MB85RS64VYPN-G-AMEWE1

Memory IC Overview

The MB85RS64VYPN-G-AMEWE1 is a 64Kbit (8K x 8) Ferroelectric Random Access Memory (FeRAM) integrated circuit manufactured by RAMXEED. It utilizes the Serial Peripheral Interface (SPI) for communication and operates within a supply voltage range of 2.7V to 5.5V. The device supports clock frequencies up to 25 MHz at lower voltages and 33 MHz at higher voltages. It is housed in an 8-pin plastic Small Outline Non-leaded (SON) package with dimensions of 2.0mm x 3.0mm. The component is qualified under AEC-Q100 standards, ensuring reliability for automotive applications across an ambient temperature range of -40°C to +125°C.

Memory IC Feature Summary

• Nonvolatile memory architecture utilizing ferroelectric process technology eliminates the need for backup batteries while supporting high endurance write cycles.

Memory IC Applications

• Automotive electronic systems requiring AEC-Q100 qualification
• Data logging applications demanding high write endurance
• Industrial control systems operating in extreme temperature environments

Memory IC Procurement Notes

Verify the specific ordering suffix to confirm the package type and shipping format, as variations exist within the MB85RS64VY family. Ensure compatibility with the target system's SPI mode requirements, specifically Mode 0 or Mode 3. Confirm that the design accommodates the 8-pin SON footprint dimensions and thermal characteristics specified in the datasheet.

Memory IC Selection Notes

Select this component when a nonvolatile memory solution requires high write endurance without the latency associated with Flash memory. The wide operating voltage range allows flexibility in power supply design. The AEC-Q100 qualification makes it suitable for automotive environments where long-term reliability and extended temperature operation are critical constraints.
