The SanDisk Industrial microSD Card is based on an 8-pin interface designed to operate in a maximum operating frequency of 104 MHz. The interface for SD Card products allows for easy integration into any design, regardless of which type of microprocessor is used. In addition to the interface, SD Card products offer an alternate communication -protocol based on the SPI standard.

6 SanDisk Industrial microSD cards are designed especially for use in mass storage applications. In addition to the mass storage-specific flash memory. SanDisk Industrial microSD cards include an on-board intelligent controller which manages interface protocols; security algorithms for content protection; data storage and retrieval, as well as Error Correction Code (ECC) algorithms; defect handling; power management; wear leveling and clock control.

Chapter 2 describes the physical and mechanical properties of cards in the SanDisk SD Card, Chapter 3 contains the pins and register overview, and Chapter 4 gives a general overview of the SD protocol. Information about SPI Protocol can be referenced in Section 7 of the SDA Physical Layer Specification, Version SD Card Standard SanDisk microSD cards are fully compatible with the SDA Physical Layer Specification, Version This specification is available from the SD Card Association (SDA).

This intelligent (microprocessor) subsystem provides many capabilities not found in other types of memory cards. These capabilities include: Host independence from details of erasing and programming flash memory Sophisticated system for managing defects (analogous to systems found in magnetic disk drives) Sophisticated system for error recovery including a powerful ECC Power management for low power operation Auto read refresh capability to maximize read endurance of the memory Enhanced power immunity to prevent data loss during unexpected power events Technology Independence The 512-byte sector size of a card in the SanDisk Industrial microSD Card is the same as that in an IDE magnetic disk drive.

9 To write or read a sector (or multiple sectors), the host software simply issues a read or write command to the card. The command contains the address and number of sectors to write or read. The host software then waits for the command to complete. The host software does not get involved in the details of how the flash memory is erased, programmed or read. This is extremely important because flash devices are expected to get increasingly complex in the future. Because SanDisk Industrial microSD cards use an intelligent on-board controller, host system software will not need to be updated as new flash memory evolves. In other words, systems that support the microSD Card today will be able to access future SanDisk Industrial microSD cards built with new flash technology without having to update or change host software. Defect and Error Management The SanDisk Industrial microSD Card contains a sophisticated defect and error management system. This system is analogous to the systems found in magnetic disk drives and in many cases offers enhancements.

10 If necessary, SanDisk Industrial microSD Card will rewrite data from a defective sector to a good sector. This is completely transparent to the host and does not consume any user data space. The SanDisk Industrial microSD Card soft error rate specification is much better than the magnetic disk drive specification. In the extremely rare case that a read error does occur, SanDisk Industrial microSD Card has innovative algorithms to recover the data. These defect and error SanDisk iNAND eMMC I/F - Extended TemperatureDatasheet 2016 SanDisk Corporation. 02-05-WW-02-00005 SanDisk Confidential 6 management systems, coupled with the solid state construction, give SanDisk Industrial microSD Card unparalleled reliability. Content Protection A detailed description of the content protection mechanism and related security SD commands can be found in the SD Security Specification from the SDA. All SD security-related commands in the SanDisk Industrial microSD Card operate in the data transfer mode.
