MB85RC64TAPNF-G-AWERE2

Memory IC Overview

The MB85RC64TAPNF-G-AWERE2 is a 64 Kbit (8 K x 8) Ferroelectric Random Access Memory (FeRAM) integrated circuit manufactured by RAMXEED. It features an I2C serial interface with support for Standard, Fast, Fast Mode Plus, and High Speed modes operating up to 3.4 MHz. The device operates within a supply voltage range of 1.8 V to 3.6 V and supports an ambient temperature range from -40°C to +105°C. It utilizes an 8-pin plastic SOP package and includes hardware write protection capabilities.

Memory IC Feature Summary

• Nonvolatile memory cells retain data without backup batteries and offer high endurance exceeding 10^13 cycles per byte.
• I2C communication eliminates the need for polling sequences after writing operations, allowing immediate standby state entry.
• Hardware Write Protect pin disables all write operations when set to a high level while maintaining read access.
• Supports Sleep mode to reduce current consumption below standard standby levels through internal regulator control.

Memory IC Applications

• Data logging in battery-powered systems requiring long retention
• Industrial control systems needing high-speed nonvolatile storage
• Smart metering applications with frequent write cycles
• Embedded systems utilizing I2C bus architectures

Memory IC Procurement Notes

Verify the specific ordering suffix AWERE2 corresponds to the embossed carrier tape shipping form with a minimum quantity of 1500 units. Confirm that the 8-pin plastic SOP package dimensions match the design requirements. Ensure compliance with REACH and RoHS directives is documented for the manufacturing site. Check for any Product Change Notifications affecting the component specifications or assembly location prior to finalizing orders.

Memory IC Selection Notes

Select this component when an I2C interface is required instead of SPI-based alternatives like the MB85RS series. Choose this part for designs demanding operation at temperatures up to +105°C. Consider the 1.8 V to 3.6 V supply range compatibility with the system logic levels. Evaluate the 3.4 MHz High Speed mode capability against the master controller's performance limits.

Memory IC Part Context

This component belongs to the MB85RC64TA family of FeRAM devices produced by RAMXEED Limited, formerly Fujitsu Semiconductor Memory Solutions Limited. The manufacturer maintains original part numbering conventions while transitioning brand identity. The technology leverages ferroelectric process and silicon gate CMOS processes for nonvolatile cell formation.

Memory IC Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify cross-compatibility with other MB85RC64 variants based on package and interface requirements.
