• Standard MICRO SD Memory Card form factor
15.0mm x 11.0mm x 0.7mm(1.0mm)
• Optimized FW algorithms especially for high read access and long data retention applications
Patented power-off reliability technology
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
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.
Read Disturb Management
The read commands are monitored and the content is refreshed when critical levels have occurred
Auto Refresh for Data Retention enhancement
The interruptible background process maintain the user data for Read Disturb effects or Retention
degradation due to high temperature effects
Near miss ECC technology
Minimize the risk of uncorrectable bit failure over the product life time. Each read command
analyze the ECC margin level and refresh data if necessary
Diagnostic features with Life Time Monitoring tool support
• High reliability
Designed for industrial market especially read intensive application like navigation, infotainment,
POS/POI, Medical and general boot medium use case:
o The product is optimized for long life cycle that require a good data retention because of
high temperature mission profile.
Intensive write application should use the S-400 series cards
Number of card insertions/removals up to 20,000
Extended Temperature range -25° up to 85°C (Optional -40° up to 85°C)
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
