NUC1262LE4AE 32-bit microcontroller is based on Arm Cortex-M23 core for Armv8-M architecture with LED Light Strip Interface (LLSI) and USB2.0 full-speed device using built-in 48 MHz oscillator to support the communication with PC/Mobile accessories. It runs up to 72 MHz and features 128 Kbytes of Flash, 20 Kbytes of SRAM, 2.5V ~ 5.5V wide operating voltage, and -40°C ~+105°C operating temperature.

NUC1262LE4AE has 10 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 72 MHz for precision control, up to 9 channels 50 mA high sink current pins that can drive high-brightness LEDs.

NUC1262LE4AE supports USB 2.0 full-speed device interfaces without external crystal oscillators, and USB commands can be used for light control. In addition, the NUC1262 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 NUC1262 series can be widely used in industrial control, lighting control, keyboard/mouse, and home appliances related applications.

NUC1262LE4AE is equipped with plenty of peripherals supporting up to 10 channels of LED Light Strip Interface (LLSI), up to 24 channels of 16-bit PWM, up to 9 channels of 50mA high sink current pins and USB 2.0 full-speed devices without external crystal oscillators. The NUC1262 series also equipped with Timers, Watchdog Timers, up to 10 channels of PDMA, 2 sets of UART, 2 sets of I²C, 2 sets of SPI/ I²S, making it highly suitable for connecting comprehensive external modules. It also integrates high performance analog circuit, such as 8 channels of 12-bit 800 kSPS ADC, and supports high anti-interference capability 7 kV ESD (HBM)/ 4.4 kV EFT.

LQFP48 (7 mm x 7 mm) package is pin-compatible to other Nuvoton series to make the system design and parts change on functional enhancement easily.

Nuvoton NuMaker-NUC1262SE evaluation board 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, Light Control, Key Board/MICE, Home Appliance, etc.
