MB85RS2MLYPN-GS-AWEWE1

Memory IC Overview

The MB85RS2MLY is a 2 Mbit (262,144 words x 8 bits) Ferroelectric Random Access Memory (FeRAM) utilizing SPI interface. It operates within a supply voltage range of 1.7 V to 1.95 V and supports clock frequencies up to 50 MHz. The device features high endurance of 10^13 read/write operations per byte and data retention exceeding 50 years at +85°C. It includes a unique 64-bit serial number and a special sector region for reflow-stable storage. Operating temperature ranges from -40°C to +125°C, with AEC-Q100 Grade 1 compliance.

Memory IC Feature Summary

• AEC-Q100 Grade 1 compliant for automotive-grade reliability
• Includes a dedicated special sector region stable after three JEDEC MSL-3 reflow cycles
• Features a factory-programmed 64-bit Unique ID and writable Serial Number
• Supports standard SPI modes 0 and 3 with block protection capabilities

Memory IC Applications

• Automotive electronic systems requiring high-temperature operation
• Industrial control applications needing high write endurance
• Data logging systems requiring fast non-volatile storage without backup batteries

Memory IC Procurement Notes

Verify the specific package variant required, as the MB85RS2MLY family includes both SOP-8 and DFN-8 options. Confirm that the system design strictly adheres to the narrow 1.7 V to 1.95 V operating voltage range, as this component does not support wider voltage rails like 3.3 V or 5 V. Ensure ESD handling protocols meet the specified HBM and CDM ratings during assembly.

Memory IC Selection Notes

Select this component when a low-voltage (1.8 V nominal) SPI memory is required for harsh environments. It is suitable for designs prioritizing write speed and endurance over Flash or EEPROM alternatives. Verify compatibility with the narrow voltage window and ensure the PCB layout accommodates the chosen SOP or DFN footprint.

Memory IC Part Context

This part belongs to the RAMXEED MB85RS2M series of SPI FeRAM devices. It represents the automotive-compliant variant of the broader MB85RS2ML family, offering specialized stability features for manufacturing processes involving multiple reflow cycles.

Memory IC Replacement Considerations

Direct pin-to-pin replacements are limited due to the specific 1.7 V–1.95 V voltage constraint. Other parts in the MB85RS2M family may differ in package type or voltage tolerance.
