MB85RS128TYPNF-G-BCE1

Memory IC Overview

The MB85RS128TYPNF-G-BCE1 is a 128Kbit (16K x 8) Ferroelectric Random Access Memory (FeRAM) utilizing SPI interface. It operates within a supply voltage range of 1.8V to 3.6V and supports clock frequencies up to 33 MHz. The device features high endurance of 10^13 read/write operations per byte and data retention exceeding 3.38 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 cells retain data without backup power, eliminating the need for SRAM batteries.
• High endurance capability allows for 10^13 read/write cycles per byte, significantly surpassing Flash and E2PROM limits.
• Supports Serial Peripheral Interface (SPI) modes 0 and 3 with operation speeds up to 33 MHz.
• Includes programmable block protection and write protect mechanisms via status register control.

Memory IC Applications

• Automotive systems requiring high-temperature reliability
• Industrial equipment needing frequent data logging
• Embedded controllers requiring fast nonvolatile storage

Memory IC Procurement Notes

Verify the specific ordering suffix matches the required shipping form. The BCE1 designation indicates tube packaging, whereas BCERE1 denotes tape and reel. Confirm moisture sensitivity level requirements and reflow soldering profiles prior to assembly to ensure data integrity.

Memory IC Selection Notes

Select this component when high-speed serial access and extreme endurance are critical. It serves as a direct replacement for battery-backed SRAM or standard EEPROM in applications demanding rapid write cycles. Ensure the system voltage aligns with the 1.8V to 3.6V operating range.
