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 minimize 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 analog/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.

The Pb-free LC823450 is packaged in a compact 5.52 mm x 5.33 mm WLP-154 and is priced at $8.34 per unit in 1,000 unit quantities. The device is also available in a TQFP-128L, priced at $8.00 per unit in 450 unit quantities.
