Memory IC Procurement Notes

Verify the manufacturer designation carefully, as this part number may be associated with Alliance Memory following industry acquisitions. Confirm the exact speed grade suffix and package variant against current official datasheets. Ensure compatibility with existing board layouts regarding the 64-ball BGA pitch and pinout definitions before finalizing procurement decisions.

Memory IC Selection Notes

Select this component when a 256 Mbit capacity with a 16-bit interface is required in a small form factor. Consider the top boot configuration if the application demands immediate execution from the first memory blocks. Evaluate the thermal requirements to ensure the -40°C to +85°C range meets the operational environment standards.

Memory IC Part Context

This part belongs to the PC28F/RC28F series of parallel NOR flash memories. It shares architectural similarities with other devices in the family, such as the JS28F256P30 series, but differs in packaging and specific electrical characteristics. The RC prefix often denotes specific regional or manufacturing variants within the broader Micron memory portfolio.

Memory IC Replacement Considerations

Public confirmed substitute part numbers include JS28F256P33TFE and PC28F256P33TFE. Verify pin-to-pin compatibility and electrical specifications before substitution.
