SAA7390GP規(guī)格書詳情
GENERAL DESCRIPTION
The SAA7390 is a high integration ASIC that incorporates all of the logic necessary to connect a CD-60 based decoder to a SCSI or ATAPI host. It also supports a data path from the host to the CDCEP (compact disc encoder) for CD-R applications. An 80C32 microcontroller and a 53CF94/92A (or an ATAPI interface device) are required to provide the full block encode/decode functions.
