OVERVIEW

The CL-CR3430 is the newest addition to the

Cirrus Logic family of high-performance ATAPI

CD-ROM decoders, supporting disc speeds up to 45 .

In addition, it also supports the latest addition to the

ATA interface speciﬁcation, Ultra DMA/33, allowing

host speeds up to 33.3 Mbytes/sec.

This device is ﬁrmware compatible with all Cirrus Logic

CD-ROM and CD-R/RW products, allowing customers

to upgrade quickly and efﬁciently. In a system, the

CL-CR3430 is conﬁgured with an external buffer

memory (8- or 16-bit DRAM), a local microcontroller,

and system RAM and ROM to create a complete

CD-ROM solution.

Other performance features include support for 16-bit-

wide DRAMs. This feature allows the CL-CR3430 to

support PIO Mode 4 without turning on IOCHRDY.
