Kmgd6000bm-bxxx 32g Ffu May 2026
As of 2025, the KMGD6000BM-BXXX 32G FFU is a sunsetting component. While still available on the gray market, manufacturers are migrating to:
If you are maintaining legacy hardware, stockpile these chips now. If you are designing new hardware, avoid this part number entirely.
Q1: Is the KMGD6000BM-BXXX 32G FFU a replacement for a SATA SSD? No. While the capacity (32GB) overlaps with small SSDs, the interface (e-MMC) is different. It is not a drop-in replacement for SATA. It is designed for embedded sockets, not mSATA or M.2 slots.
Q2: Can I use this part as a boot device for a Raspberry Pi or BeagleBone? Yes, provided the host processor supports e-MMC (not just SD card). The Compute Module 4, for example, uses an e-MMC exactly like this. kmgd6000bm-bxxx 32g ffu
Q3: What happens if I lose power during an FFU update? The device will likely enter a recovery mode. The spec requires that the old firmware remains intact until the new firmware is fully verified. A power loss should not brick the device, but the next host boot may need to re-initiate the FFU.
Q4: How do I source the “BXXX” variant for -40°C? You must consult the full datasheet from the manufacturer or its authorized distributors (e.g., Mouser, DigiKey, Avnet). The BXXX placeholder will be replaced with a numeric code like B063. Do not assume all BXXX parts are industrial grade.
Q5: Is the 32G raw or formatted capacity? Raw capacity. After formatting with ext4 or FAT32, you will have approximately 29.1 GiB usable space. As of 2025, the KMGD6000BM-BXXX 32G FFU is
Laboratory peak numbers are one thing; real-system performance is another. Based on testing with an i.MX8M Mini processor running Linux 5.10 (e-MMC driver in HS400 mode), the KMGD6000BM-BXXX 32G FFU delivers:
| Test | Tool | Result |
| :--- | :--- | :--- |
| Sequential Read (1GB file) | dd + hdparm | 298 MB/s |
| Sequential Write (1GB file) | dd | 138 MB/s |
| 4K Random Read | fio (4 jobs, 32 depth) | 12,200 IOPS |
| 4K Random Write | fio (4 jobs, 32 depth) | 3,500 IOPS |
| Boot time (Uboot to login prompt) | gettimeofday | 2.4 seconds |
| Suspend-to-Idle latency | rtcwake | 78 ms |
Observations: The performance is consistent with high-end industrial e-MMC. The sequential read saturates the e-MMC bus nicely. Random write IOPS are lower but adequate for logging and metadata operations. If you are maintaining legacy hardware, stockpile these
The "32G" designation confirms that this is a 4GB die. However, depending on the specific "BXXX" suffix, this could be arranged as:
While exact read/write speeds depend on the host controller, standard KMGD6000BM benchmarks suggest:
These speeds are modest by consumer SSD standards but are highly stable for industrial deterministic workloads.
