MB85RS2MTAPF-G-BCE1

Memory IC Overview

The MB85RS2MTAPF-G-BCE1 is a 2 Mbit Ferroelectric Random Access Memory (FeRAM) integrated circuit manufactured by RAMXEED. It features a memory organization of 262,144 words by 8 bits and utilizes a Serial Peripheral Interface (SPI). The device supports operating frequencies up to 40 MHz and operates within a supply voltage range of 1.7 V to 3.6 V. It offers high endurance of 10^13 read/write operations per byte and data retention of 10 years at +85°C or 95 years at +55°C. The component is housed in an 8-pin plastic SOP package with a 208mil width and functions across an ambient temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Non-volatile ferroelectric memory technology enabling battery-less data retention without write wait times.
• High endurance capability supporting 10^13 read/write cycles per byte for frequent data logging applications.
• Serial Peripheral Interface (SPI) compatibility supporting Mode 0 and Mode 3 communication protocols.
• Integrated block protection and write protect mechanisms via status register configuration.

Memory IC Applications

• Battery management systems requiring frequent monitoring data recording.
• Industrial metering and measurement instruments needing long-term data retention.
• Automotive information recorders operating under varying thermal conditions.
• Embedded systems utilizing SPI interfaces for non-volatile parameter storage.

Memory IC Procurement Notes

Verify the specific ordering suffix to confirm the package dimensions and shipping format. The suffix BCE1 indicates an 8-pin plastic SOP with 208mil width supplied in tubes. Confirm moisture sensitivity level requirements and reflow soldering profiles prior to assembly. Ensure the design accommodates the specified operating voltage range and interface timing constraints defined in the datasheet.

Memory IC Selection Notes

Select this component when high endurance and fast write speeds are critical compared to Flash or EEPROM alternatives. The 2 Mbit capacity suits applications requiring substantial non-volatile storage in a compact footprint. Verify that the system voltage aligns with the 1.7 V to 3.6 V operating range. Consider the 8-pin SOP package constraints for PCB layout and thermal management during selection.

Memory IC Part Context

This part belongs to the MB85RS2MTA series of FeRAM devices from RAMXEED, formerly Fujitsu Semiconductor. The series provides non-volatile memory solutions combining the speed of SRAM with the non-volatility of Flash. RAMXEED continues to support these products under the new brand identity while maintaining original part numbering conventions.

Memory IC Replacement Considerations

Direct substitutes include other parts within the MB85RS2MTA family such as MB85RS2MTAPNF-G-BDERE1, which shares identical electrical characteristics but differs in packaging form factor and shipping quantity.
