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.

Features

• Software and pin compatibility with the LC8951

(Changes were made to internal registers, the SRAM

interface, and other aspects.)

• Support for CD-ROM (mode 1) and CD-I (mode 2,

forms 1 and 2)

• All CD-ROM/CD-I special functions implemented on a

single chip

• Hardware error detection and correction for high speed,

without relying on software

• Real-time error correction: Error correction and

detection are possible without interrupting the host

interface bus.

• Fast transfers: up to 2.3 MB/s (18.4 Mb/s)

• Support for low-speed hosts (multiple block buffering)

• Built-in host interface command FIFO (for easy SCSI

support)

• Built-in 12-byte status FIFO

• CMOS circuits, single 5 V power supply
