Ordering number : EN5829A 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. • Built-in multiblock transfer function for transferring multiple blocks in a single operation. • Automatic sequencing of encoding and decoding processing for a reduced processing load on the system microcontroller. Package Dimensions Features unit: mm • ECC and EDC correction/addition for CD-ROM data (during decoding and encoding) • Subcode decoding/encoding complete with error detection and error correction • 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 • Access to buffer RAM from microcontroller via LC895926 • Built-in SCSI interface • Speeds of 24× for decoding and 12× for encoding • Transfers speeds of 10 megabytes/s (synchronous) and 5 megabytes/s (asynchronous) with 16-bit 50-ns EDODRAMs • Buffer RAM sizes between 1 and 32 megabits (using 16bit EDO-DRAMs) • User control over sizes of CD main channel, C2 flag, and subcode areas in buffer RAM • Built-in batch transfer function for transferring entire CD main channel, C2 flag, or subcode area in a single operation. 3153A-QFP160E [LC895926] SANYO: QIP160E SANYO Electric Co.,Ltd.
