Memory IC Procurement Notes

Verify the specific package variant (SOP8 or USON8) required for your design, as the base part number covers multiple physical packages. Confirm the temperature grade matches your operational environment requirements. Ensure compatibility with your system's voltage levels and SPI interface timing constraints before finalizing procurement. Cross-reference the manufacturer's latest datasheet for any updates to command sets or electrical specifications.

Memory IC Selection Notes

Select this component when a 2 Mbit capacity is sufficient for code or data storage needs. It is suitable for applications requiring low power consumption and high reliability. Consider the Quad SPI capability if higher data throughput is necessary compared to standard SPI. Evaluate the available package options against your PCB space constraints and assembly requirements.

Memory IC FAQ

What is the difference between the HOLD# and WP# pins?

The HOLD# pin pauses serial communication without deselecting the chip, while the WP# pin provides hardware-based write protection for the memory array and status register.

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 bidirectional I/O pins (IO2 and IO3) to support Quad SPI operations.
