In the world of embedded storage, consumer-grade SD cards just don't cut it for mission-critical hardware. When your device sits in a freezing outdoor kiosk or a hot factory floor cabinet, you need "Industrial Grade" reliability.
The SanDisk (Western Digital) SDINBDA6-64G-XI1 is the gold standard for this requirement.
Part of the iNAND® IX EM132 family, this 64GB eMMC 5.1 chip combines the density of modern 3D NAND with the ruggedness required for industrial IoT. If you are designing a high-end Raspberry Pi Compute Module carrier board or an industrial gateway, this is likely the chip on your BOM.
This guide decodes its specs, explains the "XI" vs "XA" trap, and helps you find compatible replacements.

1. Decoding the Part Number
SanDisk part numbers are logical but dense. Here is the breakdown for SDINBDA6-64G-XI1:
| Code Segment | Meaning | Detail |
|---|---|---|
| SDIN | Product | SanDisk iNAND (Embedded Flash Drive). |
| B | NAND Tech | BiCS Gen (Likely BiCS3 3D NAND). |
| D | Family | Industrial / Commercial line. |
| A6 | Controller | Controller Generation / Revision. |
| 64G | Capacity | 64 Gigabytes. |
| XI | Grade | Industrial Wide Temp (-40°C to +85°C). |
| 1 | Packaging | Standard Tray/Reel packaging code. |
2. Technical Specs: The Power of iNAND EM132
The EM132 series was designed to bridge the gap between expensive SLC storage and cheap consumer TLC.
- Interface: eMMC 5.1 (HS400). Capable of sequential read speeds up to 310 MB/s and write speeds up to 150 MB/s.
- SmartSLC Technology: The controller dynamically treats a portion of the TLC NAND as SLC (Single Level Cell). This provides a "burst buffer" for fast writes and improved endurance for OS logging.
- Reliability Features:
- Advanced Wear Leveling: Distributes writes evenly to prevent premature cell death.
- Power Immunity: Protects data integrity during sudden power cuts—a common event in industrial environments.
- Thermal Management: Auto-throttling to prevent overheating in fanless enclosures.
3. Industrial vs. Automotive: The "XI" Suffix
This is the most common mistake buyers make.
- XI (This Part): Industrial Grade. Tested for -40°C to +85°C. Ideal for outdoor IoT, factory automation, and medical devices.
- XA: Automotive Grade. AEC-Q100 qualified. Typically required for applications inside vehicles (Infotainment, ADAS).
- ZA: Extended Automotive. Rated up to +105°C.
The Takeaway: If you are building a medical device or a smart meter, the SDINBDA6-64G-XI1 is perfect (and cheaper than XA). If you are building a car dashboard, you likely need the XA or ZA version.
4. Hardware Considerations: BGA-153
This chip uses the industry-standard JEDEC 153-ball FBGA footprint.
- Dimensions: 11.5mm x 13.0mm x 1.0mm.
- Ball Pitch: 0.5mm.
- Voltage:
- VCC (NAND Core): 2.7V - 3.6V (Typ 3.3V).
- VCCQ (Controller I/O): 1.7V - 1.95V (1.8V High Speed) or 2.7V - 3.6V.
- Compatibility: The footprint is pin-compatible with standard 64GB eMMC chips from Samsung, Micron, and Kioxia, allowing for multi-sourcing on the same PCB layout.
5. Sourcing & Replacements
Supply chains can be volatile. If the SanDisk/WD part is out of stock, these parts are generally functionally equivalent (verify datasheet specifically for temperature):
- Samsung: KLMCG1REWF-B04P (64GB eMMC 5.1, Industrial -40°C~85°C).
- Micron: MTFC64GAJAEDQ-AIT (64GB eMMC, Industrial Grade).
- Swissbit: SFEM064GB2ED1TO-I-6F-111-STD (A robust, true industrial alternative).
Firmware Note: When switching eMMC vendors, ensure your Linux/Android bootloader is not hard-coded to check for a specific Manufacturer ID (MID) in the CID register, or the system might fail to boot.
6. Conclusion
The SanDisk SDINBDA6-64G-XI1 is a premier choice for storage in harsh environments. It offers the massive 64GB capacity needed for modern OS images (Android/Linux) while maintaining the wide temperature tolerance and reliability features of industrial hardware.
