MB85RS2MTYPNF-GS-AWE2

Memory IC Overview

The MB85RS2MTYPNF-GS-AWE2 is a 2Mbit (256K x 8) Ferroelectric Random Access Memory (FeRAM) integrated circuit manufactured by RAMXEED. It utilizes a Serial Peripheral Interface (SPI) operating at frequencies up to 50 MHz and supports SPI modes 0 and 3. The device operates within a supply voltage range of 1.8V to 3.6V and functions across an ambient temperature range of -40°C to +125°C. It is housed in an 8-pin plastic SOP package with a lead pitch of 1.27 mm.

Memory IC Procurement Notes

Verify the specific ordering suffix against the datasheet to confirm the package type and shipping form. Ensure compatibility with the target system's SPI clock frequency and voltage levels. Confirm that the component meets the required AEC-Q100 standards if used in automotive applications. Check for any recent product change notifications regarding manufacturing updates.

Memory IC Selection Notes

Select this component when high write endurance and fast write speeds are critical compared to Flash or EEPROM alternatives. It is suitable for applications demanding data retention over extended periods without battery support. Consider the 8-pin SOP package constraints for PCB layout. Verify that the host microcontroller supports the required SPI modes and voltage levels.

Memory IC Part Context

This part belongs to the MB85RS2MTY series of FeRAM devices from RAMXEED, formerly Fujitsu Semiconductor Memory Solutions Limited. The series is designed for high-reliability applications where data integrity and speed are paramount. The MB85RS2MTYPNF-GS-AWE2 specifically denotes the tube packaging variant of the 8-pin SOP package.

Memory IC Replacement Considerations

Direct pin-to-pin replacements may include other 2Mbit SPI FeRAM devices from manufacturers like Cypress/Infineon. Verify electrical characteristics, command sets, and package dimensions before substitution. Ensure the alternative component meets the same AEC-Q100 grade if automotive use is intended.
