Memory IC Procurement Notes

Verify the specific ordering suffix 'MIG' against official BYTe Semiconductor documentation to confirm package type and temperature grade. Ensure compatibility with host system voltage levels within the 2.7 V to 3.6 V range. Confirm moisture sensitivity handling requirements prior to assembly.

Memory IC Selection Notes

Select this component when 8 Mbit capacity and Quad SPI support are required for high-throughput applications. Consider the 8-pin SOP package for standard surface-mount assembly. Evaluate the need for hardware write protection and security register features for system integrity.

Memory IC Part Context

The BY25Q80ES series belongs to BYTe Semiconductor's SPI NOR Flash family. It provides non-volatile storage with flexible erase structures. The device is designed for cost-effective solutions requiring reliable data retention and endurance in consumer and industrial electronics.

Memory IC Replacement Considerations

Check for direct pin-compatible alternatives within the BY25Q80ES series or other manufacturers' 8 Mbit Quad SPI NOR Flash parts. Verify electrical characteristics, command set compatibility, and package dimensions before substitution.

Memory IC FAQ

What is the maximum clock frequency for Fast Read operations?

The device supports a Fast Read (Serial) clock rate of up to 120 MHz with a 30 pF load.

How is the Quad Enable (QE) bit configured?

The QE bit is a non-volatile bit in Status Register 2. Setting it to 1 enables Quad I/O mode, reassigning /WP and /HOLD pins to IO2 and IO3.

What happens if the /RESET pin is driven low?

Driving the /RESET pin low interrupts any ongoing Program/Erase operations and resets the device to its initial power-on state. Data corruption may occur if operations are interrupted.
