Description

Electronic Component Model: TJ3965-ADJ
Product Category: IC Chips
Manufacturer: Actions Semiconductor Co., Ltd.

Overview
ATJ331X is a third generation single-chip highly integrated digital music system solution for devices dedicating to audio players etc. It includes an audio decoder with embedded RAM and ROM, ADPCM record capabilities and USB interface for downloading music and uploading voice recordings. It also provides an interface to SPDIF, flash memory, LED/LCD, button and switch inputs, headphones, microphone and FM radio input and control. The chip supports WMA and other digital audio standards. For devices like USB-Disk, it can act as a USB mass storage slave device to personal computer system. In addition, its low power consumption leads to long battery life and an efficient and flexible on-chip DC-DC converter allowing many different battery configurations, including 1xAA, 1xAAA and Li-on. The built-in Sigma-Delta D/A includes a headphone driver to directly drive low impedance headphones. The A/D includes inputs for both Microphone and Analog Audio in to support voice recording and FM radio integration features. Thus, it provides a true ’ALL-IN-ONE’ solution that is ideally suited for highly optimized digital audio players.
