Overview: Ordering number : EN4272C CMOS LSI LC89515K
CD-ROM/CD-I Error Correction/ Host Interface LSI Overview
The LC89515K is a version of the LC8951 in which certain aspects of the internal registers have been improved to make them even easier to use in CD-ROM and CD-I products. The basic blocks are identical to those in the LC8951 and these products are software and pin compatible. Thus this product can replace the LC8951 without change. (However, this product is provided in a slightly different package: a short lead type QIP-80E as opposed to the QIP-80A.) The LC89515K is an error correction and host interface LSI for use in CD-ROM and CD-I products. This product integrate in a single chip all CD-ROM specific functions, including the error correction that was previously implemented in software on a microprocessor and the CD player and host computer interfaces that were previously implemented in discrete components or gate arrays. The use of the LSI can provide significant improvements in CD-ROM and CD-I players, including increased transfer rates, miniaturization, increased reliability, an improved cost performance ratio, and a more efficient development period.
