LC895124 Description
EN 5240 CMOS LSI LC895124 CD-ROM Driver with On-Chip SCSI Interface and Subcode Functions Preliminary Overview The LC895124 is the next-generation version of the LC89512 and is a CD-ROM decoder that includes a SCSI interface that supports the high-speed transfers (10 MB/s) of the FAST SCSI standard. High-speed transfer mode supports a 10-MB/s (synchronous) transfer rate using ×8 80-ns DRAMs Subcode ECC function...
