NUC1263 Series


The NuMicro NUC1263 series 32-bit microcontroller is based on Arm Cortex-M23 core for Armv8-M architecture with LED Light Strip Interface (LLSI), I3C, and USB2.0 full-speed device using built-in 48 MHz oscillator to support the communication with PC and Mobile accessories. It runs up to 72 MHz and features 64Kbytes of Flash, 20 Kbytes of SRAM, 2.5V ~ 5.5V wide operating voltage, and -40°C ~+105°C operating temperature.

The NUC1263 series provides two I3C peripheral which can support 1.0V to 3.6V voltage input, compiling with the MIPI I3C v1.0 standard. It can support the fastest transmission rate of 12.5Mbps, support dynamic addressing, simplify multi-sensor management, and reduce system complexity and power consumption. It also supports In-Band interrupt and Hot-Join functions, improving system responsiveness and scalability. I3C combines the simplicity of I²C with the high speed and efficiency of SPI, while providing a low-power and high-performance transmission interface, making it an ideal choice for a variety of applications such as sensors and the Internet of Things (IoT).

The NUC1263 series has 6 channels of LED Light Strip Interface (LLSI) which is easy to control the LED light strip, up to 24 channels of high-speed PWM with clock frequency up to 144 MHz for precision control, up to 9 channels 50 mA high sink current pins that can drive high-brightness LEDs. The NUC1263 series supports USB 2.0 full-speed device interfaces without external crystal oscillators, and USB commands can be used for light control. In addition, the NUC1263 series has a built-in 2 Kbytes of SPROM (Security Protection ROM), which provides an independent security encryption area to protect the intellectual property rights of developers.

The NUC1263 series is also equipped with Timers, Watchdog Timers, up to 10 channels of PDMA, up to 3 sets of UART, up to 3 sets of I²C, up to 3 sets of SPI/ I²S, up to 2 sets of I3C, SPD Hub, making it highly suitable for connecting comprehensive external modules. It also integrates high performance analog circuit, such as up to 16 channels of 12-bit 800 kSPS ADC, up to 4 channels of 8-bit 200 kSPS DAC, up to 4 sets of analog comparators (ACMP), and supports high anti-interference capability 8 kV ESD (HBM)/ 4.4 kV EFT(LQFP64), 4 kV ESD (HBM)/ 4.4 kV EFT(QFN33).

Supported packages include QFN33 (5 mm x 5 mm), QFN48 (7 mm x 7 mm), LQFP48 (7 mm x 7 mm), and LQFP64 (7 mm x 7 mm), which are pin-compatible to other Nuvoton series to make the system design and parts change on functional enhancement easily.

Nuvoton NUC1263 NuMaker evaluation board NuMaker-NUC1263SD and Nu-Link debugger are powerful tools for product evaluation and development. It supports IDEs provided by third parties, such as Keil MDK, IAR EWARM and NuEclipse IDE with GNU GCC compiler.

Target Application: Industrial Control, Industrial Sensor, Light Control, Gaming Light Control, Gaming Keyboard/Mice, DDR5 DIMM, SPD HUB, Graphic Card, Home Appliance, etc.
