CMOS IC
LC895926
CD-R Encoder/Decoder IC with Built-in SCSI Interface
Overview
The LC895926 is a CD-R IC that provides a wide range of
functions including CD-ROM decoding (including ECC)
and encoding, subcode encoding and decoding, CD
encoding, ATIP decoding and CLV servo, and a SCSI
interface that includes the register block.
鈥?Built-in multiblock transfer function for transferring
multiple blocks in a single operation.
鈥?Automatic sequencing of encoding and decoding
processing for a reduced processing load on the system
microcontroller.
