IN Brief:
- Firmware can be adjusted for workload behaviour, power consumption, system integration, and application-specific write patterns.
- Optional functions include S.M.A.R.T. monitoring, hardware write protection, secure erase, and identifier and capacity configuration.
- The range includes 3D TLC capacities up to 256GB and wide-temperature 3D pSLC variants rated from −40°C to 85°C.
UD Info has introduced industrial SD and microSD card configurations built around firmware customisation, fixed bills of materials, and long-term supply commitments rather than consumer storage specifications alone.
The Taiwan-based manufacturer is offering 3D TLC products with capacities up to 256GB and 3D pSLC options for write-intensive or harsh-environment systems. Customer samples are scheduled to become available during August.
Industrial removable storage is rarely selected on capacity and interface alone. Controller choice, NAND revision, firmware behaviour, power-loss response, endurance, temperature range, and error handling can change how a card performs inside an embedded system even when two products carry the same headline specification.
UD Info is addressing that problem by offering firmware-level configuration for customer workloads and integration requirements. The company identifies power consumption and write behaviour as variables that can be adjusted for applications such as aerial inspection, mapping, surveillance, and field data collection, where interrupted writes or unstable logging can undermine the value of the system.
The cards can also be configured with product and vendor identifiers, logical-block-address settings, S.M.A.R.T. health monitoring, hardware write protection, and secure erase. These functions cover system recognition, predictable capacity presentation, maintenance planning, protection against unwanted modification, and controlled data sanitisation.
Fixed bill-of-materials support is particularly important for equipment that remains in production for several years. Consumer memory cards can change NAND, controller, or firmware revision without the notice and requalification process expected in industrial electronics, creating the possibility that a replacement behaves differently while retaining the same commercial name.
For an embedded-system manufacturer, such changes can trigger repeated validation work or expose faults only after units enter service. A fixed configuration reduces that variability, although the commitment depends on the storage supplier securing compatible components and managing obsolescence across the promised product life.
The 3D pSLC range is intended for heavier write workloads or harsher conditions. Pseudo-single-level-cell operation uses fewer stored states within multi-level NAND, sacrificing usable capacity in exchange for wider voltage margins and greater endurance than conventional TLC operation.
UD Info specifies operation from −40°C to 85°C for the pSLC series. SD and embedded microSD products rated for temperatures up to 105°C remain under development and should not be treated as part of the currently sampled range.
Temperature rating is only one part of storage qualification. Sustained write performance, write amplification, bad-block management, retention, power interruption, contact reliability, and the host system’s file handling all influence field behaviour. A wide-temperature card can still fail an application if its firmware does not match the workload or if power is removed during a vulnerable operation.
Health monitoring can support condition-based maintenance, provided the reported indicators are documented and interpreted consistently. Proprietary values are of limited use when operators cannot relate them to remaining endurance, error counts, spare blocks, or actual workload exposure.
Hardware write protection and secure erase address different risks. Write protection can preserve configuration or evidential data against accidental or unauthorised changes, while secure erase is intended to remove stored information before maintenance, reassignment, or disposal. Both functions need system-level verification rather than acceptance from a feature list.
The removable format offers obvious servicing advantages, but it also introduces connectors, card handling, and replacement practices that soldered storage avoids. Designers must decide whether field replacement and standard sockets outweigh the greater physical and configuration control available from eMMC or another fixed device.
UD Info serves industrial automation, transportation, medical, energy, aerospace, and embedded-computing markets, where qualification and continuity can matter more than maximum sequential-transfer figures. Its latest range is positioned around those operating requirements rather than direct competition with retail cards on capacity and price.
The practical measure will be the detail supplied with samples: endurance assumptions, workload definitions, change-notification policy, health-reporting documentation, power-loss behaviour, and the duration of the fixed-BOM commitment. Industrial storage becomes credible when those controls are documented and testable, not merely when a consumer card is relabelled for a harsher environment.
