Cirrus Logic CS48L32-CWZR

오디오 프로세서Quad-SPI, SPI100MHz768kB-40°C ~ 85°C

Overview

The CS48L32-CWZR combines power optimized mic inputs with a programmable HaloCore™ to provide a platform for low power input voice processing; ideal for IOT devices, wearable and mobile applications where maximizing the battery life is essential.The CS48L32-CWZR features a 24-bit audio processor with 104 dB signal-to-noise ratio (SNR) mic input (16 kHz) and supports up to four analog or four digital microphone (DMIC) inputs. Low power input modes are available for “always on voice” (i.e., voice trigger) functionality using either analog or digital input. Two additional digital audio serial ports can support a wide range of audio sample rates and serial interface formats. This IC can be powered from 1.8 and 1.2 volt supplies and its power, clocking and output driver architectures are designed to maximize battery life when in voice, music and standby modes.The Halo Core DSP supports multiple concurrent audio features, including voice-trigger detection, noise reduction, media enhancement, plus more. Support for third-party DSP programming provides far-reaching opportunities for product differentiation.
