Industrial SD

Wide Temp

InnoDisk Wide Temp Industrial SD Card is a slim and low power consumed storage module that designed especially for portable devices. InnoDisk Industrial SD Card is compatible with SD 2.0 standard and supports SDHC Class 10 that provides excellent performance. The built-in auto ECC function can also detect and correct errors during data transfer. Moreover, InnoDisk Industrial SD Card supports standby and sleep mode that reduces power consumption in advance for application with limited power source.

Wide Temperature Industrial Grade SD (Secure Digital) Cards are specifically designed, manufactured and tested to withstand extreme environmental conditions and to improve system reliability and endurance. At the heart of each card there is an advanced microcontroller that performs elaborate Flash modules management including 5 Bytes on-the-fly Error Detection and 4-Bytes Error Correction (EDC/ECC), bad block management (BBM) and extensive wear leveling.

Available in 512MB to 16GB

Selects the highest reliability Single Level Cell (SLC) Flash for its superior endurance. This combination allows achieving 2,000,000 hours for 256MB, 512MB, 1GB, 2GB, 4GB and 8GB capacities.

    Error Detection and Correction

    Highly sophisticated Error Correction Code algorithms are implemented. The ECC unit consists of the Parity Unit (parity-byte generation) and the Syndrome Unit (syndrome-byte computation). This unit implements an algorithm that can correct 28 bits per 1 KB in an ECC block. Code-byte generation during write operations, as well as error detection during read operation, is implemented on the fly without any speed penalties.

    Wear Leveling

    Flash memory can be erased within a limited number of times. This number is called the erase cycle limit or write endurance limit and is defined by the flash array vendor. The erase cycle limit applies to each individual erase block in the flash device. InnoDisk Industrial SD Card uses a wear-leveling algorithm to ensure that consecutive writes of a specific sector are not written physically to the same page and block in the flash. This spreads flash media usage evenly across all pages, thereby extending flash lifetime.

    Bad Blocks Management

    Bad Blocks are blocks that contain one or more invalid bits whose reliability are not guaranteed. The Bad Blocks may be presented while the SD is shipped, or may develop during the life time of the SD. The Bad Blocks will not exceed more than 3% of the total device volume. When the Bad Blocks is detected, it will be flagged, and not be used anymore. The SD implement Bad Blocks management, Bad Blocks replacement, Error Correct Code to avoid data error occurred. The functions will be enabled automatically to transfer data from Bad Blocks to spare blocks, and correct error bit.
