Ultra low power Audio Decoder LSI
CXD5091AGG
Description
The CXD5091AGG is an audio decoder LSI that achieves super-low power consumption and supports many
codecs. Useful interface such as NAND/NOR flash memory and Memory Stick is supported, and it comprises
analog circuits such as audio D/A converter and SAR A/D converter. The CXD5091AGG is suitable for portable
audio players and cellular phone audio backend.
