  • Description

    The Industrial Grade microSD cards contain high quality NAND Flash and Controllers with integrated ECC and Wear-Leveling Algorithm. This allows you to use them long term and fail-safe. The SIP production process encases the cards completely and protects them against water, dust, choc and vibrations. Every single produced Industrial Grade microSD card is submitted to the Burn-In Test.

    System-In-Package (SiP)

    Thanks to the the SiP production process, all the industrial grade microSD cards from ATP Electronics are completely encased and all the components protected. The cards are waterproof, dustproof, and also resistant to shock and electrostatic discharge.

    Long-term availability

    The Industrial Grade microSD cards have a fixed BOM (Bill Of Material). The individual components of the cards are always the same to guarantee the compability from one delivery to the next. Any changes on the product with be told 3 to 6 months in advance, so the user gets enough time to secure stock or evaluate the new product. Basically, industrial grade memory cards are in this short-lived market much longer available than consumer products.


    The PowerProtector prevents you from any data-loss or writing-mistakes who could appear during a power failure. This standalone solution holds enough power to compensate any voltage variations, makes it independent from Controller and Firmware, and is also insensitive to temperature fluctuations.

    NAND Flash: SLC / MLC / pSLC

    SLC (Single Level Cell) and MLC (Multi Level Cell) are both NAND-based memory technologies. They refer to the structure of Flash memory cells and how many bits each cell can store. SLC NAND stores one bit per cell while MLC NAND stores two bits per cell. The SLC NAND Flash is therefore more reliable: higher durability (number of read and write cycles), faster, power saving.

    MLC (Multi Level Cell) NAND Flash has a lower manufacturing cost versus SLC NAND. It stores more than 1 bit in one cell, which makes it very attractive (higher density for less money). Its durability and reliability are not as high as for SLC. MLC-based products are recommended for price-sensitive industrial projects.

    pSLC is an exclusive firmware solution. The firmware grants to pSLC cards and modules the technical benefits of the SLC at a better price. Endurance, performance and data retention are significantly improved vs MLC.
