LC89515中文资料三洋数据手册PDF规格书

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.)

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
