NUC126VG4AE Datasheet | Nuvoton Technology

DESCRIPTION The Nu Micro® 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 1.8 V to 5.5 V for various operating voltages of external ponents, 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 2.5 V to 5.5 V and temperature ranging from -40°C to 105°C, up to 256 KB of Flash memory, 20 KB of SRAM, 4 KB 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 8 k V ESD (HBM)/4 k V 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 parator, temperature sensor, low voltage reset, brown-out detector, 96-bit UID (Unique Identification), and 128-bit UCID (Unique Customer Identification). 1.1 Key Feature and Application Product Line USB USCI UART NUC126 2.0 FS Device I2C SPI/I2S ISO PWM 7816 PDMA ADC ACMP RTC VBAT VDDIO Y Table 1.1-1 Key Features Support Table The Nu Micro® NUC126 series is suitable for a wide range of applications such as: - Industrial Automation - PLCs - Inverters - Home Automation - Security...
