Wear Leveling: equal wear leveling of static and dynamic data
The wear leveling assures that dynamic data as well as static data is balanced evenly across the memory.
With that the maximum write endurance of the device is guaranteed.
Write Endurance: Due to advanced wear leveling an even use of the entire flash is guaranteed, regardless
how much “static” (OS) data is stored. Example: If the average file size is 10MByte and the total capacity is
8GByte, 48Mio write cycles can be performed.

Product Specification
The MICRO SD Memory Card is a small form factor non-volatile memory card which provides high capacity data
storage. Its aim is to capture, retain and transport data, audio and images, facilitating the transfer of all types of
digital information between a large variety of digital systems.
The card operates in two basic modes:
SD/SDHC card mode
SPI mode
The MICRO SD Memory Card also supports SD High Speed mode with up to 50MHz clock frequency.
The cards are compliant with
SD Memory card Specification Part 1, Physical layer Specification V3.01
SD Memory card Specification Part 2, File System Specification V3.00
SD Memory card Specification Part 3, Security Specification V3.00
MICRO SD Memory Card Addendum V4.00
Simplified specifications are available at
https://www.sdcard.org/downloads/pls/simplified_specs/
The Card has an internal intelligent controller which manages interface protocols, data storage and retrieval as
well as hardware BCH Error Correction Code (ECC), defect handling, diagnostics and clock control.
The advanced wear leveling mechanism assures an equal usage of the Flash memory cells to extend the life time.
The hardware BCH-code ECC allows to detect and correct up to 24 defect bits per 1kByte.
The card has a power-loss management feature to prevent data corruption after power-down. The power
consumption is very low.
The cards are RoHS compliant and lead-free.
