LC89515 Overview
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 patible. Thus this product can replace the LC8951 without change.
LC89515 Key Features
- Software and pin patibility with the LC8951 (Changes were made to internal registers, the SRAM interface, and other aspe
- 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 mand FIFO (for easy SCSI support)
- Built-in 12-byte status FIFO
- CMOS circuits, single 5 V power supply
