MB85RS2MLYPN-G-AWEWE1

Memory IC Overview

The MB85RS2MLYPN-G-AWEWE1 is a 2Mbit (262,144 words x 8 bits) ferroelectric random access memory featuring a Serial Peripheral Interface. It operates within a supply voltage range of 1.7 V to 1.95 V and supports clock frequencies up to 50 MHz for most commands. The device provides high endurance of 10^13 read/write operations per byte and includes a unique 64-bit serial number. It is housed in an 8-pin plastic DFN package measuring 5 mm by 6 mm.

Memory IC Feature Summary

• Includes a dedicated special sector region with data stability guaranteed through multiple JEDEC MSL-3 reflow cycles.
• Features a factory-programmed 64-bit unique ID and a user-writable one-time serial number region.
• Supports SPI Mode 0 and Mode 3 communication protocols for flexible system integration.

Memory IC Applications

• High-temperature industrial applications requiring robust nonvolatile storage
• Automotive systems utilizing automotive-grade components
• Embedded controllers needing fast write speeds without erase cycles

Memory IC Procurement Notes

Verify the specific ordering suffix matches the required package type. Confirm that the application circuit strictly adheres to the narrow 1.7 V to 1.95 V operating voltage range. Ensure proper handling procedures are followed due to moisture sensitivity level 3 classification during assembly.

Memory IC Selection Notes

Select this component when a low-voltage SPI interface is required alongside extreme write endurance. It is suitable for designs where battery backup is undesirable but data retention at elevated temperatures is critical. Consider the DFN footprint constraints against available PCB space.

Memory IC FAQ

Is the data in the main memory array guaranteed after reflow?

No, data written before reflow cannot be guaranteed. Programming should occur after the reflow process, except for the special sector and serial number regions.

What is the maximum operating frequency for the READ command?

While the general maximum frequency is 50 MHz, the READ command specifically supports up to 40 MHz.
