Small capacity e.MMC and SD memory cards are cost-efficient for green IIoT
Swissbit has introduced cost-efficient, small capacity e.MMCs and SD memory cards for IIoT and smart city applications. The EM-30 and S-56(u) series are based on 3D TLC NAND and have capacities from 4Gbyte.
The EM-30 and S-56(u) series are available as an embedded component in the form of an e.MMC or as flexible, interchangeable SD memory cards. They also guarantee data security said Swissbit.
The EM-30 product series (153 ball BGA) complies with e.MMC-5.1 specifications and is fully backwards compatible. It is designed for an extended temperature range of -40 to +85 degrees C and is suitable for use in harsh environmental conditions. Based on durable industrial-grade 3D-TLC-NAND and with storage capacities ranging from 4.0 to 8Gbyte, the range offers sequential data rates of up to 280Mbyte per second read and 120Mbyte per second write, as well as 11k IOPS random read and 16k IOPS random write.
The S-56(u) SD and microSD memory cards attain sequential read and write data rates of 95Mbytes per second and 74Mbytes per second, respectively. Random read IOPS is 2,200 and random write IOPS is 1,300. Over-provisioning and pSLC technology ensure the S-56 series offers the highest 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, reported Swissbit.
The cards are suitable for applications which require minimal storage space, for example green IIoT technologies like charging stations, smart meters, and PV inverters. Only a small amount of memory is required to run boot software or to communicate with cloud applications in these instances.
The capacities mean they are suitable for use as boot media or for data logging small amounts of data, without sacrificing performance or durability in green IoT applications such as smart meters, controllers for intelligent building management, or generating and using sustainable energy through charging stations.
Other typical applications for small-capacity flash memory include white goods, payment devices and point-of-sale systems, industrial control systems, and medical diagnostic and patient monitoring devices.
