The NuMicro® NUC029LGE based on the Arm® Cortex®-M0 core operates 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 ~ 5.5V for various operating voltages of external components, 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 NUC029LGE also integrates SPROM (Security Protection ROM) which provides a secure code execution area to protect the intelligent property of developers. NUC029LGE is ideal for industrial control, motor control and metering applications.
The NuMicro® NUC029LGE supports wide voltage range from 2.5V ~ 5.5V and temperature ranging from -40℃ ~ +105℃, up to 256KB of Flash memory, 20KB of SRAM. It also supports high immunity of ESD up to HBM 7KV / EFT 4.4KV. It is also equipped with plenty of peripherals such as USB interface, timers, watchdog timers, RTC, PDMA, EBI, UART, SPI, I²S, I²C, GPIO, up to 10 channels of PWM, up to 9 channels of 12-bit ADC, analog comparator, temperature sensor, LVR (Low Voltage Reset), BOD (Brown-out Detector), 96-bit UID (Unique Identification), and 128-bit UCID (Unique Customer Identification).
