Swissbit extends 3D-TLC-NAND storage options

They are based on 3D-TLC-NAND and optimised for power failure protection, industrial reliability, and high endurance, says the company, which suggests IIoT and smart city applications.

e.MMC EM-30

Taking the two products in turn, the Swissbit EM-30 (153 ball BGA) complies with e.MMC-5.1 specifications and is backward compatible. It is designed for an extended temperature range of -40°C to 85°C, suitable for use in harsh environmental conditions.

Based on industrial-grade 3D-TLC-NAND and with storage capacities ranging from 4GB to 8GB, the range offers sequential data rates of up to 280MB/s read and 120MB/s write, as well as 11k IOPS random read and 16k IOPS random write.

S-56(u)

For the S-56(u) SD and microSD memory cards, they support sequential read and write data rates of 95 MB/s and 74 MB/s, respectively.

The cards are optimized for high-performance applications with random read IOPS of 2,200 and random write IOPS of 1,300. With over-provisioning and pSLC technology, the S-56 series offers high endurance for write-intensive workloads.

“Combined with up to 100,000 PE cycles, its endurance for small data logging even surpasses that of an SLC card for the first time,” writes the company.

Boot media

“With capacities ranging from 4 to 8GB, these are ideally suited as boot media or for data logging of small amounts of data, without sacrificing performance or durability, states the company.

“The models of the EM-30 and S-56(u) series, which are available as an embedded component in the form of an e.MMC or as flexible, interchangeable SD memory cards, offer maximum reliability due to proven firmware architecture. They also guarantee 100% data security.”
