MB85RS512TYPNF-GS-BCE1

Memory IC Overview

The MB85RS512TYPNF-GS-BCE1 is a 512Kbit (64K x 8) ferroelectric random access memory (FeRAM) integrated circuit manufactured by RAMXEED. It utilizes SPI interface technology and operates within a supply voltage range of 1.8V to 3.6V. The device supports a maximum clock frequency of 50 MHz and functions reliably across an ambient temperature range of -40°C to +125°C. It is housed in an 8-pin plastic SOP package with a lead pitch of 1.27mm.

Memory IC Feature Summary

• High endurance capability supporting up to 10^13 read/write operations per byte, significantly exceeding standard Flash or EEPROM technologies.
• Includes a dedicated special sector region of 256 words that guarantees data stability after three reflow cycles compliant with JEDEC MSL-3 standards.
• Features a unique 64-bit serial number and a unique ID for device identification, both maintained through reflow processes.
• Supports multiple low-power operational modes including Deep Power Down and Hibernate to minimize current consumption.

Memory IC Applications

• Automotive electronics requiring high-temperature reliability and AEC-Q100 compliance
• Industrial control systems needing non-volatile data retention without backup batteries
• Embedded devices requiring fast write speeds and high cycle endurance

Memory IC Procurement Notes

Verify the specific ordering suffix to confirm the shipping form, as the BCE1 designation indicates tube packaging. Confirm moisture sensitivity level requirements and storage conditions prior to assembly. Ensure compatibility with the host microcontroller's SPI mode settings. Check for any recent product change notifications regarding material composition or pinout adjustments.

Memory IC Selection Notes

Select this component when high-temperature operation up to 125°C is required alongside extensive write endurance. Consider the 8-pin SOP package constraints for board layout. Evaluate power consumption needs against the available standby and deep power down currents. Ensure the system voltage aligns with the 1.8V to 3.6V operating range.

Memory IC FAQ

What is the data retention period at maximum operating temperature?

At an ambient temperature of +125°C, the data retention is guaranteed for more than 5.9 years.

How does the special sector differ from the main memory array?

The special sector consists of 256 words and is specifically designed to guarantee data integrity after undergoing three reflow soldering cycles, unlike the general memory array.

Can the serial number be rewritten after initial programming?

No, the serial number region can only be written once using the WRSN command. After writing, it becomes permanently protected against overwriting.
