 core with the cost equivalent to traditional 8-bit MCU. The NUC100 series is also provided with plenty of peripheral devices, such as Timers, Watchdog Timer, Window Watchdog Timer, RTC, PDMA with CRC calculation unit, UART, SPI, I2C, I2S, PWM Timer, GPIO, PS/2, EBI, Smart Card Host, 12-bit ADC, Analog Comparator, Low Voltage Reset Controller and Brown-out Detector. Additionally, the NUC120 USB Line is equipped with a USB 2.0 Full-speed Device. These peripherals have been incorporated into the NUC100 series to reduce component count, board space and system cost. The NUC100 series is equipped with ISP (In-System Programming), IAP (In-ApplicationProgramming) and ICP (In-Circuit Programming) functions, which allows the user to update the program under software control through the on-chip connectivity interface, such as SWD, UART and USB.
