Smart Speaker
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 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.
Key Features
- Arm® Cortex®-A9 core running at 400MHz with 2MB of on-chip SRAM. Supports DRAM-less solution with low cost. -Low power MCU supports BLE.
- High performance, low input voltage and high PSRR LDO. Highly efficient, synchronous buck delivering up to 2A of continuous output current. PWM boost LED driver allowing up to 7 LEDs.
- High performance Class-D audio amplifiers with digital switching controller.
