Overview
The LC89517K is a CD-ROM/CD-I error correction LSI
that integrates the functions provided by the improved
version of the LC89515 and a sub-code function in a
single chip. The improved version of the LC89515
additionally supports double speed operation.
Features
Support for double speed operation (selectable by setting
an internal register) at an operating frequency of
16.9344 MHz
Built-in 12-byte FIFO for transfers from the system
microcontroller to the host computer
Built-in 12-byte FIFO for transfers from the host
computer to the system microcontroller
Direct connection to the LC8955 (an ADPCM decoder
LSI) and the LC8953 (a 68000 CPU peripheral interface
LSI)
Sub-code data can be written to buffer RAM simply by
connecting the CD DSP sub-code pin. This allows the
system microcontroller to read the sub-code values.
The system microcontroller can access buffer RAM
through the LC89517K.
Pseudo-SRAM support (An interface circuit is built in.)
