Memory IC Procurement Notes

Verify the specific suffix 'WIG(R)' against the manufacturer's official ordering guide to confirm the exact package type and tape/reel specifications. Ensure compatibility with the required operating temperature range, as industrial grades may have distinct suffixes. Cross-reference the datasheet revision number to validate electrical characteristics and timing parameters before finalizing procurement.

Memory IC Selection Notes

Select this component when a compact 8-pin surface-mount solution is required for 128Mb capacity. Verify that the host controller supports the necessary SPI modes, particularly Quad I/O if maximum throughput is needed. Confirm that the 2.7V to 3.6V supply voltage aligns with the system power rails. Consider the thermal performance of the WSON package relative to the expected active current consumption during read/write cycles.

Memory IC Part Context

This part belongs to the BY25Q128AS family of SPI NOR Flash memories from BYTe Semiconductor. The family offers various packaging options including SOP-8 and WSON-8. The 'WIG' suffix typically denotes the 8-WSON 5x6mm package variant. This series is designed for cost-sensitive applications requiring reliable data retention and moderate speed performance.
