LC895195
ATA-PI (IDE) CD-ROM Decoder LSI
Preliminary
Overview
The LC895195 is a CD-ROM decoder LSI that includes
both an on-chip IDE interface that was developed jointly
with Western Digital and an on-chip subcode ECC
function.
Features
• ATA-PI (IDE) interface
• Supports 16× playback (with IORDY) - Using ×16 70 ns
DRAMs
• 16.6 MB/s transfer rate: Using ×16 70 ns DRAMs
• 8.33 MB/s transfer rate: Using ×8 70 ns DRAMs
• Supports the use of from 1 M to 32 M of buffer RAM.
(DRAM)
• Allows the user to arbitrarily set the CD main channel,
C2 flag and subcode areas in buffer RAM.
• Batch transfer function (function for transferring the CD
main channel, C2 flag and subcode data in one
operation)
• Multi-transfer function (function for sending multiple
blocks in one operation)

Note: 1. NC (no connection) pins must be left open.
2. Pin names (signal names) that begin with a Z have negative (inverted) logic.
3. VSS0 is the logic system ground and VSS1 is the IDE interface driver ground.
