MB85RC256VPF-G-BCERE1

Memory IC Overview

The MB85RC256VPF-G-BCERE1 is a 256 Kbit (32 K x 8) Ferroelectric Random Access Memory (FeRAM) utilizing an I2C serial interface. It operates within a supply voltage range of 2.7 V to 5.5 V and supports a maximum clock frequency of 1 MHz. The device features a write endurance of at least 10^12 cycles per byte and data retention exceeding 10 years at +85°C. It is housed in an 8-pin plastic SOP package with a 208mil width, designed for surface mount technology.

Memory IC Feature Summary

• Nonvolatile memory cells retain data without backup batteries, eliminating the need for polling sequences after writing operations.
• High write endurance allows for extensive data rewriting cycles compared to other nonvolatile memory products.
• Integrated hardware write protect pin disables writing operations when set to a high level while maintaining read access.
• Supports multiple slave devices on a single bus through configurable hardware address pins.

Memory IC Applications

• Industrial control systems requiring frequent data logging
• Smart metering infrastructure for measurement data storage
• Automotive information recording modules
• Embedded systems needing battery-free nonvolatile storage

Memory IC Procurement Notes

Verify the specific ordering suffix matches the required package dimensions and shipping format. Confirm that the 208mil SOP variant aligns with PCB footprint specifications. Ensure compatibility with the target I2C bus voltage levels and check for any recent product change notifications affecting lead-free status or manufacturing location.

Memory IC Selection Notes

Select this component when a two-wire serial interface is preferred over SPI for system simplicity. Choose this FeRAM variant for applications demanding high write durability and immediate data persistence without programming wait times. Consider the operating temperature range and voltage requirements to ensure alignment with the host controller's electrical characteristics.
