Wear Leveling technology
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
o
Write Endurance technology
Due to intelligent wear leveling an even use of the entire flash is guaranteed, regardless how much
“static” (OS) data is stored.
o
Read Disturb Management
The read commands are monitored and the content is refreshed when critical levels have occurred
o
Data Care Management
The interruptible background process maintain the user data for Read Disturb effects or Retention
degradation due to high temperature effects
o
Near miss ECC technology
Minimize the risk of uncorrectable bit failure over the product life time. Each read command analyzes
the ECC margin level and refresh data if necessary
o
Diagnostic features with Life Time Monitoring tool support
High reliability
o
Designed for industrial market especially read intensive application like navigation, infotainment,
POS/POI, Medical and general boot medium use case:
The product is optimized for long life cycle that requires good data retention because of high
temperature mission profile.
o
Intensive write application should use the S-450u series cards
o
Number of card insertions/removals up to 20,000
o
Extended and Industrial Temperature range -25° up to 85°C and -40° up to 85°C, respectively
o
SIP (System In Package) process for extreme dust, water and ESD proof
Controlled BOM & PCN process
Customized options like CID registers, CPRM keys, firmware incl. settings and marking by projects

3. 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 and UHS-I card modes
SPI mode
The micro SD Memory Card also supports SD Default and High Speed mode with up to 50MHz clock frequency
as well as UHS-I modes DDR50, SDR12/25/50 with up to 100MHz 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 40 defect bits per 1kByte.
The controller performs control read operations and checks the consistence of the data. If an error of some bits is
detected, the card refreshes all data in the flash cells to prevent data retention problems.
The card has a power-loss management feature to prevent data corruption after power-down.
The cards are RoHS compliant and lead-free.
1.3 System Performance
S-45u cards are optimized for Random write performance (slightly changes possible).
