Swissbit EN-20 SSD

Swissbit’s EN-20 is a single-chip solution that offers high-speed PCIe SSD performance in a 3.2 cm² BGA package. The device acts as a true industrial-grade SSD with up to 480 GB capacity and four-lane PCIe 3.1/NVMe 1.3 specification. It enables high performance for small-size embedded systems, factory automation, routers and switches, Internet of Things (IoT), cloud computing and medical systems.

The product series features industrial-grade 3D NAND supporting an ambient temperature range from -40 to +85°C. The managed device combines high-grade NAND Flash chips, a sophisticated PCIe controller and firmware that supports demanding applications. The PCIe four-lane interface with backwards compatibility to single- or dual-lane system designs operates according to the latest PCIe 3.1 specification and offers high bandwidth up to 1600 MBps for sequential read and 770 MBps for sequential write. Random performance surpasses 145,000/130,000 IOPS for read and write and nearly doubles the bandwidth of SATA SSDs.

The chip has dimensions of 16 x 20 mm and a 0.8 mm pitch compatible with standard PCB routing guidelines. For low power consumption without sacrificing performance, the product substitutes a local DRAM cache by using the HMB (host memory buffer) feature, which uses system DRAM memory to maintain the flash translation table. Intelligent thermal management protects the long-term stability of the controller and maintains a continuous bandwidth even at highest specified temperatures. Other features include end-to-end data path protection (ETEP), AES 256 encryption, LDPC error correction with full page fail recovery and protection against sudden power loss. Data care management adds extra protection of the stored data at high operating temperatures.
