BY25Q80AWUIG(R)

Memory IC Overview

The BY25Q80AW is an 8M-bit SPI NOR Flash memory designed for code shadowing and data storage. It supports Standard, Dual, and Quad SPI interfaces with clock rates up to 100MHz for non-standard reads and 65MHz for normal reads. The device operates on a single supply voltage ranging from 1.65V to 3.6V. Key performance metrics include a typical page program time of 2ms and erase times of 8ms for pages, sectors, blocks, or the entire chip. It features flexible architecture with 4KB sectors and 32/64KB blocks, low power consumption (3mA active, 0.6uA power-down), and robust write protection mechanisms including hardware and software controls.

Memory IC Procurement Notes

Verify the specific package variant required, as the datasheet lists multiple options including SOP8, TSSOP8, and various USON/DFN packages. Confirm the temperature grade (Commercial or Industrial) matches the application environment. Ensure the ordering suffix aligns with the desired pin configuration and packing quantity. Cross-reference the manufacturer ID and device ID during incoming inspection to confirm authenticity.

Memory IC Selection Notes

Select this component when an 8M-bit capacity is needed with high-speed Quad SPI support. Consider the 1.65V-3.6V operating range for compatibility with low-voltage logic systems. Evaluate the need for dual-page programming via the DP bit if higher throughput is required. Ensure the chosen package fits the PCB layout constraints among the available SOP, TSSOP, and USON options.

Memory IC Part Context

The BY25Q80AW belongs to the BY25Q series of SPI NOR Flash memories manufactured by BYTe Semiconductor. This series is characterized by its flexibility in erase block sizes and support for multiple SPI modes. It serves as a direct functional equivalent to other 8M-bit SPI NOR devices in terms of interface and basic operation, though electrical characteristics and package options may vary between manufacturers.

Memory IC Replacement Considerations

Check pinout compatibility and voltage levels when substituting with other 8M-bit SPI NOR flashes. Verify that the replacement device supports the required Quad SPI mode and clock speeds. Ensure the package type matches the existing footprint or allows for re-design.
