Industrial application environments often face unique challenges, such as power consumption and write behavior, demanding long-term supply support, firmware customization, fixed BOM support, and industrial-grade reliability to address varying application-specific storage requirements.
Designed to support the previously mentioned features for advanced industrial applications, UD info’s SD and microSD card solutions provide 3D TLC capacities from 64GB to 256GB and pSLC capacities from 16GB to 32GB.
UD info’s SD and microSD Card Solutions in Action
The SD and microSD product lines support the BiCS5 5th-generation 3D NAND flash memory technology for high-capacity, high-performance, and low-cost storage capacity. For quick memory card and device communication, the storage solutions are equipped with a Bus Speed Mode of up to UHS-104.
The firmware-level customization is a key differentiator of the SD and microSD solutions, allowing the customer’s workload and system integration needs to be optimized based on firmware behavior.
The storage solutions also support efficient read speeds up to 95MB/s and write speeds up to 85MB/s. The microSD card is equipped with an 8-pin interface, and the SD card with a 9-pin interface, both designed to operate at a maximum frequency of 208MHz, and can alternate communication protocol between the SD mode and SPI mode.
For power consumption, both the SD and microSD support the following:
- Power Up Current < 250uA
- Standby Current < 1mA
- Read Current < 400mA
- Write Current < 400mA
With an estimated low failure rate, the storage solutions also support a Mean Time Between Failures (MTBF) of more than 3,000,000 hours.
The SD and microSD solutions from UD info also provide features for advanced flash management, such as:
- Static and Dynamic Wear Leveling
- Bad Block Management
- SMART
- Auto-Read Refresh
- Embedded Mode
Getting Started with UD info’s SD and microSD Card Solutions
The SD and microSD storage solutions support a supply voltage between 2.7V ~ 3.6V. For the operating temperature ranges, the storage solutions support a standard/gold range of -25°C ~ 85°C, a wide temperature range of -40°C ~ 85°C (only for pSLC), and a storage range of -40°C ~ 85°C.
Optional configuration features include PID/VID customization, LBA customization, S.M.A.R.T. health monitoring, hardware write protection, and secure erase. The advanced, industrial SD and microSD solutions are also RoHS and EMI compliant.
