SBK01 Backup Boot Flash Kit
BBF-8W module + SF100 programmer
The SBK01 lets a board that uses an SO8W (207mil) SPI flash boot from a backup chip instead of the soldered one. The backup sits in DediProg’s BBF-8W Backup Boot Flash module. When it is connected, the onboard flash is disabled automatically, with no need to remove it. The module is transparent to the application, and most boards need no hardware change.
The SF100 programmer in the kit writes new images to the backup flash, so you can try a new build or go back to a known-good one without touching a soldering iron. The kit is also often used to boot a PC or board whose BIOS update failed, and then repair the corrupted BIOS with the usual flash utility tools.
Highlights
- Serial flash emulator, transparent to the application
- Disables the onboard serial flash automatically, with no need to remove it
- No hardware change needed on most boards
- Image download at 1Mbit/s, read at 2Mbit/s
- USB interface with signal conflict protection
Three Ways to Connect
- The BBF test clip on the soldered flash
- An SMT 1.27mm header soldered in place of the flash footprint, for a steadier connection
- A 2.54mm 2×5 BBF connector, if the board was designed with one
Typical Uses
- Booting a failing PC or board and repairing a corrupted BIOS
- Trying new firmware builds without reflashing the soldered chip
Key Specifications
| Spec | Value |
|---|---|
| Backup flash module | BBF-8W, SO8W (207mil) socket |
| Programmer | SF100, USB |
| Supported ICs | 3.3V and 2.5V only |
| Speed | 1Mbit/s download, 2Mbit/s read |
| Connection | Test clip, SMT 1.27mm header, or 2.54mm 2×5 BBF connector |
| Board requirement | Pull-up resistor between the HOLD pin and Vcc when the onboard flash stays on the board |
For offline programming only, a socket adaptor is the better choice than a BBF kit.
