LONDON STMicroelectronics has started sampling 65nm iterative read channel IP for the low-power mobile segment of hard disk drives.
The company says the part's signal-to-noise ratio (SNR) gain is a key enabler for sustaining the industry's aggressive 40 percent compound annual growth rate in storage capacity and decreasing power drain by a smaller percentage compared to existing devices.
The IP, targeted at the mobile sector, is the first in ST's planned Tiziano range of read channel macros, which will also include channels customized for the desktop and enterprise market segments.
The read channel macro is available for integration within 65nm SoC's. ST says the range is being developed in close collaboration with strategic customers to address specific requirements and ensure competitiveness.
Tiziano rounds out the company's range of 65 nm HDD SoC IP allowing ST to provide customers with complete turnkey solutions or a solution utilizing both ST and customer IP.
The third generation of ST's read channels, the Tiziano range supports the latest industry requirements for perpendicular recording, low power, servo detection and demodulation, defect mapping and self servo write.
The range is said to enhance application battery live time and reliability through lower power by utilizing conditional iteration techniques and dynamic voltage control. Iterative decoding is targeted at perpendicular recording enabling significant capacity gains over the previous generation with at least 0.7dB post ECC SNR gain.
