ON Semiconductor LC823455 Audio Processing System-on-Chip (SoC) is an ultra-low-power device designed to provide recording and playback, with high-resolution 32-bit and 192kHz audio processing capability. The LC823455 has a Dual CPU configuration and a DSP providing intensive processing capability, 4316KB of internal SRAM that supports the implementation of large-scale programs for WLAN applications, and multiple interfaces for increased extensibility. This SoC features an extensive range of functions including SBC/AAC codec and Active Noise Canceller by the DSP, UART, and ASRC. The highly integrated implementation of this rich set of analog functions results in a miniature footprint with ultra-low power consumption. This, along with its high performance, makes the LC823455 ideal for portable audio systems, wearable IoT, and Smart Home appliances controlled by Voice User Interface (VUI).
