Memory IC Procurement Notes

Verify the specific suffix B85B against official Micron documentation to confirm pinout and electrical characteristics, as variations exist within the P33 series. Confirm the tape and reel quantity matches project requirements. Check for end-of-life status or alternative sourcing options due to potential discontinuation of older StrataFlash models.

Memory IC Selection Notes

Select this part when 128 Mbit non-volatile storage with low voltage operation (1.7V–2.0V) is required. Ensure the system design accommodates the 64-EasyBGA package dimensions. Verify that the parallel interface timing constraints align with the host controller's capabilities for 52 MHz operation.

Memory IC Part Context

This component belongs to the Micron StrataFlash P33 family of embedded flash memories. These devices are designed for applications requiring high performance and low power consumption. The P33 series typically offers flexible block architectures and support for both asynchronous and synchronous interfaces.

Memory IC Replacement Considerations

PC28F128P30B85D TR is a documented substitute within the same family offering similar 128 Mbit capacity and 64-TBGA packaging.
