Wcd9341 Datasheet ✨
The datasheet for the WCD9341 reveals a highly integrated architecture designed to save space and reduce power consumption in tight mobile form factors.
: Powers ultra-low-power voice processing and supports simultaneous wake-word detection for voice assistants.
: Includes a dedicated hardware block for Active Noise Cancellation (ANC) and supports "always-listening" voice UI wake-up words at low power. Application Guide SM-G960U/W/U1 Common - iFixit wcd9341 datasheet
The chip is particularly well‑suited for any system requiring , immersive audio playback , or professional‑grade recording .
The datasheet separates the WCD9341 into several critical internal subsystems: Audio Processing Subsystem The datasheet for the WCD9341 reveals a highly
Integrated feedforward and feedback hybrid ANC processing loops.
Balanced or single-ended configurations for routing audio to external power amplifiers. 3. Pinout and Interface Configuration Application Guide SM-G960U/W/U1 Common - iFixit The chip
is designed for high-resolution audio playback and low-power "always-on" voice processing. : Supports up to 384-kHz/32-bit PCM audio.
The datasheet notes that the WCD9341 is . It requires initialization via I2C (address 0x1B or 0x1C). The boot sequence (per the datasheet flowchart) is:
