DediProg岱鐠 備用開機 Flash 模組-SO8W(207mil) 支援 Quad IO

Description

The Backup Boot Flash QUAD (BBF-QUAD-8W) is an ingenious tool created by DediProg to allow the application controller to work on the backup SPI Flash inserted in our tool SO8W socket. It allows the application controller to access the backup SPI Flash with SPI single/Dual/Quad IO mode.

The BBF-QUAD tool can be connected to the application with:

• Our BBF cable (included) to the application 2X5 2.54mm pin header.
• Our BBF cable (included) to our SMT 1.27mm Pin Header (included) is soldered in place of the Main Serial flash footprint for a better stability.

The Serial Flash can be easily changed manually thanks to the SO8W socket or even updated by connecting our SF100 or SF600 programmer. The SF100/SF600 programmer is completely transparent for the application and will offer to developer high flexibility for code trials or update. When using BBF-Quad on a board, the soldered spi flash needs to be removed.

• Support 3.3V~1.8V SOP8W SPI NOR Flash
• Support Quad IO R/W between Backup Serial Flash and application board
• Backup Serial Flash can be easily updated by connecting the SF100/SF600 programmer

For offline programming demand only, it is recommended to use a socket adaptor.
