Features:
- The card supports error correction.
- Wear leveling is implemented in the flash memory system.
- Power-loss protection is provided.
Read and write operations on 6ES7648-2BF10-0XH0 have different maximum transfer rates. The two limits describe opposite data directions and are not an interchangeable single throughput rating.
A real-time-capable storage function is specified for 6ES7648-2BF10-0XH0. Boot support and diagnostics are additional card capabilities, rather than different capacity options.
The usable installation context for 6ES7648-2BF10-0XH0 is a SIMATIC device with the corresponding slot. A matching storage capacity alone does not define the required card connection.
The Siemens 6ES7648-2BF10-0XH0 SIMATIC CFast Memory Card may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
Separate startup support from storage access
- Boot operation: The card can serve as a bootable medium in the host device.
- Runtime access: Read and write transfers are available after the host has started.
- Diagnostics: Diagnostic capability is included at card level.
- Slot selection: The host must provide the corresponding CFast slot; the product is not identified as an SD card.
Treat capacity and endurance as different limits
- Write workload: Cumulative written data measures repeated writes over use, not the size of one stored file.
- Free space: Leaving some memory unused is recommended for overall performance.
- Stored data: The retention specification concerns how long data is retained, rather than a permitted write frequency.
- Cell management: The storage controller manages data across flash memory instead of treating endurance as an unlimited property.
Apply the operating and storage conditions separately
- Powered use: The operating-temperature range applies in any mounting position.
- Unpowered storage: The wider storage-temperature range is not an extension of the operating range.
- Moisture: The humidity limit excludes condensation.
- Thermal limits: Both the lower and upper operating limits apply to the card during use.
Distinct requirements for electromagnetic and material compliance
- EMC scope: The card is included in the EMC component scope of the Siemens declaration of conformity.
- Immunity: The EMC scope includes immunity standards for industrial and residential environments.
- Emissions: Emission standards are listed separately from immunity requirements in the EMC scope.
- RoHS scope: The card is also listed in the RoHS component scope, with EN IEC 63000 used for the material-compliance assessment.
