Marvell today announced the launch of its new 88SS1083 PCI Express (PCIe) solid state drive (SSD) controller -a two-lane PCIe Gen2 SSD controller. With performance transfer rates up to 1 GB/s, Marvell's 88SS1083 controller allows SSD manufacturers to offer PCIe SSD at price parity to SATA SSD. The Marvell 88SS1083 is the industry's first controller to be fully compliant with the SATA Express standard, which leverages the most popular PCIe interface and brings in low latency, dual-lane support and 1 GB/s data transfer rate.
The new 88SS1083 controller also supports Separate RefClock with Independent SSC (SRIS), a critical feature as it eliminates the need for an expensive shielded cable for minimizing 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 new 88SS1083 controller was designed with 28 nm low-power process technology, minimizing its power consumption. As low power becomes a key factor when deploying SSD, the 88SS1083 controller's support for DevSleep and L1.2 PCIe low power state provides another level of power management when the drive is almost completely shut down, allowing devices to be always on and always connected without reducing battery life. Additionally, the NAND flash controller design is based on the well-established Marvell IP and can scale to support 15 nm NAND flash.
Key features of Marvell's new 88SS1083 PCIe SSD controller include:
- New 1 GB/s SATA Express that replaces 6 Gb/s SATA storage
- SRIS for SATA Express connectivity and L1.2 support for ultralow storage power management
- New IO design for cost-effective cabling and compliance with 2014 PC chipsets
- Gen 2x2, 28 nm Advanced NAND flash controller for new 1znm NAND flash and Toggle 2/ONFI 3 at 400 MT/s NAND IO support
The 88SS1083 is currently sampling to lead customers and is scheduled to be in mass production in Q4, 2014.
