What should engineers review before using VS1063A-L?

Review the required encoder or decoder format, clock setting, separate AVDD/CVDD/IOVDD supply requirements, analog reference selection and GBUF headphone connection. GBUF must not be connected to ground.

What is the pinout of VS1063A-L?

Use the VS1063A-L datasheet for the official pinout diagram and pin names. In PartGenie, ask Datasheet AI about VS1063A-L pinout to locate pins, power rails, and interface signals before layout.

AI summary

VS1063A-L is a multifunction audio codec for embedded playback, recording and streaming designs requiring on-chip stereo ADC/DAC and compressed-audio processing.

Best for

Embedded audio players with compressed-audio playback
Microcontroller-controlled audio recording
Streaming and full-duplex voice codec designs

Avoid if

A simple low-power analog-only audio solution is required
The design cannot support separate analog, core and I/O power domains
Mechanical package data cannot be verified before PCB layout

Check before use

Confirm the exact VS1063A variant because VS1163A lacks MP3 encoding and VS8063A lacks MP2/MP3 functions.
Use the recommended VS1063a patches package for recording applications.
Verify codec licensing obligations for AAC and WMA use.
