The Smart Phone Docking System supports Apple iPhone and most kinds of Android smart phones. User can play music or video files through the docking system, which has been widely used in individuals and home entertainment applications. The Smart Phone Docking System must include a high-performance microcontroller to provide USB interface, LCD display data transfer, power management, phone battery charging, remote control signal receiving, and audio DSP module control. Due to the need for high computing power MCU with USB 2.0 interface, the NUC123 series MCU is suitable for Smart Phone Docking System applications.

The NUC123 series provides high performance and low-cost 32-bit Arm® Cortex®-M0 core with USB full speed 2.0 interface, runs up to 72 MHz, and supports 32-bit hardware multiplier, wide operating voltage range 2.5V to 5.5V, Flash ROM up to 68 KB and RAM up to 20 KB, highly integrated 10-bit ADC, 150 kSPS conversion rate, internal RC 22MHz OSC, USB 2.0 full-speed device interface, and rich peripheral such as I²Cx2 ,SPIx3, UARTx2, input I/O 5V tolerance, Anti-theft lock code bit, 96-bit Unique ID and 128-bit Unique customer ID, and strong anti-jamming ability (ESD 8kV, EFT 4kV).
