Short Descriptions
The ATJ2073 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. ATJ2073 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 ATJ2073’s programmable
architecture supports the MP3 and other digital audio standards. For devices like USB Flash Disk, the ATJ2073
can act as a USB mass storage slave device to personal computer system. The ATJ2073 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.
