MB85RS64VYPNF-G-AWERE2

Memory IC Overview

The MB85RS64VYPNF-G-AWERE2 is a 64 Kbit (8K x 8) Ferroelectric Random Access Memory (FeRAM) integrated circuit manufactured by RAMXEED. It utilizes a Serial Peripheral Interface (SPI) for communication and operates within a supply voltage range of 2.7 V to 5.5 V. The device supports clock frequencies up to 25 MHz at lower voltages and 33 MHz at higher voltages. It is housed in an 8-pin plastic Small Outline Package (SOP) and is designed for industrial applications with an operating temperature range from -40 °C to +125 °C.

Memory IC Feature Summary

• Nonvolatile memory architecture utilizing ferroelectric process technology that retains data without backup power.
• High endurance capability supporting 10^13 read/write operations per byte, exceeding standard Flash or EEPROM limits.
• Integrated SPI controller compatible with Mode 0 and Mode 3 protocols, featuring dedicated Hold and Write Protect pins.

Memory IC Applications

• Industrial control systems requiring frequent data logging
• Automotive electronics compliant with AEC-Q100 standards
• Smart metering devices needing long-term data retention

Memory IC Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and shipping form. Ensure compatibility with system voltage levels and SPI timing requirements before integration. Confirm moisture sensitivity handling procedures are followed during assembly.

Memory IC Selection Notes

Select this component when high write endurance and fast write speeds are critical compared to Flash memory. It is suitable for designs requiring battery-free data retention and wide temperature operation. Consider the SOP-8 footprint constraints and SPI interface compatibility with the host microcontroller.

Memory IC Part Context

This part belongs to the MB85RS64VY series of FeRAM devices produced by RAMXEED Limited, formerly Fujitsu Semiconductor Memory Solutions Limited. The series maintains original Fujitsu part numbering conventions while offering updated manufacturing support and compliance with modern environmental regulations such as RoHS.

Memory IC Replacement Considerations

Direct substitutes include other 64 Kbit SPI FeRAM devices from manufacturers like Cypress/Infineon, provided pinouts and command sets are verified. Cross-referencing electrical characteristics and package dimensions is essential for mechanical fit.
