LC823455 is an audio processing System-on-Chip (SoC) for recording and playback with High-Resolution 32-bit & 192 kHz audio processing capability. It provides required key functions for Portable Sound Solutions which are; Dual CPU configuration, DSP providing intensive processing capability, 4316 KB of internal SRAM that supports the implementation of large-scale programs for WLAN applications, and multiple interfaces to extensively increase its connectivity. It features a broad range of functions including SBC/AAC codec and Active Noise Canceller applicable for wearable audio applications.
Features   Benefits
     
  • ARM® Cortex®-M3 Dual and Proprietary 32 bit DSP (LPDSP) Multi-Core system
 
  • 1-Chip solution lowers BOM cost
  • Internal 4316kB large SRAM for ARM® Cortex®-M3 Dual Core and proprietary 32 bit DSP
 
  • No extra memory required for WLAN application
  • Shorten ambient acoustic sound path
 
  • Enabling ANC function
  • Various proprietary DSP codes for audio processing: MP3 codec, SBC codec, FLAC codec, noise-cancelling, echo cancelling and so forth
 
  • DSP code's development cost reduction. Several DSP codes are available with no additional fee such as noise cancelling, echo cancelling and so forth
  • Hard wired audio functions: - ASRC (Asynchronous Sample Rate Converter) - Hardware mixer - EQ (6 band-Equalizer)
 
  • Power saving by reducing CPU/DSP load
  • Integrated analog functions: - 4 channels of Digital MIC PDM I/F - Low-power Class D HP amplifier - System PLL - dedicated audio PLL, ADC
 
  • Foot-print saving by reducing peripheral BOM count
  • Various interfaces: - USB2.0 HS device - eMMC - SD card - SPI, I2C
 
  • Multiple interfaces increase interface extensibility
  • High resolution 32 bit & 192 kHz audio processing capable
