Swissbit Product Features


Swissbit’s EM-20/EM-26 e.MMC fulfills the JEDEC 5.0 Standard and offers a reliable and stable storage product with true industrial operating
temperature. The page based flash management enables both a high performance and high write endurance. Read disturb management
eliminates risk of data loss for read intensive application and makes the EM-20/EM-26 ideal for application like POS/POI, PLC, IoT, gaming,
medical, or as a general boot medium for embedded applications.
The EM-20 allows to configure the MLC storage with multiple MLC, pSLC or mixed partitions.
The EM-26 will be pre-configured in 100% Reliable/pSLC mode.
