Product Lineup
NEC Electronics provides PHY cores (supporting 3 Gbps), link/transport layer cores, and application layer cores. All of which are compliant with Serial ATA1.0a/Serial ATA-II Rev.1.2. Therefore, we could offer customers SATA IP core solution that enables both system optimization and short development TAT.
Features of NEC Electronics' Cores
- Compliant with SerialATA1.0/SerialATA-II. The cores are developed through applying the draft specifications in advance (support of SSC (spread spectrum clocking), NCQ, etc.).
- Provision for physical layer (PHY), link layer (Link), transport layer (Transport), and even up to application layer in some cases.
- Application-based cores archived.
Example of Supplied Cores
Serial ATA PHY (physical layer) core
A Serial ATA-II-compliant 1- to 8-channel PHY core (hardware core) with a transfer rate of 3.0 Gbps, currently supplied on a CB12 process chip. The version of 90nm process will be supplied from FY2006 1Q.
Serial ATA transport I/F core
A transport I/F core that combines the above PHY core with a software core that consists of a host-side link layer, transport layer, and registers. Ideal for customers who develop their own application layers (DMA, I/F control, etc.).
Serial ATA Register I/F core (Expected to be released in FY2006/1Q)
Application layer (control register, FIFO, PIO, and IF controls) has been combined with transport interface whereby customer only need to add DMA controller and on-chip bus to bus interface to centralize the Serial ATA functions.
