Cirrus Logic's New CD-Recordable/Erasable Chip Solutions Support Unprecedented CD-ROM Speeds; Cirrus Logic offers the industry's first chip solutions for 18X read and 8X record disc speeds.TOKYO--(BUSINESS WIRE)--Sept. 3, 1996--At a press conference held here today in conjunction with World PC Expo 1996, Cirrus Logic Inc. (Nasdaq: CRUS) introduced the industry's fastest encoder/decoder chips for next generation CD-ROM CD-ROM: see compact disc. CD-ROM in full compact disc read-only memory Type of computer storage medium that is read optically (e.g., by a laser). applications. The new encoders support CD-Recordable/Erasable (CD-R/E) capabilities, which lets the end-user record, erase and re-use the CD. Available in SCSI interface (CL-CR3560) and ATAPI (AT Attachment Packet Interface) The specification for ATA (IDE) tape drives and CD-ROMs. See IDE. ATAPI - AT Attachment Packet Interface interface (CL-CR3460) versions, the encoders also support the industry's fastest 18X read and 8X record disc speeds. "With the emergence of CD-E (Compact Disc-Erasable) The original name for rewritable CDs (CD-RWs). See CD-RW. (Compact Disc Erasable e·ras·a·ble adj. 1. Capable of being erased: erasable ink. 2. Capable of producing something that can be erased: an erasable pen. ) technology, drive manufacturers need CD-R/E chips that are easily implemented and provide leading-edge technology to compete in this growing market," said Nicos Syrimis, general manager of Cirrus Logic's Optical Storage Division. "We designed the CL-CR3560/CR3460 in response to customer demands for a device that supports industry-leading performance while minimizing time-to-market. These two new single-chip solutions integrate most of the functions required to produce a high-performance, cost-effective CD-R/E drive." The new chips are fully compatible with all CD-writing methods giving the end user the freedom to copy and create on all CD-ROM formats. These chips also support Sony-Philips(R) CD-ROM, CD-I (Compact Disc-Interactive) A compact disc format developed by Philips and Sony that held text, audio and animated graphics. It required a CD-I player that contained its own operating system. , and CD-DA (Compact Disc-Digital Audio) The original compact disc format developed by Sony and Philips in the 1980s, which was designed for audio only. Since "CD" is used loosely for all Compact Disc formats, the CD-DA designation differentiates a music disc or player (TM) (Digital Audio) formats, for use with all implementations of CD technology. These highly-integrated, single-chip solutions are equipped with a CD-ROM encoder/decoder, CIRC encoder, EFM (Ethernet in the First Mile) Using Ethernet to provide connectivity from the customer to the carrier.

Implementing ECC in hardware reduces firmware requirements and enhances drive performance by eliminating microcontroller intervention. Cirrus Logic's advanced programmable ECC performs up to 64 P/Q-word corrections per sector and also performs erasure pointer corrections, allowing retrieval of otherwise unrecoverable data. The CL-CR3560/3460 also performs real-time subcode correction in CD-DA mode. Both devices combine fast error correction and the capability to read damaged discs on-the-fly to provide the industry's most advanced data integrity protection. "With this introduction Cirrus Logic underscores its commitment to lead the industry in optical storage technology," said Syrimis. "We combined a sophisticated buffer manager with our advanced ECC support to produce 18X read and 8X record transfer rates, significantly exceeding today's drive requirements. We are also offering our customers a common hardware platform allowing them to develop both SCSI and ATAPI interface CD-R/E drives, reducing the firmware development time effort and improving their time to market." CL-CR3560 The industry's first highly-integrated SCSI interface CD-R/E encoder/decoder. The CL-CR3560 has a single-ended SCSI interface with integrated 48mA bus drivers. The chip supports the SCSI-2 industry standard, making it compatible with a wide variety of peripherals. The CR3560 is also SCAM compatible, conforming to the latest updates of the SCSI specification. CL-CR3460 The CL-CR3460 is the ATAPI equivalent high-performance CD-R/E encoder/decoder. The ATAPI interface permits the CD-ROM to share the ATA (1) (AT Attachment) The specification for IDE drives. See IDE. (2) See analog telephone adapter.

Packaging, Pricing and Availability The CL-CR3560 SCSI and CL-CR3460 ATAPI CD-R/E encoders/decoders are packaged in 128-pin quad flat packs (QFPs). Sample quantities of the CR3560 are available now and the CR3460 will be available in late September. Production quantities will be available at the end of the year, priced at $20 for the CR3560 and $15 for the CR3460 for high-volume.
