MB85RC64TAPNF-G-BDERE1

Memory IC Overview

The MB85RC64TAPNF-G-BDERE1 is a 64 Kbit (8 K x 8) Ferroelectric Random Access Memory (FeRAM) IC manufactured by RAMXEED. It features an I2C serial interface with a maximum clock frequency of 3.4 MHz in High Speed Mode and 1 MHz in Fast Mode Plus. The device operates on a supply voltage ranging from 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 a Write Protect pin for hardware security.

Memory IC Feature Summary

• Nonvolatile memory cells retain data without backup batteries, eliminating the need for polling sequences after writing operations.
• Supports high-speed bidirectional communication via a two-wire I2C bus with configurable device addressing for up to eight units.
• Hardware write protection allows disabling write operations while maintaining read access through a dedicated control pin.

Memory IC Applications

• Data logging systems requiring frequent write cycles
• Industrial equipment monitoring with high endurance requirements
• Smart metering applications needing reliable nonvolatile storage

Memory IC Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm the shipping form. This part number corresponds to the embossed carrier tape configuration. Ensure compatibility with existing PCB footprints for the 8-pin SOP package before finalizing procurement orders.

Memory IC Selection Notes

Select this component when designing systems that require high write endurance and fast random access speeds without the latency associated with Flash memory polling. It is suitable for applications demanding low power consumption in standby and sleep modes while operating within standard industrial temperature ranges.

Memory IC Part Context

Memory IC FAQ

Does the MB85RC64TAPNF-G-BDERE1 require an acknowledge polling sequence after writing?

No, the device performs write operations at the same speed as read operations, so no waiting time for ACK polling occurs after issuing the stop condition.

How many devices can be connected to the same I2C bus?

Up to eight devices can be connected to the same data bus, identified by unique combinations of the A0, A1, and A2 address pins.
