Frequently Asked Questions

How much data can the industrial data logger store?

The industrial data logger storage capacity depends on configuration: (1) Single DS35X04G - 512MB (4Gb) raw capacity, approximately 400-450MB usable with file system overhead. (2) Multiple Devices - Can parallel multiple NAND devices for higher capacity. (3) Data Compression - Implement compression to increase effective capacity by 2-3x for text data. (4) Logging Rate - At 1KB/minute logging rate, single device stores ~300 days of data. (5) Circular Buffer - Overwrite oldest data when full for continuous operation. (6) External Storage - Provide interface for periodic data offload to external storage. For most industrial applications, 512MB provides several months to years of data storage depending on sampling rate.

Contact LiTong for storage capacity planning and data retention analysis.

How reliable is the data storage in harsh environments?

Industrial data logger reliability in harsh environments: (1) Temperature - DS35X04G operates reliably from -40°C to +85°C. Tested for temperature cycling and thermal shock. (2) Humidity - Standard packages withstand high humidity

conformal coating recommended for extreme conditions. (3) Vibration - WSON package withstands industrial vibration levels. (4) EMI - Good EMC performance with proper PCB layout and shielding. (5) Data Integrity - 8-bit ECC corrects bit errors

CRC verification provides additional protection. (6) Power Fail - Implement power-fail detection and backup to prevent data corruption. (7) Field Experience - Deployed in factories, outdoor environments, and vehicles with excellent reliability. Expected MTBF >10 years under normal industrial conditions.

Contact LiTong for reliability analysis and environmental testing data.

What file system should I use for the data logger?

File system selection for industrial data logger: (1) UBIFS - Recommended for most applications. Journaling file system with wear leveling, bad block management, and compression. Best for Linux-based systems. (2) JFFS2 - Good for smaller NAND devices. Mature, stable, but less efficient than UBIFS for large devices. (3) LittleFS - Lightweight option for resource-constrained systems. Good wear leveling, low RAM requirements. (4) Custom - Implement circular buffer for simple sequential logging without file system overhead. (5) Selection Criteria: System resources (RAM/CPU), Required features (journaling, compression), OS platform, and Complexity tolerance. For industrial applications, UBIFS or JFFS2 recommended for robustness. LiTong can provide file system integration support.

How do I ensure data integrity during power failures?

Power-fail protection for data integrity: (1) Detection - Monitor power supply with supervisor IC to detect impending power loss. Provide early warning before voltage drops. (2) Backup Power - Use supercapacitor or battery to maintain power for shutdown sequence. Size for 50-100ms operation. (3) Software Response - On power-fail interrupt: Complete current write operation, Flush file system buffers, Close open files, Put NAND in safe state. (4) Journaling - Use journaling file system (UBIFS/JFFS2) that can recover from power loss. (5) Data Verification - Implement CRC checks on critical data blocks. Verify data after write. (6) Redundancy - Store critical data in duplicate locations. (7) Testing - Test power-fail behavior under various conditions. With proper design, data integrity can be maintained through power failures.

Contact LiTong for power-fail protection design and implementation.

What is the expected lifetime of the storage system?

Industrial data logger storage lifetime: (1) NAND Endurance - DS35X04G rated for 100,000 program/erase cycles per block. (2) Wear Leveling - File system distributes writes evenly across all blocks. (3) Lifetime Calculation - With 4096 blocks and 100K cycles: 4096 × 100K = 409.6M block writes total. At 1000 block writes/day: ~1120 years theoretical lifetime. (4) Practical Lifetime - Limited by other factors: Data retention (10 years), Operating temperature, and Power-on hours. (5) Realistic Expectation - 10+ years under normal industrial conditions with proper wear leveling. (6) Monitoring - Track bad block count and erase counts to predict remaining life. (7) Replacement - Plan for device replacement after 5-10 years for critical applications. The storage system lifetime typically exceeds product lifecycle.
