This design demonstrates a smart speaker that utilizes wireless functions like Wi-Fi and Bluetooth® to stream music and also respond to voice commands for hands-free operation. The RZ/A1LC is an advanced microprocessor (MPU) design featuring high levels of performance with 2MB of on-chip SRAM and a 400MHz Arm® Cortex®-A9 core to implement any functions required. Additional analog features are wrapped around the MPU, including a Class-D audio solution, the ISL97634 for controlling multiple LEDs with a wide range of PWM dimming control capabilities, and a complete power management solution.

System Benefits
