SBK03 Backup Boot Flash Kit

BBF-16W module + SF100 programmer

The SBK03 lets a board that uses an SO16W (300mil) SPI flash boot from a backup chip instead of the soldered one. The backup sits in DediProg’s BBF-16W 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

Two Ways to Connect

  • The SO16W test clip on the soldered flash
  • A 2.54mm 2×5 BBF connector, if the board was designed with one

What are the typical uses and applications of the SBK03 kit?

  • 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-16W, SO16W (300mil) socket
Programmer SF100, USB
Supported ICs 3.3V and 2.5V only
Speed 1Mbit/s download, 2Mbit/s read
Connection SO16W test clip, 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.

Frequently Asked Questions

1 How does the SBK03 kit streamline the development and debugging process for boot flash?

The SBK03 kit allows you to boot from a backup flash chip, automatically disabling the onboard flash without removal. This enables quick testing of new builds or reverting to known-good configurations using the SF100 programmer, eliminating the need for soldering during development.

2 What specific types of flash memory does the DediProg SBK03 kit support?

The SBK03 kit is designed to work with boards that use an SO16W (300mil) SPI flash. It utilizes the DediProg BBF-16W Backup Boot Flash module for this purpose.

3 Is hardware modification required on my board to use the SBK03 Backup Boot Flash Kit?

No, the SBK03 module is designed to be transparent to the application. When connected, the onboard flash is automatically disabled, and most boards do not require any hardware changes to use the kit.

4 What components are included when purchasing the SBK03 Backup Boot Flash Kit?

The SBK03 Backup Boot Flash Kit includes the BBF-16W module and the SF100 programmer. These components work together to facilitate boot flash backup, restore, and duplication.
