ATJ2063 PRODUCT DATASHEET
1 .Introduction
ATJ2063 is a third generation 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 and ROM, USB
interface for downloading music and uploading voice recordings. ATJ2063 also provides
an interface flash memory, LED/LCD, button and switch inputs, headphones. ATJ2063
contains a high performance DSP, which can easily be programmed to support many
kinds of digital audio standards such as WMA, etc. For devices like USB-Disk, ATJ2063
can act as a USB mass storage slave device to personal computer system. ATJ2063 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 and 1xAAA.
The built-in Sigma-Delta DAC includes a headphone driver to directly drive low impedance
headphones. ATJ2063 provides a true “ALL-IN-ONE” solution that is ideally suited for
highly optimized digital audio players.
Features:
z MPEG1/2/2.5 Audio Layer 1,2,3 decoder, bit rate 8-448Kbps, 8-48KHz, CBR/VBR
z Support WMA Decoder, bit rate 32-384Kbps, 8-48KHz
z 24 bits DSP Core with on-chip Debug Support Unit (DSU)
z On-chip DSP PM with SRAM(16K*24) ,can be switched to be MCU memory space
z On-chip DSP DM with SRAM(16K*24), can be switched to be MCU memory space
z Integrated MCU with DSU, the instruction set is compatible with Z80
