MB85RS64VYPNF-G-BCE1

Memory IC Overview

The MB85RS64VYPNF-G-BCE1 is a 64Kbit (8K x 8) Ferroelectric Random Access Memory (FeRAM) utilizing SPI interface technology. It operates within a 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. It functions in an ambient temperature range of -40°C to +125°C and is housed in an 8-pin plastic SOP package.

Memory IC Feature Summary

• Nonvolatile memory architecture eliminates the need for backup batteries while providing significantly faster write cycle times compared to Flash or E2PROM technologies.
• Supports Serial Peripheral Interface (SPI) Mode 0 and Mode 3 with dedicated hold functionality to interrupt serial I/O without deselecting the chip.
• Includes hardware-level write protection mechanisms via status register bits and physical pins, alongside block protection capabilities for specific memory segments.

Memory IC Applications

• Data logging systems requiring frequent updates and high endurance
• Industrial control applications operating in extreme temperature environments
• Embedded systems needing fast, battery-free nonvolatile storage

Memory IC Procurement Notes

Verify that the ordering suffix corresponds to the required shipping form, as this part number indicates tube packaging. Confirm compatibility with the target system's voltage levels and SPI timing requirements. Ensure proper handling procedures are followed due to moisture sensitivity classification. Cross-reference the manufacturer ID and product ID using the RDID command if necessary for authentication.

Memory IC Selection Notes

Select this component when high write endurance and low power consumption are critical. It is suitable for designs requiring operation across a wide temperature range without external backup power. Consider the 8-pin SOP package constraints for PCB layout. Evaluate the standby and sleep current specifications against total system power budgets.
