Memory IC Procurement Notes

Verify the specific technology type, as sources classify this part as both FeRAM and ReRAM. Confirm the exact package dimensions and pinout against the official datasheet before integration. Ensure the supplier provides valid RoHS compliance documentation. Check for any recent Product Change Notifications that may affect specifications or manufacturing location.

Memory IC Selection Notes

Select this component when a 4 Mbit non-volatile memory solution is required with SPI connectivity. Consider the 5 MHz speed limit for system timing constraints. The 8-SOP package is suitable for space-constrained designs. Verify compatibility with the target system's voltage levels, specifically the 1.65 V minimum requirement.

Memory IC Part Context

This part belongs to the RAMXEED memory portfolio, which includes various FRAM and ReRAM options. It shares the SOP-8 form factor with other models like the MB85RS series but differs in underlying technology and speed characteristics. The product line targets automotive and industrial sectors demanding high endurance and reliability.

Memory IC Replacement Considerations

Direct substitutes include other 4 Mbit SPI ReRAM/FeRAM devices in 8-SOP packages from compatible manufacturers. Verify electrical parameters such as voltage range and clock speed match the original design requirements before substitution.
