Memory IC Procurement Notes

Verify the specific suffix Y2GY against official datasheets to confirm package dimensions and pinout compatibility. Confirm availability status as supply constraints may affect lead times. Ensure design-in compliance with RoHS3 and REACH regulations prior to procurement.

Memory IC Selection Notes

Select this component when a 1 Gbit density is required in a compact 8-WSON footprint. Consider the 133 MHz speed limit and 2.7V-3.6V operating voltage range against system power rails. Evaluate thermal performance requirements given the +105°C upper operational limit.

Memory IC Part Context

This part belongs to the GD55B series of SPI NOR Flash memories from GigaDevice. The series targets diverse market segments including consumer electronics and automotive systems, offering scalable solutions for embedded designs requiring high reliability and cost-effective storage options.

Memory IC Replacement Considerations

GD55B01GEYIGR: Similar 1 Gbit capacity and WSON-8 package but operates at 133 MHz with a narrower temperature range (-40°C to +85°C). Verify voltage compatibility and interface support before substitution.
