MB85RC512TYPNF-GS-BCERE1

Memory IC Overview

The MB85RC512TYPNF-GS-BCERE1 is a 512Kbit (64 K × 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 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 +125°C. It is housed in an 8-pin plastic SOP package.

Memory IC Feature Summary

• Nonvolatile memory architecture eliminates the need for data backup batteries while retaining data without power.
• High write endurance capability significantly exceeding standard nonvolatile memory products.
• Direct I2C bus integration allows connection of multiple slave devices using hardware address pins.
• No polling sequence required after write operations, enabling immediate subsequent commands.

Memory IC Applications

• Data logging systems requiring high endurance and battery-free retention
• Industrial control interfaces utilizing I2C communication protocols
• Automotive electronics compliant with AEC-Q100 standards
• Embedded systems operating in extended temperature environments

Memory IC Procurement Notes

Verify the specific ordering suffix corresponds to the desired packaging format. The suffix BCERE1 indicates the component is supplied in embossed carrier tape. Confirm that the selected package variant matches the intended PCB footprint requirements for the 8-pin plastic SOP configuration before finalizing procurement orders.

Memory IC Selection Notes

Select this component when an I2C interface is required alongside high write endurance and wide temperature operation. Ensure the system design accommodates the 1.8 V to 3.6 V supply voltage range. Verify that the master controller supports the necessary I2C clock frequencies, including High Speed mode if maximum throughput is required for the application.

Memory IC Part Context

This part belongs to the MB85RC512TY series of FeRAM devices produced by RAMXEED Limited. The manufacturer continues to offer these products under original Fujitsu part numbers following its name change from Fujitsu Semiconductor Memory Solutions Limited.

Memory IC FAQ

Does the MB85RC512TYPNF-GS-BCERE1 require an acknowledge polling sequence after writing?

No, the device performs high-speed write operations and does not require any waiting time or acknowledge polling sequence after issuing a stop condition.

How is the device address configured on the I2C bus?

The device address is determined by the logic levels applied to the external hardware pins A0, A1, and A2, allowing up to eight devices to be connected to the same bus.

What is the function of the Write Protect (WP) pin?

Setting the WP pin to a high level disables all writing operations to the memory array, while keeping reading operations enabled. The pin is internally pulled down to the low level when left open.
