Memory IC Procurement Notes

Verify the specific package variant (SOP8, TSSOP8, USON8) required for your design, as the datasheet lists multiple options. Confirm temperature grade availability (Commercial or Industrial). Check for end-of-life status or recommended new designs notices directly from BYTe Semiconductor before finalizing procurement plans.

Memory IC Selection Notes

Select this component when an 8M-bit capacity is needed with support for high-speed Quad SPI operations. Ensure the system voltage falls within the 1.65V to 3.6V range. Consider the available package types such as SOP8 or USON8 based on board space constraints. Verify that the required operating temperature range matches the Commercial or Industrial grades specified.

Memory IC FAQ

What is the maximum clock rate for Fast Read operations?

The maximum clock rate for Fast Read operations is 100MHz.

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

When the QE bit is set to 1, the /WP and /HOLD pins function as IO2 and IO3 respectively for Quad SPI input and output.

What is the page size for programming operations?

The default page size is 256 bytes, but it can be configured to 512 bytes by setting the Dual Page (DP) bit in Status Register 3.
