MILPITAS, Calif., June 23 /PRNewswire-FirstCall/ -- LSI Corporation (NYSE: LSI)today announced the TrueStore(R) RC9500, the industry's first40-nanometer (nm) read channel. Now sampling to hard disk drive (HDD)manufacturers, the RC9500 is designed to support notebook throughenterprise HDD form factors and capacity points. The RC9500'snext-generation low-density parity check (LDPC) iterative decodingtechnology enables a greater than 10 percent increase in the datastorage capacity of HDDs, reduces read channel power consumption anddelivers industry-leading performance with data rates exceeding 4.0Gb/s.

"HDD read channel technology is critically important in a diskdrive," said John Rydning, IDC's HDD research director. "Improved readchannels made by companies like LSI enable higher capacity disk drivesthat consume less power. The new LSI(TM) read channel, based on 40nmsemiconductor process technology and using LDPC iterative decodingtechnology, will enable HDD OEMs to reach next-generation HDD capacitypoints."

The RC9500's next-generation LDPC iterative decoding technologydelivers significant improvements in signal-to-noise ratio (SNR),increasing the areal density of stored data. As a result, HDDmanufacturers can eliminate the need to implement other costly designchanges required to reach the next capacity point. The RC9500 alsoincludes features which are designed to reduce firmware complexity,increase drive yields and lower development costs for HDD makers.

The RC9500 offers energy savings enabled by 40nm process technologyand innovative design techniques that provide ultra-low currentconsumption in sleep mode, which is critical to extending battery lifein the notebook market segment. In addition, the lower active powerconsumption can reduce temperatures, improving drive reliability fordesktop and digital video recorder applications, and can translate tosignificant energy cost savings in data center environments.

"The TrueStore RC9500 is built on a revolutionary new architectureand is part of a total recording system design that includes the LSIpreamplifier, customer interconnects, heads and media as part of thecomplete data path solution," said Phil Brace, senior vice presidentand general manager, Storage Peripherals Division, LSI. "No othercompany can offer the breadth of high-performance storage IC productsand systems that LSI delivers."

Designed for hard disk and tape drive applications, the LSITrueStore family of ICs include highly integrated high-performancestorage SoCs, read channels, preamplifiers, serial PHYs and hard diskdrive controller IP. By offering a broad portfolio of integrated SoCsolutions, LSI enables its customers to address all segments of the HDDmarket - from mission-critical enterprise applications andhigh-capacity desktop PCs to low-power laptops and a variety ofconsumer electronic devices.
