MB85RS2MTAPF-G-BCERE1

Memory IC Overview

The RAMXEED MB85RS2MTAPF-G-BCERE1 is a 2 Mbit (256 K x 8 bit) Ferroelectric Random Access Memory (FeRAM) integrated circuit. It utilizes a Serial Peripheral Interface (SPI) operating at a maximum frequency of 40 MHz. The device supports SPI modes 0 and 3, functions within a supply voltage range of 1.7 V to 3.6 V, and operates across an ambient temperature range of -40°C to +85°C. It is housed in an 8-pin plastic SOP package with a 208mil width.

Memory IC Feature Summary

• Nonvolatile memory architecture utilizing ferroelectric process technology for data retention without backup batteries.
• High endurance capability supporting up to 10^13 read/write operations per byte.
• Supports continuous programming mode allowing uninterrupted write cycles.
• Includes hardware write protection mechanisms via status register bits and dedicated pins.

Memory IC Applications

• Data logging systems requiring high-speed nonvolatile storage
• Industrial control applications needing frequent parameter updates
• Embedded systems with limited power budgets requiring low standby current

Memory IC Procurement Notes

Verify the specific package variant, as the suffix indicates an 8-pin plastic SOP with 208mil width. Confirm the shipping form corresponds to embossed carrier tape with a minimum quantity of 500 units. Ensure compatibility with the required SPI clock speed and voltage levels before integration into the design.

Memory IC Selection Notes

Select this component when high endurance and fast write speeds are critical compared to Flash or EEPROM alternatives. It is suitable for designs requiring battery-free data retention and support for continuous programming modes. Verify that the system voltage falls within the 1.7 V to 3.6 V range and that the 8-pin SOP footprint matches the PCB layout constraints.

Memory IC Part Context

This part belongs to the MB85RS2M family of FeRAM devices from RAMXEED, formerly Fujitsu Semiconductor Memory Solutions. The family offers various packaging and shipping options, including tubes and reels, with different pin pitches and widths. This specific model represents the standard 2 Mbit capacity configuration optimized for serial interface applications.

Memory IC Replacement Considerations

Direct substitutes include other parts within the MB85RS2M family such as MB85RS2MTAPNF-G-BDERE1, which shares identical electrical characteristics but differs in package dimensions (150mil vs 208mil) and shipping quantities.
