SANYO LC895994 Datasheet

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 data (during decoding and encoding)

• ATIP decoding and CRC checking for both encoding and decoding

• CLV servo control using ATIP data during encoding

• CIRC code insertion and EFM modulation during encoding

• Support for PCA random EFM output during encoding

• Support for CD-ReWritable (CD-RW) Write Strategy signal output

• Access to buffer RAM from microcontroller via LC895994

• Built-in ATAPI (IDE) interface

• Speeds of 12× for decoding and 4× for encoding — Frequencies

Decoding: 17.2872 MHz Encoding: 17.2872 MHz without Write Strategy

support

69.1488 MHz with Write Strategy support

• IDE Transfer rate: 13.3 MB/s when using 16-bit data path 80-ns DRAM chips

• Buffer RAM sizes between 1 and 32 megabits (using 16bit DRAMs)

• User control over sizes of CD main channel, C2 flag areas in buffer RAM

• Built-in batch transfer function for transferring entire CD main channel, C2 flag, or subcode area in a single operation

• Built-in multiblock transfer function for transferring multiple blocks in a single operation
