Marvell has released PCIe SSD controller that features a dual-lane support, 1GB/s data transfer rate, and SATA Express standard compliance.

The 88SS1083 controller also supports Separate RefClock with Independent SSC (SRIS), a critical feature as it eliminates the need for an expensive shielded cable for minimising noise and instead allows for a cost-effective SATA Express cable. SATA Express host can connect either high-performance SATA Express SSDs or traditional SATA devices at similar accessory costs.

In addition to SATA Express compliance, the controller is designed with 28nm low-power process technology, minimising its power consumption. It supports several power level management including DevSleep and L1.2 PCIe low power state, allowing devices to be always on and always connected without reducing battery life. Additionally, the NAND flash controller design is based on the company's IP and can scale to support 15nm NAND flash.

Other features include SRIS for SATA Express connectivity, IO design for cost-effective cabling and compliance with 2014 PC chipsets, and Gen 2x2 28nmAdvanced NAND flash controller for new 1znm NAND flash and Toggle 2/ONFI 3 at 400MT/s NAND IO support.

The controller is currently sampling to lead customers and is scheduled to be in mass production later this year. There is no available image for the controller as of press time.
