Overview
Ordering number : 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 Note: 1.
For speeds up to 8× speed, use a SCSI master clock frequency of 20 MHz.
Note: 2.
For speeds up to 4× speed, use a SCSI master clock frequency of 16.
9344 MHz.
Functions CD-ROM ECC function, subcode read function, SCSI interface Package Dimensions unit: mm 3214-SQFP144 [LC895124] Features • On-chip SCSI interface (with built-in SCAM selection register) • Supports 8× playback - Using ×16 80-ns DRAMs • Supports 4× playback - Using ×16 80-ns DRAMs or ×8 70-ns DRAMs • Transfer rates: 10 MB/s (synchronous), 5 MB/s (asynchronous) using ×16 80-ns DRAMs*1 • Transfer rates: 8.
467 MB/s (synchronous), 4.
2336 MB/s (asynchronous) using ×8 70-ns DRAMs*2 • PSRAM can be used, providing 5 MB/s transfers in synchronous mode and 5 MB/s transfers in asynchronous mode .
• Supports the connection of up to 32 Mb of buffer RAM (using DRAM) (Up to 2 Mb when PSRAM is used) • The user can freely set the CD main channel, C2 flag, and other areas in buffer RAM.
• Batch transfer function (transfers the CD main channel and C2 flag data in a single operation) • Multi-block transfer function (automatically transfers multiple blocks in a single operation) SANYO: SQFP144 Specifications Absolute Maximum Ratings at VSS = 0 V Parameter Maximum supply voltage I/O voltages Allowable power dissipation Operating temperature Storage temperature Soldering heat resistances (pins only) Symbol VDD max VI, VO Pd max Topr Tstg 10 seconds Ta = 25°C Ta = 25°C Ta ≤ 70°C Conditions Ratings –0.
