MB85RS64VYPNF-GS-AWE2

Memory IC Overview

The MB85RS64VYPNF-GS-AWE2 is a 64Kbit Ferroelectric Random Access Memory (FeRAM) IC manufactured by RAMXEED. It features an SPI interface with a maximum clock frequency of 33 MHz at voltages between 4.5V and 5.5V, and 25 MHz between 2.7V and 4.5V. The device operates within a supply voltage range of 2.7V to 5.5V and supports an ambient temperature range from -40°C to +125°C. It utilizes an 8-pin plastic SOP package and complies with AEC-Q100 Grade 1 standards.

Memory IC Feature Summary

• High endurance capability supporting up to 10^13 read/write operations per byte without requiring backup batteries.
• Supports SPI Mode 0 and Mode 3 communication protocols for flexible system integration.
• Includes block protection and write protect functions controlled via the status register and WP pin.
• Features low power consumption modes including standby and sleep states.

Memory IC Applications

• Automotive electronic systems requiring high-temperature reliability
• Industrial control applications needing frequent data logging
• Embedded systems requiring non-volatile memory with fast write speeds

Memory IC Procurement Notes

Verify the specific ordering suffix corresponds to the tube packaging format required for this part number. Confirm that the component meets AEC-Q100 Grade 1 automotive qualification requirements if used in vehicle electronics. Ensure the design accounts for the specified moisture sensitivity level during reflow soldering processes.

Memory IC Selection Notes

Select this component when high endurance and fast write times are critical compared to Flash or EEPROM alternatives. Consider the 8-pin SOP package constraints for PCB layout. Evaluate the operating voltage range against the system's power supply rails to ensure compatibility across the full temperature spectrum.

Memory IC FAQ

What is the maximum clock frequency supported by this device?

The device supports a maximum clock frequency of 33 MHz when the supply voltage is between 4.5V and 5.5V, and 25 MHz when the voltage is between 2.7V and 4.5V.

How does the device handle write protection?

Write protection is managed through the Status Register bits BP0 and BP1 for block protection, and the WPEN and WP pins for controlling access to the status register itself.
