Memory IC Procurement Notes

Verify the specific suffix 'IGR' corresponds to the SOP-8 package and commercial temperature grade (-40°C to +85°C). Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure design compatibility with the 2.7V to 3.6V supply voltage requirements and 133MHz interface speed limitations.

Memory IC Selection Notes

Select this component when a 32 Mbit density is required with uniform sector erase capabilities. It is suitable for designs needing high-speed read performance via Quad SPI and robust data protection features. Consider the SOP-8 package constraints and verify that the operating voltage aligns with the system's power supply rails.

Memory IC FAQ

Is the Quad Enable (QE) bit configurable?

No, the QE bit is permanently set to 1 by default and cannot be changed, ensuring IO2 and IO3 pins are always enabled for Quad operations.

What is the typical standby current consumption?

The typical standby current is 12μA, while the deep power-down current is typically 1μA.
