【Audio Codecs: The Cornerstone of High Fidelity and Ultra-Low Power Consumption】
The audio codec serves as the heart of the evaluation board, responsible for high-quality conversion between analogue and digital signals. Renesas' audio codec product line is renowned for its exceptional energy efficiency ratio, specifically optimised for portable and always-on devices. Its core advantages include:
Ultra-low power consumption: For instance, the DA7212 audio codec, designed for portable devices, consumes as little as 650 microwatts (µW) in its ‘always-on mode’. This enables devices like headphones and smartwatches to achieve days or even weeks of battery life while continuously monitoring voice wake-up words.
Professional-grade audio processing: Integrated audio enhancement features including a 5-band equaliser (EQ), automatic level control (ALC), and noise gate eliminate the need for complex external circuitry, enabling developers to achieve professional-grade sound tuning.
High Integration and Flexibility: Supports I²C control interfaces and multiple digital audio formats, enabling seamless integration as an audio expansion board for main microcontrollers (MCUs) via the standard mikroBUS™ interface.
【USB Audio: Plug-and-Play High-Fidelity Transmission】
USB audio represents a mature standard for high-quality digital audio transmission. Across multiple Renesas evaluation platforms, the USB interface serves as the key channel for audio data streaming and device control.
On the RZ/Five evaluation board, the USB interface not only handles power supply and program debugging, but its USB Host functionality also enables connection to external USB sound cards or microphone arrays, facilitating rapid construction of USB audio input/output systems.
The RA4E1 Voice Reference Kit operates as an audio device via its USB Full Speed port, allowing direct recognition by computers as a high-quality audio input/output device. This simplifies development for voice recognition or audio conferencing applications.
【Wireless Audio: Breaking Free from Wires for Unrestricted Experience】
Wireless audio represents a mainstream trend in consumer electronics, presenting challenges in ensuring low latency, high fidelity, and extended battery life within complex wireless environments. Renesas offers comprehensive wireless audio module and integrated circuit (IC) solutions.
Low Latency, High Fidelity: Renesas' wireless audio platform supports sampling rates up to 48kHz, delivering fixed-low-latency transmission to ensure synchronised audio-visual output for gaming, film viewing, and real-time calls.
Robust Interference Resistance: Operating in globally licence-free 1.9GHz and 2.4GHz bands, combined with advanced RF CMOS technology and anti-interference algorithms, ensures stable connectivity even in dense Wi-Fi and Bluetooth environments.
Flexible Topology: Supports point-to-point, point-to-multipoint (e.g., one transmitter to multiple headphones) and multipoint-to-multipoint audio data streams, suitable for complex scenarios such as wireless surround sound systems and multi-conference room microphone setups.
