ADATA Unveils Industrial-Grade microSD/SD Cards

The ADATA ISDD33K and IUDD33K offer excellent reliability, durability, and performance for industrial applications

Taipei, Taiwan – April 23, 2020 – ADATA Technology (Taiwan Stock Exchange: 3260.TWO), a leading manufacturer of high-performance DRAM modules, NAND Flash products, and mobile accessories today announces the launch of three industrial-grade microSD cards, the ADATA ISDD33K and IUDD33K,  that offer the reliability, durability, and performance required for industrial applications.
The ADATA ISDD33K industrial-grade SD card implements 3D TLC Flash, sports a 3K P/E cycle rating, and read and write speeds of up to 95/70MB per second. The ISDD33K is highly reliable and compatible as well as power efficient, and is ideally suited for applications such as medical devices, surveillance systems, point of sale systems. The ADATA IUDD33K industrial-grade A1 (Application Performance Class 1) microSD card implements 3D TLC Flash, sports a 3K P/E cycle rating, and read and write speeds of up to 95/70MB per second. The IUDD33K is ideally suited for applications such as industrial automation, surveillance systems, and point of sale systems. Both the IUDD33K and ISDD33K support S.M.A.R.T. (Self-Monitoring, Analysis and Reporting Technology), which can indicate imminent failures, and E2E (End-to-End) Data Protection.

Wide Temperature Range, Error Correcting, & Wear Leveling

For excellent durability, both memory cards are built to withstand wide temperature ranges (-40°C to 85°C) to handle even the harshest of operating environments. To prevent errors from occurring during data transfers, the ISDD33K and IUDD33K support LDPC ECC (Low Density Parity Check Error Correcting Code) to enable algorithms to operate in real-time, precisely decode, and improve the quality of data transmissions. Both memory cards also support Wear Leveling, to distribute write/erase cycles evenly among blocks for a longer product lifespan. The cards also implemented V10 capabilities denoting at least 10MB/s of video recording bandwidth for high-resolution video recording.


ADATA’s Proprietary A+SLC Technology

For reliability and improved cost efficiency, these memory cards implement ADATA’s proprietary A+SLC technology. It utilizes custom NAND Flash firmware with an A+ sorting algorithm to emulate SLC performance. A+SLC is highly reliable, provides excellent data integrity, and delivers a superb cost/performance balance.
