Ordering number : EN*5241

22896HA (OT) No. 5241-1/11

Functions

CD-ROM ECC function, subcode read function, SCSI

interface

Features

• On-chip SCSI interface (with built-in SCAM selection

register)

• Supports 8

× playback - Using ×16 80-ns DRAMs

• Supports 4

× playback - Using ×16 80-ns DRAMs or ×8

70-ns DRAMs

• Transfer rates: 10 MB/s (synchronous), 5 MB/s

(asynchronous) using

• Transfer rates: 8.467 MB/s (synchronous), 4.2336 MB/s

(asynchronous) using

• Supports the connection of up to 32 Mb of buffer RAM

(using DRAM)

• The user can freely set the CD main channel, C2 flag,

and other areas in buffer RAM.

• Batch transfer function (transfers the CD main channel

and C2 flag data in a single operation)

• Multi-block transfer function (automatically transfers

multiple blocks in a single operation)

• High-speed transfer mode supports a 10-MB/s

(synchronous) transfer rate using

×8 80-ns DRAMs

• Subcode ECC function

Note: 1. For speeds up to 8

× speed, use a SCSI master

clock frequency of 20 MHz.

× speed, use a SCSI master

clock frequency of 16.9344 MHz.
