o Up to 24MByte/sec sequential data rate (MLC)
Power Supply: (Low-power CMOS technology)
o 2.7…3.6V normal operating voltage
o 2.0…3.6V basic communication (CMD0, 15, 55 ACMD41) voltage
Standard MICRO SD Memory Card form factor
o 15.0mm x 11.0mm x 0.7mm(1.0mm)
Optimized FW algorithms especially for high read access and long data retention applications
o Patented power-off reliability technology
o 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
o The product is optimized for long life cycle that require a good data retention because of high
temperature mission profile.
o Intensive write application should use the S-4x0u 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
o Selected AEC-Q100 qualification
Controlled BOM & PCN process
Manufactured in a TS 16949 certified factory
Customized options like CID registers, CPRM keys, firmware incl. settings and marking by projects
