MTFC4GACAJCN-1M WT

Answer: The device uses two separate voltage domains: VCC (NAND core): 2.7V – 3.6V VCCQ (I/O interface): Supports either 1.70V – 1.95V or 2.7V – 3.6V (dual-voltage I/O). Ensure your host matches these voltages – especially VCCQ – to avoid logic level mismatch or damage.

Answer: No. While the pinout and basic commands are compatible, the temperature range is not flexible for industrial environments. Using a commercial-grade part outside its specified range may cause data corruption or early failure. Always verify the suffix: "WT" is required for -40°C to +85°C operation.

Answer: MTFC4GACAJCN-1M WT complies with the JEDEC eMMC 5.1 standard and is backward compatible with eMMC 5.0 and 4.5. It supports HS400 (DDR400, up to 400 MB/s) and HS200 (up to 200 MB/s) interface modes, providing high-speed data transfer for demanding embedded applications.

Answer: The "WT" suffix stands for Wide Temperature grade. This device supports an industrial temperature range of -40°C to +85°C, making it suitable for outdoor, automotive, and industrial applications where extreme temperatures occur.
