MB85RC64TAPNF-G-JNE2

Memory IC Overview

The MB85RC64TAPNF-G-JNE2 is a 64 Kbit (8,192 words x 8 bits) Ferroelectric Random Access Memory (FeRAM) integrated circuit manufactured by RAMXEED. It utilizes an I2C two-wire serial interface and operates within a supply voltage range of 1.8 V to 3.6 V. The device supports standard mode up to 100 kHz, fast mode up to 400 kHz, fast mode plus up to 1 MHz, and high-speed mode up to 3.4 MHz. It features a write endurance of at least 10^13 cycles per byte and data retention exceeding 19 years at +105°C. The component is housed in an 8-pin plastic SOP package and functions as an I2C slave device.

Memory IC Feature Summary

• Nonvolatile memory cells retain data without backup batteries, eliminating the need for polling sequences after writing operations.

Memory IC Applications

• Data logging systems requiring high write endurance
• Embedded controllers needing battery-free nonvolatile storage
• Industrial equipment operating in extended temperature ranges

Memory IC Procurement Notes

Verify the specific ordering suffix JNE2 corresponds to the 8-pin plastic SOP tube packaging format. Confirm that the manufacturer designation aligns with RAMXEED Limited, which succeeded Fujitsu Semiconductor Memory Solutions Limited. Ensure compatibility with I2C bus voltage levels between 1.8 V and 3.6 V before integration.

Memory IC Selection Notes

Select this component when high-speed I2C communication up to 3.4 MHz is required alongside extreme write endurance. It is suitable for applications demanding low standby current and operation across a wide ambient temperature range from -40°C to +105°C. Consider the 8-pin SOP footprint for surface-mount assembly constraints.

Memory IC Part Context

This part belongs to the MB85RC64TA series of FeRAM devices. RAMXEED Limited continues to offer and support these products while maintaining original Fujitsu part numbers. The technology combines ferroelectric process with silicon gate CMOS for forming nonvolatile memory cells.

Memory IC FAQ

Does the MB85RC64TAPNF-G-JNE2 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.

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

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