Overview
The LC89512W integrates a real-time error correction
circuit and a SCSI interface in a single chip.
Functions
CD-ROM error correction function, subcode readout
function, SCSI interface
Features
Support for double-speed drives at an operating
frequency of 16.9344 MHz
Either SRAM (120 ns), DRAM (80 ns) or pseudo
SRAM (85 ns) can be used.
Support for quad-speed drives at an operating frequency
of 33.8688 MHz
SRAM (70 ns) must be used.
Built-in SCSI interface with built-in 48 mA sink buffer
(Only the TARGET function is supported.)
Built-in 12-byte output FIFO for sub-CPU to host
computer data transmission
Built-in 12-byte input FIFO for host computer to sub-
CPU data transmission
Subcode data can be written to buffer RAM and the sub-
CPU can read the subcode values by connecting the
LC89512 to the CD-DSP subcode pin.
Sub-CPU access of buffer RAM through the LC89512
Built-in function for buffer RAM internal data transfer
Pseudo-SRAM (128-kword
×
8-bit and smaller) can be
used.
DRAM (two 256-kword
×
4-bit chips or two 1-Mword
×
4-bit chips) can be used.
Transfer speeds:
2.8 MB/second (asynchronous mode) (for CD-ROM
decode only operation)
4.2 MB/second (synchronous mode) (CD-ROM decode
operation is not supported in synchronous mode)
Both of these transfer modes use a 16.9344 MHz clock.
(The transfer speed depends on the frequency used.)
Operating frequencies: 16.9344 MHz (up to double
speed), 33.8688 (quad speed)
