1 Short Descriptions
Data Sheet
The ATJ2075 is a single-chip highly-integrated digital music system solution for devices such as dedicated
audio players, PDAs, and cell phones. It includes an audio decoder with a high performance DSP with
embedded RAM, ADPCM/AG record capabilities and USB interface for downloading music and uploading
voice recordings. ATJ2075 also provides an interface to S/PDIF audio data input, flash memory, LED/LCD,
button and switch inputs, headphone, and microphone, and FM radio control. The ATJ2075’s programmable
architecture supports the MP3 and WMA and other digital audio standards. For devices like USB Flash Disk,
the ATJ2075 can act as a USB mass storage slave device to personal computer system. The ATJ2075 has low
power consumption to allow long battery life and an efficient flexible on-chip DC-DC converter that allows
many different battery configurations, including 1xAA, 1xAAA, 2xAA,2xAAA.
