MB85RS64VYPNF-GS-BCERE1

Memory IC Overview

The MB85RS64VYPNF-GS-BCERE1 is a 64Kbit (8K x 8) Ferroelectric Random Access Memory (FeRAM) utilizing SPI interface technology. It operates within a supply voltage range of 2.7V to 5.5V and supports clock frequencies up to 25 MHz at lower voltages and 33 MHz at higher voltages. The device features high endurance of 10^13 read/write operations per byte and data retention exceeding 5.9 years at +125°C. Designed for automotive environments, it complies with AEC-Q100 Grade 1 standards and functions across an ambient temperature range of -40°C to +125°C in an 8-pin SOP package.

Memory IC Feature Summary

• Non-volatile memory architecture eliminates the need for backup batteries while retaining data without power.
• High rewrite endurance allows for frequent data logging without degradation compared to Flash or EEPROM technologies.
• Fast write cycle times enable immediate data recording without waiting periods associated with other non-volatile memories.
• Robust resistance to magnetic fields ensures reliable operation in electrically noisy environments such as motor applications.

Memory IC Applications

• Automotive battery management systems requiring high-frequency data logging under extreme temperatures.
• Rotary encoders needing continuous speed calculation and data storage without battery support.
• Industrial equipment monitoring where high durability and fast write speeds are critical for system reliability.

Memory IC Procurement Notes

Verify that the specific suffix BCERE1 corresponds to the embossed carrier tape shipping form required for your assembly line. Confirm that the component meets AEC-Q100 Grade 1 specifications if your design mandates automotive-grade qualification. Ensure your PCB layout accounts for the 8-pin SOP dimensions and moisture sensitivity level requirements during reflow soldering processes.

Memory IC Selection Notes

Select this component when designing systems that require frequent data updates without the wear-out limitations of Flash memory. It is suitable for applications operating between 2.7V and 5.5V where low standby current is beneficial. Consider this part for space-constrained designs needing SPI connectivity and robust performance in high-temperature automotive or industrial sectors.

Memory IC FAQ

How does the hold pin function during serial communication?

The HOLD pin allows interruption of serial input/output without deselecting the chip. When held low, SO becomes High-Z and SCK/SI inputs are ignored, preserving the command state until the pin returns high.

What is the data retention capability at maximum operating temperature?

At an ambient temperature of +125°C, the data retention is specified as 5.9 years or more, based on qualification results for the first reading/writing data after shipment.
