MB85RS256TYPNF-G-BCERE1

Memory IC Overview

The MB85RS256TYPNF-G-BCERE1 is a 256 Kbit Ferroelectric Random Access Memory (FeRAM) IC manufactured by RAMXEED. It features a 32 K x 8 bit organization and utilizes a Serial Peripheral Interface (SPI) compatible with modes 0 and 3, supporting a maximum operating frequency of 33 MHz. The device operates within a supply voltage range of 1.8 V to 3.6 V and is housed in an 8-pin plastic SOP package. It is qualified for AEC-Q100 standards and supports an extended ambient temperature range from -40 °C to +125 °C.

Memory IC Feature Summary

• High endurance capability offering 10^13 read/write operations per byte
• Nonvolatile data retention without requiring backup batteries
• Fast write cycle times eliminating waiting periods associated with Flash or EEPROM technologies
• Integrated block protection and write protect functions via status register control

Memory IC Applications

• Automotive systems requiring high-temperature reliability
• Industrial equipment needing frequent data logging
• Embedded controllers requiring fast nonvolatile storage

Memory IC Procurement Notes

Verify the specific ordering suffix matches the required packaging format, as the BCERE1 designation indicates tape and reel shipping. Confirm that the component meets the necessary automotive qualification standards if deployed in vehicle electronics. Ensure the design accounts for the specified moisture sensitivity level during surface mount assembly processes.

Memory IC Selection Notes

Select this component when a design requires high-speed SPI communication combined with extreme durability against repeated write cycles. It serves as a suitable replacement for SRAM or EEPROM in applications where battery backup is undesirable. Consider the 1.8 V to 3.6 V supply range compatibility with the target microcontroller logic levels.

Memory IC Part Context

This part belongs to the MB85RS256TY family of FeRAM devices produced by RAMXEED Limited, formerly Fujitsu Semiconductor Memory Solutions Limited. The manufacturer continues to support existing product lines under the new corporate identity while maintaining original part numbering conventions for continuity in global supply chains.

Memory IC Replacement Considerations

Compatible substitutes include the MB85RS256BPNF-G-JNERE1 and MB85RS256TYPNF-G-AWERE2. Verify pinout compatibility and ensure the alternative package variant meets the same thermal and electrical specifications required by the application.
