MB85RC512TYPNF-G-BCE1

Memory IC Overview

The MB85RC512TYPNF-G-BCE1 is a 512Kbit (64 K x 8) Ferroelectric Random Access Memory (FeRAM) integrated circuit manufactured by RAMXEED. It utilizes a two-wire serial I2C interface and operates within a supply voltage range of 1.8 V to 3.6 V. The device supports standard, fast, fast mode plus, and high-speed modes with clock frequencies up to 3.4 MHz. It features an 8-pin plastic SOP package and is designed for operation across an ambient temperature range of -40°C to +125°C.

Memory IC Feature Summary

• Nonvolatile memory cells retain data without backup batteries and support at least 10^13 write cycles per byte.
• I2C interface allows direct connection to multiple slave devices on the same bus using hardware address pins.
• High-speed write operations eliminate the need for acknowledge polling sequences typically required by Flash or EEPROM.
• Hardware write protect pin enables disabling of all write operations while maintaining read access.

Memory IC Applications

• Data logging in industrial environments requiring frequent writes
• Configuration storage in battery-powered IoT devices
• Real-time data recording in automotive systems
• Metering applications needing long-term data retention

Memory IC Procurement Notes

Verify the specific ordering suffix 'BCE1' corresponds to the tube packaging format when sourcing components. Confirm that the selected variant matches the required operating temperature range and voltage specifications for the target application environment. Ensure compatibility with the host controller's I2C electrical levels before integration.

Memory IC Selection Notes

Select this component for designs requiring high endurance and low power consumption compared to traditional nonvolatile memories. Consider the I2C interface constraints and pull-up resistor requirements for the system bus. Evaluate the 8-pin SOP footprint against available PCB space and thermal management needs for high-temperature operation.

Memory IC Part Context

This part belongs to the MB85RC512TY family of FeRAM devices from RAMXEED, formerly Fujitsu Semiconductor. The manufacturer transitioned its name while maintaining existing part numbers and product support. This series is characterized by ferroelectric process technology combined with silicon gate CMOS processes for forming nonvolatile memory cells.

Memory IC Replacement Considerations

Direct substitutes are not explicitly listed in the provided documentation. Verify pinout and electrical compatibility if considering alternative FeRAM or EEPROM solutions. Check for any changes in I2C timing parameters or voltage thresholds that may affect system stability.
