Memory IC Procurement Notes

Verify the specific package suffix 'BJRY' against official GigaDevice ordering information, as datasheet documentation primarily lists SOP8, WSON8, and TFBGA packages. Confirm availability through authorized distributors, as supply status may vary. Ensure compatibility with host system voltage levels and interface requirements before procurement.

Memory IC Selection Notes

Select this component for applications requiring high-speed Quad SPI access and robust data protection features. Consider the available package options such as SOP8 or WSON8 based on board space constraints. Verify that the host controller supports the required SPI modes and dummy cycle configurations for optimal performance at 133 MHz.

Memory IC FAQ

How does the Quad Enable (QE) bit affect pin functionality?

When the QE bit is set to 1, the WP# and HOLD#/RESET# pins function as bidirectional I/O pins (IO2 and IO3) for Quad SPI operations. When QE is 0, these pins retain their dedicated hardware functions.

What is the purpose of the Dummy Configuration (DC) bit?

The DC bit configures the number of dummy cycles between address output and data readout. This adjustment is necessary to maintain signal integrity and proper timing at higher clock frequencies, such as 133 MHz.
