Marvell today launched its new 88SS1083 PCI Express (PCIe) solid state drive (SSD) controller - the 88SS1083 two-lane PCIe Gen2 SSD controller.
The new chip offers performance transfer rates up to 1 GB/s, allowing SSD manufacturers to offer PCIe SSD at price parity to SATA SSD. The Marvell 88SS1083 is among the first controllers 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 feature that 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 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 Marvell IP and can scale to support 15 nm NAND flash.
The 88SS1083 is currently sampling to Marvell'a customers and is scheduled to be in mass production in Q4, 2014.
