lc895994

Manufacturer Part Number
lc895994
Description
Cd-r Encoder/decoder Lsi With Built-in Atapi Ide
Manufacturer
Sanyo Semiconductor Corporation
Datasheet
Ordering number : EN*5824
Preliminary
Overview
The LC895994 is a CD-R LSI that provides a wide range
of functions including CD-ROM decoding (including
ECC) and encoding, subcode Q encoding (CRC addition)
and decoding, CD encoding, ATIP decoding and CLV
servo, and an IDE interface that includes the register
block.
Features
• ECC and EDC correction/addition for the CD-ROM
• ATIP decoding and CRC checking for both encoding
• CLV servo control using ATIP data during encoding
• CIRC code insertion and EFM modulation during
• Support for PCA random EFM output during encoding
• Support for CD-ReWritable (CD-RW) Write Strategy
• Access to buffer RAM from microcontroller via
• Built-in ATAPI (IDE) interface
• Speeds of 12 for decoding and 4 for encoding
• IDE Transfer rate: 13.3 MB/s when using 16-bit data
• Buffer RAM sizes between 1 and 32 megabits (using 16-
• User control over sizes of CD main channel, C2 flag
• Built-in batch transfer function for transferring entire
• Built-in multiblock transfer function for transferring
data (during decoding and encoding)
