SANYO LC895196K Datasheet
Overview
The LC895196K is a large scale integrated circuit
equipped with CD-ROM functions and an internal ATAPI (IDE) interface.
Functions
• CD-ROM ECC functions, SUB-CODE read function,
ATA-PI (IDE) interface (Registers, etc.).
Features
• Built-in ATA-PI (IDE) interface.
•32× speed supported
Uses the EDO-DRAM (× 16, 50 ns)
16.6 Mbyte/s (with IORDY)
Operating frequency: 33.8688 MHz
•24×speed supported
Uses the EDO-DRAM (× 16, 60 ns)
16.6 Mbyte/s (without IORDY)
Operating frequency: 33.8688 MHz
• Supports between 1 Mbit and 4 Mbit of buffer RAM
when DRAM is used
• The user can flexibly set the CD main channel, the C2
flags, and the subcode regions in the buffer RAM
• Built-in batch transfer function. (Where the batch
transfer function is a function that transmit the CD main
channel, C2 flags, subcodes, etc. all at once.)
• Built-in multitransmit function. (Where the
multitransmit function is a function that automatically
transmits multiple blocks at once.)
• Built-in intelligent functions (auto buffering, auto
decoding, CD-R compatibility)
• Built in subcode P-W buffering function (NO-ECC) and
CD-TEXT compatibility
