eSD (embedded SD)

High endurance single chip SSD with SD card interface

eSD is an embedded storage device with an SD card interface. It incorporates Hagiwara's unique flash controller that is specially designed for embedded/industrial applications to deliver highly reliable data storage for demanding applications such as robotics, IoT, medical, etc.

 

Benefits

-Industrial Standard
Standard SD Interface
JEDEC Compliant 100-pin BGA package (1mm pitch)

- Lower Total Cost of Ownership
Requalification cost is minimized thanks to long-term availability of SLC NAND flash.

- High Endurance, Longer Data Retention
eSD Incorporates screened, high-quality industrial grade SLC NAND flash.

- Highly Cost-Effective than NOR flash
eSD delivers higher capacity at lower cost and it eliminates the need for a dedicated boot ROM/NOR device on limited PCB real-estate.

- Optimized for industrial application
Hagiwara's proprietary SSD firmware incorporates layers of technology such as Active refresh, Power loss data protection to ensure the data integrity under harsh environment.

- Eliminates unexpected downtime
Health monitoring and diagnostic Software
Windows & Linux API
SD Command set

- Wide Operating Temperature
