Systemchips til avanceret audioprocessering
ON Semiconductor har frigivet den seneste audioprocesserings-systemchip til brug i mobile devices (in english).
ON Semiconductor has released its latest high-resolution audio processing System-on-Chip with 1656KB SRAM and power-efficient hardware acceleration, bringing extra space savings and longer battery life to devices such as smartphones, wearable accessories and voice recorders.Powering the LC823450 are a highly efficient ARM Cortex-M3 core and ON Semiconductor’s 32-bit/192kHz audio-processing engine with hardware-based MP3 encoding/decoding and wireless-audio support, which boosts performance and power efficiency.
In addition, a large selection of royalty- and license-free DSP code samples are available, which help accelerate software design and minimise development costs. These include advanced functions such as noise canceller, and S-Live (Low-frequency Intelligence Virtual Excitation) for enhanced playback of low frequencies.
With its generous on-chip SRAM, the new LC823450 has plentiful memory for audio processing and application tasks without needing a companion memory chip. Designers can also take advantage of rich integrated audio peripherals, such as an analogue/digital converter, phase-locked loop and class-D amplifier. In addition, industry-standard interfaces such as SPI, I2C, SDCard and UART enable product designers to build in versatile connectivity.
- High-resolution audio takes listening pleasure to a new level, and our new LC823450 delivers superior experiences on mobile devices through class-leading integration and power efficiency, says Atsushi Bando, General Manager of the ON Semiconductor, System Solutions Group.
- Rich integrated features, hardware acceleration and easy software terms also make life easier for product developers by helping manage development costs and minimise time to market.
The Pb-free LC823450 is packaged in a compact 5.52 mm x 5.33 mm WLP-154 that reduces footprint by up to 85% over competing solutions. The device is also available in a TQFP-128L package.
