With the SM2262 and SM2263 series, the company provides PCIe G3 x 4 Lanes NVMe 1.3 controllers while supporting the latest 3D NAND from the main flash manufacturers. The SM2262EN, an high performance SSD controller solution, delivers sequential read and write transfer speeds of up to 3,500 and 3,000MB/s, respectively, and random read and write IO/s of up to 370,000 and 300,000.

The SM2263 is targeted at mainstream client applications and features sequential read and write speeds of up to 2,400 and 1,700MB/s respectively. The SM2263XT, a DRAM-less controller solution, reduces BOM cost and form factor without compromising performance while enabling 11.5x13mm BGA SSDs suited for 2-in-1 systems, chromebooks and mobile devices.

“Demand for ultra-high performance and reliability is growing as PCIe NVMe SSDs are becoming the standard across a wide range of market sectors, from data centers and cloud services to small form factor client devices and industrial, automotive applications,” said Wallace C. Kou, president and CEO, Silicon Motion. “Silicon Motion is leading the field in the drive to create next-generation controller solutions that not only meet today’s needs, but will fulfil the requirements of the world’s leading technology manufacturers far into the future.“

The expanded line-up of turnkey SSD controller solutions meets the range of market requirements, from high-end, high-performance enterprise SSDs to compact SSDs embedded in portable devices and SSDs for use in industrial and automotive applications. These SSD controllers support the latest 3D NAND products from all the main NAND flash manufacturers and are supplied with a suite of SSD controller firmware, providing customers with the assurance of a rapid time to market with new SSD products. All the controller solutions incorporate company’s technologies including end-to-end data path protection, SRAM ECC, NANDXtend technology, and offer high performance with low power consumption.

High speed solutions: SM2262EN and SM2262
PCIe Gen3 x 4 Lanes NVMe 1.3 SSD controllers
The SM2262 series offers the performance for demanding client applications. The controllers are supplied with a suite of controller firmware for integration into SSD product designs. With low-power design, the SM2262EN and SM2262 deliver low power consumption whether in low power or active states.

Both the SM2262EN and SM2262 offer four lanes of 8Gb/s PCIe data flow and eight NAND channels. The SM2262EN devices offer a maximum sequential read speed of 3.5GB/s and sequential write speed of 3.0GB/s.

For mainstream and small form factor performance solutions:

The SM2263XT supports DRAM-less designs enabling SSD manufacturers to produce compact 11.5x13mm BGA SSDs at a lower BoM cost, as well as supporting the Host Memory Buffer (HMB) architecture. The DRAM-less SM2263XT maintains an 2.4GB/s maximum sequential read speed, and a maximum 1.7GB/s sequential write speed.

All these SSD controllers are in volume production.
