Swissbit EN-20 Miniaturized Reliable PCIe M.2 BGA SSD for Small Industrial Applications
From 15GB to 240GB in TLC version, and with 5GB to 80GB for EN-26, extension to 480/160GB to follow later this year
This is a Press Release edited by StorageNewsletter.com on August 14, 2020 at 2:15 pmSwissbit AG launches EN-20, a single chip solution which offers high speed PCIe SSD performance in a 3.2cm2 BGA package.
The device acts as an industrial grade SSD with up to 480GB capacity and 4 lane PCIe 3.1/NVMe 1.3 spec. It enables performance and reliability for small size embedded systems, factory automation, routers and switches, IoT, cloud computing, and medical systems.
The EN-20 product series features industrial grade 3D NAND supporting an ambient temperature range from -40°C to 85°C. The managed device combines high grade NAND flash chips, a PCIe controller and firmware that supports demanding applications. The PCIe 4 lane interface with backwards compatibility to single or dual lane system designs operates according to the latest PCIe 3.1 spec and offers bandwidth up to 1,600MB/s for sequential read and 770MB/s for sequential write. Random performance surpasses 145,000/130,000IO/s for read and write and nearly doubles the bandwidth of SATA SSDs.
The single chip has a dimension of 16x20mm and a 0.8mm pitch compatible with standard PCB routing guidelines. For low power consumption without sacrificing performance, EN-20 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 reliability and security features are End-to-End Data Path Protection (ETEP), AES 256 encryption, LDPC error correction with page fail recovery and a protection vs. sudden power loss. Data care management adds extra protection of the stored data at high operating temperatures.
The NVMe protocol has been designed to use the bandwidth with a native nonvolatile memory command set resulting in ultra-low latency.
EN-20 offers a performance, reliability, cost efficient, true industrial SSD in a single BGA chip with up to one DWPD endurance. For even higher endurance requirements, EN-26 in full pSLC mode provides a 10-fold endurance.
EN-20 has been qualified by industrial customers and is available with densities from 15GB to 240GB in the TLC version and with 5GB to 80GB for EN-26.
An extension to 480/160GB will follow later this year.
The small size and integrated metal heat spreader allows the use of EN-20 as a single BGA device and also on a variety of M.2 module form factors from a 2230 length to the standard 2280 variant. EN-20 also powers the soon to be introduced the company’s G-20 CFexpress cards with the same extensive feature set.
