MB85RC64TAPNF-G-JNERE2

Memory IC Overview

The MB85RC64TAPNF-G-JNERE2 is a 64 Kbit (8K 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 of -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 architecture retains data without backup power
• I2C two-wire serial interface supporting multiple communication speeds
• Hardware write protect pin disables writing operations when active
• High endurance rating significantly exceeding Flash and EEPROM technologies

Memory IC Applications

• Data logging in battery-free systems
• Industrial control systems requiring high-speed nonvolatile storage
• Smart metering applications
• Embedded systems needing frequent write cycles

Memory IC Procurement Notes

Verify the specific ordering suffix JNERE2 corresponds to the embossed carrier tape shipping form with a minimum quantity of 1500 units. Confirm that the component meets REACH regulations and EU RoHS Directive compliance requirements before integration into final assemblies.

Memory IC Selection Notes

Select this component for designs requiring high write endurance and fast access times without polling delays. Ensure the system controller supports the required I2C clock frequencies and address configurations. Verify that the 8-pin SOP footprint matches the PCB layout constraints and thermal management requirements.
