LONDON STMicroelectronics is planning to make hard disk drive SoCs incorporating entirely its own IP in 90nm technology. The part will integrate the read channel, serial ATA interface (SATA) and memory.
Functional silicon, made at the Crolles2 Alliance’s fab in France, is already being evaluated and tested.
“In-house development of the IP for all the functions of the hard-disk drive system-on-chip places ST in the best position to satisfy the specific requirements of high-performance drive manufacturers,” said Roberto Fantechi, General Manager of ST’s Data Storage Division.
Fantechi said the part will be the first such SoC to reach the market made using 90nm process technology, and will offer increased functionality in the same silicon space.
The company said its 90nm roadmap for firmware-compatible read channels will address the requirements of disk drives at all performance levels for consumer and computing application, with parts available later in the year.
ST’s T90 Read Channel IP supports data rates ranging from 300 Mbit/s up to 1.7 Gbit/s, and, the company says, linked to the SATA performance, the design is optimized for the 2.5-inch and 3.5-inch disk drives used in high-end mobile, desktop computers and servers.
ST announced the successful fabrication of the MiPHY (Multi-Interface PHY) Physical Layer in 90nm, last year.
This macro-cell provides the high-speed SATA interface in the new chip, and can also support applications using the Serial Attached SCSI (SAS), Fiber Channel, and PCI Express serial interface standards, enabling fast design validation for different markets and reducing costs for manufacturers by optimizing engineering resources.
The 90nm HDD SoC design is based on ST’s Tintoretto read-write channel architecture, which enables high data rates with low power dissipation in all HDD operating modes. T90 supports 10-bit high-rate codes and reverse order coding, media noise optimized data detection, advanced defect scan, and longitudinal and perpendicular recording.
