1 GENERAL DESCRIPTION
The NuMicro® NUC126 series microcontroller based on the ARM® Cortex® -M0 core operates at
up to 72 MHz. With its crystal-less USB 2.0 FS interface, it is able to generate precise frequency
required by USB protocol without the need of external crystal. It features adjustable VDDIO pins for
specific I/O pins with a wide range of voltage from 1.8V to 5.5V for various operating voltages of
external components, a unique high-speed PWM with clock frequency up to 144 MHz for
precision control, and an integrated hardware divider to speed up the calculation for the control
algorithms. Apart from that, the NUC126 also integrates SPROM (Security Protection ROM)
which provides a secure code execution area to protect the intelligent property of developers. The
NUC126 series is ideal for industrial control, motor control and metering applications.
The NUC126 series supports the wide voltage range from 2.5V to 5.5V and temperature ranging
from -40to 105, up to 256 Kbytes of Flash memory, 20 Kbytes of SRAM, 4 Kbytes of ISP (In-
System Programming) ROM as well as ICP (In-Circuit Programming) ROM and IAP (In-
Application Programming) ROM in 48-, 64- or 100-pin packages. It also supports high immunity of
8KV ESD (HBM)/4KV EFT. It is also equipped with plenty of peripherals such as USB interface,
Timers, Watchdog Timers, RTC, PDMA, EBI, UART, Smart Card Interface, SPI, I²S, I²C, GPIO,
up to 12 channels of 16-bit PWM, up to 20 channels of 12-bit ADC, analog comparator,
temperature sensor, low voltage reset, brown-out detector, 96-bit UID (Unique Identification), and
128-bit UCID (Unique Customer Identification).
