Product Fact Sheet Industrial MICRO SD/SDHC Memory Card **S-46u Series UHS-I Interface, pSLC**
## **S-46u Series (pSLC)**
## **Industrial MICRO SD/SDHC Memory Card – 2/4/8/16 GByte**
## **Main Features**
- Fully compliant with SD Memory Card specification 2.0 and 3.0 and MICRO SD Memory Card Addendum 4.00
- SD/SDHC default/high speed mode and UHS supported
- `o` Up to speed class 10 and U1 according SD3.0 specification `o` FAT16 or FAT32 preformatted
- High performance 3.0 specification
- UHS-I speed 0…100MHz (SDR50), 0…50MHz (DDR50)
- SD High speed 0…50MHz
- SD Default speed 0…25MHz
- Up to 1400MByte/s sequential data rate
- durabit firmware optimized for random write performance, up to 1400 write IOPs (4kB)
- Power Supply: (Low-power CMOS technology)
- 2.7…3.6V normal operating 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
- 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
- Data Care Management
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 analyzes 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:
- The product is optimized for long life cycle that requires good data retention because of high temperature mission profile.
- S-46u cards with pseudo SLC (pSLC) feature higher write performance and endurance than MLC based cards (S-45u) and have a cost advantage over SLC based cards (S-450u)
- Number of card insertions/removals up to 20,000
- 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
