Memory IC Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and temperature range. Ensure compatibility with the host system's voltage levels and SPI mode requirements. Confirm moisture sensitivity handling procedures during assembly. Cross-reference the device identification codes with the datasheet to validate authenticity.

Memory IC Selection Notes

Select this component when a 16 Mbit capacity is required with support for high-speed quad I/O operations. Consider the 8-USON package size for space-constrained designs. Evaluate the need for hardware write protection via the WP# pin if security is critical. Ensure the operating environment falls within the specified industrial temperature range.

Memory IC FAQ

How does the Quad Enable bit affect the HOLD function?

When the Quad Enable bit is set to 1, the HOLD function is disabled, and the HOLD# pin acts as a dedicated data I/O pin (IO3).

What is the purpose of the Dummy Configuration bit?

The Dummy Configuration bit selects the number of dummy cycles between the end of the address and the start of read data output to accommodate higher clock frequencies.
