Memory IC Procurement Notes

Verify the specific suffix 'WIGR' confirms the WSON-8 6x5mm package and industrial temperature grade (-40°C to +85°C). Confirm the datasheet revision matches the required command set and electrical characteristics. Ensure design compatibility with the 2.7V to 3.6V operating voltage range and 120MHz clock speed limitations.

Memory IC Selection Notes

Select this component when an 8M-bit capacity is required with uniform sector erase architecture. It is suitable for designs needing high-speed read performance up to 120MHz and support for dual/quad I/O operations. Consider the WSON-8 package constraints and industrial temperature rating during PCB layout and thermal management planning.

Memory IC FAQ

What is the difference between Dual SPI and Quad SPI modes?

Dual SPI uses two bidirectional I/O pins (IO0 and IO1) to double the data transfer rate, while Quad SPI utilizes four I/O pins (IO0-IO3) to quadruple the rate. Quad mode requires setting the QE bit in the status register.

How is the memory protected against unintended writes?

Protection is achieved through software commands (Block Protect bits in the Status Register) and hardware control via the WP# pin. The WP# pin can lock the status register or protect specific memory regions depending on configuration.
