N Audio Development Kit

Nordic announces the nRF5340 Audio Development Kit, a design platform for rapid development of Bluetooth® LE Audio products. NRF5340 adalah SOC wayarles pertama di dunia dengan dua pemproses ARM® Cortex®-M33, Sesuai untuk audio le dan lain -lain perkara kompleks perkara (IoT) aplikasi.

Kumpulan Minat Khas Bluetooth (Katakan) describes LE Audio as “the future of wireless sound”. This technology is based on the low-complexity communication codec LC3, an enhancement to the low-complexity subband codec (SBC) used by Classic Audio.

Nordic announces the nRF5340 Audio Development Kit, a design platform for rapid development of Bluetooth® LE Audio products. The nRF5340 is the world's first wireless SoC with two Arm® Cortex®-M33 processors, ideal for LE Audio and other complex Internet of Things (IoT) applications. The Bluetooth Special Interest Group (SIG) describes LE Audio as "the future of wireless sound". This technology is based on the low-complexity communication codec LC3, an enhancement to the low-complexity subband codec (SBC) used by Classic Audio.

LC3 ensures that LE Audio has higher audio quality and longer battery life than Classic Audio in all use cases. Extensive listening testing has shown that the LC3 provides better audio quality than SBC at the same sample rate at all sample rates, and delivers equal or better audio quality at half the wireless data rate.

Lower data rates are a key factor in minimizing power consumption in LE Audio products. LE Audio also brings True Wireless Stereo (TWs) and other new features to wireless audio applications, including Audio Sharing.。

The Audio DK’s core nRF5340 SoC combines a high-performance application processor with a fully programmable ultra-low-power network processor for optimal power efficiency and high performance in a dual-core architecture. The 128 MHz Arm Cortex-M33 applications processor contains 1 MB of flash and 512 KB of RAM, making it ideal for handling custom applications and audio codecs such as LC3.

The 64 MHz Arm Cortex-M33 network processor has 256 KB of flash memory and 64 KB of RAM, and is power-optimized to run Nordic Bluetooth LE Audio RF protocol software. The nRF Connect SDK is an nRF5340 SoC development platform that provides nRF5340 Audio DK board level support and supports LE Audio, Bluetooth Low Energy, Thread and other applications.

In addition to the nRF5340 SoC, the Audio DK features Nordic’s nPM1100 power management IC (PMIC) dan pemproses isyarat digital audio CS47L63 Cirrus Logic (DSP).

NPM1100 mempunyai pengawal selia buck boleh dikonfigurasikan yang sangat cekap dan pengecas bateri bersepadu dengan arus pengecasan sehingga 400mA dalam faktor bentuk yang sangat kecil, menjadikannya PMIC yang ideal untuk aplikasi yang terkawal ruang seperti TWS Earbuds. CS47L63 mempunyai DAC berprestasi tinggi dan pemacu output pembezaan yang dioptimumkan untuk sambungan langsung ke beban fon kepala luaran untuk produk earbud dengan mono dan output pembesar suara langsung sahaja.
