GENERAL DESCRIPTION
The Winbond W88111AF/W88112F supports ATAPI CD-ROM specification (SFF 8020). Some
ATAPI operations are executed by hardware to minimize system overhead, including ATAPI
command and packet transfer, data transfer, ATAPI Soft Reset command, and Executive Drive
Diagnostics command. It also features shadow drive support.
The Winbond W88111AF/W88112F supports various types of microprocessors, DRAMs, and DSPs.
The W88111AF/W88112F supports up to 12/20-fold drive speed. It also supports CD-ROM, CD-
ROM/XA, CD-I, Video-CD, Photo-CD , and CD-Plus formats.
The functions of W88111AF/W88112F include CD-ROM data de-scrambling, real-time error
correction of Layer 3 Reed-Solomon Product-like Code (RSPC), error detection, and data transfer to
the host.
The W88111AF/W88112F features real-time ECC correction of one byte per P-word and Q-word. It
can also perform repeated ECC passes to increase the reliability of data.
The W88111AF/W88112F supports up to 1Mbytes of DRAM. It also supports ring-control-register to
add flexibility of external RAM control.
The host interface of W88111AF/W88112F supports data transfer using PIO, single word DMA, and
multi-word DMA modes. There is an 8-byte FIFO to improve the IDE interface throughput.
The W88111AF/W88112F supports multi-block-transfer from external RAM to the host.
* The W88112F supports accelerated error correction/detection to improve system performance.
* The W88112F supports automatic target header search, automatic header comparison, and decoder
interrupt status collection to reduce firmware overhead.
