MB85RC256TYPN-GS-AME1

Memory IC Overview

The MB85RC256TYPN-GS-AME1 is a 256 Kbit (32 K x 8) Ferroelectric Random Access Memory (FeRAM) compliant with AEC-Q100 standards. It features an I2C serial interface supporting Standard, Fast, Fast Plus, and High Speed modes up to 3.4 MHz. The device operates on a supply voltage of 1.8 V to 3.6 V within an ambient temperature range of -40°C to +125°C. It offers high endurance of at least 10^13 write cycles and data retention up to 70.4 years at +85°C. The component is available in an 8-pin plastic SOP or DFN package.

Memory IC Feature Summary

• AEC-Q100 automotive qualification for reliability under harsh conditions
• Nonvolatile memory architecture eliminating the need for backup batteries
• High-speed write operations without polling wait times required after stop conditions
• Integrated sleep mode functionality to minimize standby current consumption

Memory IC Applications

• Automotive electronic control units requiring non-volatile data storage
• Industrial systems operating at elevated temperatures up to 125°C
• Embedded controllers needing high endurance for frequent parameter logging
• IoT devices utilizing low-power I2C communication interfaces

Memory IC Procurement Notes

Verify the specific package type (SOP or DFN) and shipping form (Tube, Reel, or Tray) against the ordering information table, as suffixes determine physical dimensions and packing quantities. Confirm that the manufacturer ID and product ID match the datasheet specifications during incoming inspection to ensure authenticity. Check moisture sensitivity level requirements before soldering.

Memory IC Selection Notes

Select this component when automotive grade certification is mandatory for the application environment. Choose this model over standard FeRAM variants if operation above 85°C is required. Ensure the system design supports the 1.8 V to 3.6 V supply range and utilizes pull-up resistors for the open-drain I2C lines. Consider the High Speed mode capability if bus bandwidth exceeds 1 MHz limits.

Memory IC Part Context

This part belongs to the MB85RC256TY series manufactured by RAMXEED Limited, formerly Fujitsu Semiconductor Memory Solutions Limited. The series represents a transition from traditional Flash or EEPROM technologies to Ferroelectric memory, offering superior write speeds and endurance. The MB85RC256TYPN-GS-AME1 specifically denotes a variant within this family, likely corresponding to a specific packaging or environmental code defined by the manufacturer's internal nomenclature.

Memory IC Replacement Considerations

Direct replacements include other MB85RC256TY variants such as MB85RC256TYPNF-GS-BCE1 or MB85RC256TYPN-GS-AWE1, provided the package footprint (SOP vs DFN) matches the PCB layout. Verify that any substitute maintains AEC-Q100 compliance and identical pinout configurations for SDA, SCL, WP, and address pins.
