SBK05 Backup Boot Flash Kit
BBF-D8W dual-socket module + SF100 programmer
The SBK05 is for boards that carry two SO8W (207mil) SPI flash devices. Both backup chips sit in DediProg’s BBF-D8W Backup Boot Flash module. When it is connected, the board boots from them and the two onboard flash chips are disabled automatically, with no need to remove them. 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 chips, 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
- Dual serial flash emulator, transparent to the application
- Disables the onboard serial flash automatically, with no need to remove them
- 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 dual BBF test clip on the two soldered flash chips
- Two SMT 1.27mm headers soldered in place of the flash footprints, with the dual-header cable adaptor
- A 2.54mm 2×5 BBF connector, if the board was designed with one
Typical Uses
- Boards with two SPI flash devices on one SPI bus
- 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-D8W, two SO8W (207mil) sockets |
| Programmer | SF100, USB |
| Supported ICs | 3.3V and 2.5V only |
| Speed | 1Mbit/s download, 2Mbit/s read |
| Connection | Dual test clip, two SMT 1.27mm headers, 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. The two flash devices must share one SPI bus, with separate chip selects |
For offline programming only, a socket adaptor is the better choice than a BBF kit.
