BGA Device for Embedded Applications: EM-30 from Swissbit Available Now
December 7, 2021 | Swissbit AGEstimated reading time: 2 minutes
Swissbit has extended its range of miniaturized storage solutions with the launch of its EM-30 series with an e.MMC-5.1 standard interface. The BGA device uses industrial grade 3D-NAND and is available in capacities from 16 to 256 GB. With the new series, Swissbit has responded to the increasing demands of embedded systems for ultra-small, vibration-resistant designs with escalating memory capacity requirements. In addition to durability and a temperature range of -40 up to +105 °C, Swissbit’s EM-30 also offers additional features over and above the e.MMC standard. These include a remote secure firmware update option and an extended lifetime expectation, making the EM-30 product series ideal for a wide range of applications that include POS/POI terminals, routers and switches, through to solutions for industrial automation, the Internet of Things (IoT), automotive or medical systems.
The EM-30 product series (153 Ball BGA, 100 ball BGA option available) complies with e.MMC-5.1 specifications and is fully downward compatible. With sequential data rates of up to 300 MB/s for read and 230 MB/s for write as well as 40 and 42 k IOPS for read and write random access, EM-30 delivers the performance of SATA SSDs, but with significantly smaller size requirements and costs.
EM-30 is designed for an industrial temperature range of -40 to +85 °C as standard. Optionally, the e.MMC is also available for an extended temperature range of -40 to +105 °C, designed to meet the requirements of demanding automotive applications.
Predictable service life, data refresh and reliability
Especially for soldered-down components, knowing the expected service life under real conditions is important. EM-30 devices offer the option to access detailed information about the consumption of the write cycles and internal resources via standard access to the e.MMC registers without the need for special access methods or drivers.
In addition, similar to large SSDs, the EM-30 firmware supports automatic background data refresh of read-only areas that for instance occur with boot media. This feature coupled with strong error correction, ensures that data availability is always highly reliable, even if the data has not been accessed under prolonged periods of exposure to high temperatures.
A further special feature is the increased protection against data corruption in the event of sudden power loss, which not only occurs in regions with an unstable power supply, but also typically when handling medical devices or embedded systems.
Flexible configuration
If and when required, EM-30 devices can be partitioned by the user into several TLC and pSLC segments. If the maximum possible endurance of the NAND is required, Swissbit offers an EM-36 variant preconfigured to 100% pSLC. These types are also now available in capacities between 5 and 80 GB.

AI Is the Golden Track Reviving Electronics and PCBs
08/06/2025 | Edy Yu, Chief Editor, ECIO, and the I-Connect007 Editorial TeamRemember 2021? Despite COVID, the electronics industry hit a high. Then came the slide. By 2023, the industry was deep in the red. With inflation, policy shifts, and exchange rate shocks, the problems were long, and the outlook was bleak. Recovery finally appeared in 2024, but it was fragile. Automotive electronics slumped, wireless demand stayed soft, and the ride up was anything but smooth. Yet, amid the uncertainty, one bright track emerged: artificial intelligence (AI).
