Description  
The Atmel AT78C1501 is a high-performance DVD/CD ATAPI Ultra DMA66 Interface  
Controller, designed to interface to the AT78C1502 DVD Servo Controller, the  
AT78C1503 DVD Read Channel and the AT78C1504 Automatic Laser Power Control  
(ALPC). The interface controller (AT78C1501) contains ARM® and AVR® microcontrol-  
lers, buffer management, error correction code (ECC) and encoder/decoder (ENDEC)  
for DVD and CD. Also included are a writeable control store for timing generation and  
an on-board frequency synthesizer to generate system frequencies from one crystal.  
ATA66/ATAPI66 and I2S interfaces are provided.  
The major functions of the AT78C1501 include data format encoding/decoding, error  
detection/correction, buffer management, ATAPI host interface and serial interface  
master. The AT78C1501 also includes an embedded ARM7 RISC Core to perform all  
system (drive) microprocessor functions and an embedded AVR RISC core to perform  
internal data path and buffer management control.  
The AT78C1501 disk formats include DVD-ROM, DVD-RAM (Read/Write), CD-ROM,  
CD-R (Read/Write), CD-RW (Read/Write), DVD-R (Read/Write), DVD-RW  
(Read/Write), and DVD+RW (Read/Write).
